Hello again guys. Finally had time today to do a few posts on the upgrades I have done to my 2014 Moto Guzzi California Custom 1400.
I mentioned already about the dealer doing a OEM Guzzi remap flash upgrade fix for my 1400's terrible idle and low end performance. I rode the bike a lot with the new Map and the bike was 80% perfect, still a bit of hot soaked lean idle but at least constantly able to recover to 1100 rpm idle at traffic lights etc.
As my bike was so bad, before I took it in for the new tires and dealer found out about the available new factory map for it! I had already ordered a plug and play Boost Plug kit for my 1400.
The Booster Plug is a small smart black box that plugs in between the OEM intake Air Temp sensor and Guzzi Magneti Marelli PCM, thus by allowing the Booster Plug box to increase the air-fuel mixture above the factory current intake air temp setting used by internal mapping. The BP using its own attached air temp sensor that sits remote out away from the engine heat. Basically a smart simple idea, the slope in the tiny Booster Plug box tells the factory ECU that the air temp is cooler i.e. more dense than it actually is so the factory Ecu enriches the fuel mixture accordingly. The slope in the unit makes sure that it does not go too rich when intake air temps are actually really cold, like a Canada fall ride morning. Very smart little unit, more info about how it works at their site, see link. all plug and play no wires to cut or mess with, just plug it in with factory connectors and all. I just needed to lift the gas tank about the thickness of a 2x4 at the back to gain access to the top of the intake manifold where the IAT sensor is located, it plugs in line with the original connectors, easy peasy. Then run the long wire with BP temp sensor up to the front of the main post or triple tree, there is just enough wire, these guys have thought this thing out.
After the install my 1400 runs even nicer than it had after the new Fuel Map from Piaggio. My idle is dead solid all the time and no more shaking due to lean misfires. All in all well worth the 170 bucks, plus reasonable shipping cost from Denmark.
I have used this product on my 2020 Kawasaki Z900RS, it was a nice running bike but also very lean operation , snatchy response and lean idle , it fixed up my Z900 so nicely I ordered it for my 1400, will make another post on how it works after my new Map has been installed. The booster plug is plug and play easy to install. On the Z900RS I did remove my gas tank fully without realizing I could have just lifted the tank up. Gave me a chance to look at my air filter and gave me more room to route the BP temp sensor and harness to the front of the bike. They make them for many makes and models of bike and most of the Moto Guzzi's, see link at bottom below pic's.

I put a Booster Plug on my 1400 Audace, it helped but the bike still had issues. The low speed poor running contributed to a drop last summer. I didn't know there was an upgrade flash and my dealer probably couldn't have cared less. Beetle had withdrawn his 1400 map due to a couple of bricked ECMs. I have sold the bike because my aging body couldn't cope with mass and slow speed handling. Good luck with yours, I miss the awesome power. It was fun embarrassing my Harley buddies. Maybe that's why they all moved to Arizona. :evil:

I bought that black box for my 2015 Cali Custom (Blu Guzz). I thought the bike ran ok before install, but it was even better after, I think it was the Mistral product.

Nice Z900RS!

I can't believe people fall for this add on rubbish. With Guzzidiag available for free why would you bother with "smoke and mirrors" junk.

My 2017 Stelvio was hugely improved at low throttle running with the booster plug. Simple installation but the sensor cord was too short to run up front. I put it in front of the air intake in back. Have tried with or without - much better with the plug. It increases the fuel by 6% at low throttle. I have nothing against Guzzidiag but don’t have a portable pc and don’t have the knowledge and confidence to mess around with a perfectly good and expensive mg computer.

Nice Z900RS!

Thanks, yes it’s a very nice bike, the motor has a huge wide power band, overall the handling is fantastic and well rounded. This is not a Z900 forum but for any others out there, I like to have a different bike to ride at different times. I love my Cali 1400 very much for cruising the smooth highways around Calgary Alberta and kananaskis country and Banff national park. The Cali 1400 is smooth and fast now. I have my Z900RS in Bullhead City, Az. Last winter when we were down in AZ, my friend found us 2 Moto Guzzi 1100 Californias that had been sitting in a mostly covered carport in town. They had been sitting for 5 years with dead fuel systems. We purchased both of them for 900 USD each and started working on them right away. My Buddy Eric ended up with the Sidecar 1100, and I got the Silver Stone 1100. A few pictures attached but we had a blast with them this winter and I loved riding the Stone so much when I got back to Canada I was sure I wanted to buy a 1400 and I'm glad I did now that I have the 1400 running so nicely.

Hello Phil. I'm actually a retired Mechanical Engineer, I worked in Europe for TTE and Toyota F1 back in the days when Toyota had mojo. Anyway that said I have 50 years experience racing cars and even snow machines. The thinking behind the Booster Plug is very simple and works without effecting anything down stream of the Air Temp sensor. Its actually an well Engineered easy to install device that does not hurt anything on the bikes existing systems. It just allows the stock ECU to add a little more fuel to the tune via the factory air temp sensor table. That’s it simple and it works , not JUNK. Re; GuzziDag I'm not sure that is anything more than a code reader for the 1400, at least from what I have read on here, maybe others can chime in as I thought the only way to tune the 1400 is via OEM factory flash or using piggy back computers in which case I agree with you on that method as a poor method. Anyway, have a great ride, stay safe! Reg Riemer

Well I've used both on my 2018 Eldorado . Was quite pleased with the improvement in low speed running with the Booster Plug .
Anything to do with more power was of no interest to me , it's got plenty with a few revs . I ran it for a little
over 5000 kms , no problems . But I had this desire to try the "Beetle Maps" with the "GuzziDiag" program.
My computer literacy ended with DOS :) . I got a map from Beetle a bit over a year ago and succeeded in getting
it installed ,( did I say I reread the instructions at least a dozen times) . I used a Windows laptop with Win 7 as
per suggestions and am now even happier with it's running . It's not a ten minute task ! Even without the remapping , the
GuzziDiag is a great diagnostic program . I've heard that he's no longer offering maps for the 1400's , but I can't verify that.
Pity if it's true . Peter

I'm gong to apply the Roper principle on this topic and just say no more. It's a pointless proposition.

Love your Moto Guzzi Cali 1100 story, must have been lot of fun. I like this kinda stuff.
I almost want to ask you if you want to sell your Cali 1100 to me. He He.
I like your Cali 1100..nice.

So when you say it is a "well engineered easy to install device that doesn't hurt anything" I have a follow up question for you.
What's so elegant about it?
I originally bought into the concept based on the simple assumption that emissions regulated vehicles are "lean" to make standards.
Then I learned that it's not that black and white.
The unintended consequences of emissions regulations are the weird conditions under which they are tested. Regulating bodies created conditions that must be abnormally lean while allowing other, unregulated, portions of the map to be pig rich.
The result are a number of OEM maps that go from rich to lean and then back to rich again based on whether the rpm is a test condition or not.
So let's take the logic of these units and apply them across a map that isn't always lean, what happens?
We have anecdotes where they have indeed caused harm. But even if those are nothing more than anecdotes I don't see where just making everything more rich is necessarily the answer. It reminds me of those pig rich, disgusting smelling shovelheads I'd sometimes get stuck riding behind. Then the truth wasn't that they NEEDED to be that pig rich, it's just that the average Joe made similar assumptions and just went rich over lean at the cost of both performance and efficiency.
I just feel like we should at least consider the more elegant solution (when available).
Edit - I've experimented with these devices on both Guzzis and Harleys and, truthfully at first sometimes convinced myself they worked. But on further objective testing I found they weren't really doing much of anything. Subsequent remapping of those ECU's showed much more dramatic, objective, and replicable results. So I guess I always wonder if the person claiming success isn't also fooling themselves.

Not sure why you're taking my sincere question and explanation so personally but no offense was meant.
That said, follow up question. Did you have to work much with mapping to meet EU regulation testing in F1?

If it's much more technical than checking tire pressure with a pencil type tire gauge I'm lost, so heck if I know. But I had a Ducati Scrambler that was difficult to ride at slow speeds, it seemed it wouldn't take throttle reliably and wanted to lurch and stutter. This made it a pain in any sort of tight spot, such as coming around the corner in our gravel driveway, circling around gas pumps, navigating traffic in town. Our driveway is just beyond the crest of a blind hill, definitely not a place for a sketchy take-offs, so I always had a slight feeling of dread leaving the house. Anyway, the Booster Plug made all the difference in my situation, did exactly what I'd hoped it would do, and I couldn't tell it hurt performance in any way. It just eliminated that "iffy" throttle response right off idle. From a mechanical/engineering standpoint, was this not possible? I'm not trying to argue, just sharing my experience and interested to learn more.

Hello all. I did not save my factory spark plugs that I pulled out when I did my service and installed the touring handle bars but my OEM spark plugs are dead chalk white crispy, base circle is white, sparkles on the porcelain indicated that the motor had pre ignition conditions as well. Ground strap indicated that the temp range was on the hot end of the plugs range, the color change on the strap was nearly at the base circle. Anyway, no pig rich conditions on my 1400, dead lean is all.
If a motor has a totally bad tune where its lean and rich all over the places in the map there is no add on device that will fix it correctly. The only way is to tune the motor so that it's running correctly via the tables that are in the factory PCM.
I did not know that there was a way you could flash a new tune into the these 1400 pcms. Can someone chime in who Beatle is and how to do this. When I asked about this at the GuzziTec forum moderator said the only was was with Dynojet piggy back's and a mess of stuff added to the system, they were very to the point that they were the only ones that know what they are talking about and that a flash tune was not possible on the 1400, so I'm not sure what to say guys. Anyway my 1400 is running nicely anyway now between the factory updated Map and the booster air temp trick.
In F1 and FIA Rally the mapping is not based on EPA standards for Europe Asia or North America. In racing the mapping is for engine durability balanced with maximum power and fuel economy is also very important as fuel quantities are limited based on the race criteria.
However any of the products offered by say, BMW, Honda, Toyota or other brands that are fitted to road going passenger cars the EPA guidelines are always held very strictly. Any of the products I worked on in the days gone like supercharge kits etc that are fitted after the car leaves the assembly line are tested to the ninth degree by EPA and for example in Germany the TUV. In Japan I worked with HKS Company near Mount Fuji and for the Japanese the same can be said every T crossed and i dotted all the way to the bottom of the file.

Cheers guys. Ride safe, the cars on the road don't see us out there.

Actually thats what a Power Commander is able to due to its many more data points. It greatly improved my ‘98 EV which two aftermarket replacement chips were unable to accomplish.

Yes it can be done to fix a bad tune, its not easy that said as O2 feedback will fight the changes and often the scaling is not matched as per KPA versus RPM many Factory PCM's have a lot more resolution in the tables than the piggy back that’s used to over lay the corrections, say the factory pcm has 200 rpm per cell and a 32 x 32 table and the piggy back has 500 rpm per cell and maybe 16 x 16. Only the tuner can know how it will fit over the top, then add in the factory pcm feedback and correction tables for enrichment tables etc. I fun science project no doubt.
However if the tuner Beetle can just flash the factory ecu with a smoothed out nice map and in this cases often the stoichiometric o2 target point can be also scaled based on load table as with say GM or Toyota BMW and other pcms.
When I was working at TTE and HKS, we used piggy back ecus to some degree deepening on what stock ECU was setup like. Motorbikes and older cars sometimes used very simple layout like Alpha N which is just TPS point and RPM as the X and Y and maybe 16 x 16 or 24 x 24 tables, very easy to use a outside ECU to adjust the pulse width of injector output after it comes out of the stock ECU. HKS had one unit like this called the F-Con iS. As well HKS offered us the F-con Vpro PCM that directly replaced the outputs to the Injectors and coil control via its own spark advance tables, the Vpro only using the stock ECU's sensor inputs for RPM, Cam, TPS, IAT, WT, O2, etc, in a sense sitting on top of the stock PCM like a spider taking over control completely, even idle control, boost control, traction control all done by the Vpro sitting on top of the stock system. This was a very good way to go as the stock ECU is basically taken out of the control process altogether, and the Vpro would actually have its own 32 x 32 feedback O2 table where it can make its own corrections to the base fuel table. Another advantage was that the Vpro could output signals back to the stock ecu to keep it happy and keep the MIL error codes away and thus allow the vehicle to go into a smog test as any data pulled out of the stock ecu via OBD2 would look like a happy sunny motor in there, even thou the motor was capable now of say 750 HP and have multiple maps for different fuels etc.
Anyway, not to bore everybody on this topic. For me it brings back a lot of my work and my own racing days.
Attached a old pic of my brand new 1994 HKS, TRD, TTE backed Toyota Supra Twin Turbo back in the One Lap of America Days, we ran this race 7 times with a best of 4th overall. A lot of fun, this was a Single Turbo 3 litre inline 6 engine running on our HKS Fcon Vpro and making 600 rear wheel HP on VP fuel.
Not Guzzi related but some of our group might get a kick out of the old shots. Anyway fun chatting about this , if someone knows how to contact Beetle I would love to chat with him about our 1400's and others, I would like to tune my 2004 Califorina 1100 as well that would be great to get setup to flash these bikes. Not that I want more power or anything but what the hell, seems they have had to leave a lot on the table to get the big basically old fashioned air could motors to pass the EPA. I would love to get mine on the dyno at my old work place. Anyway, bye guys.

Early Guzzi EVs had an 8 bit computer. I doubt it had anywhere near the resolution of the computers used in the later EVs let alone current production.

Yes, I think your right, my 2004 Califorina Stone 1100 has a small sized MARELLI pcm with a smaller more modern wire plug on it than the other bike we have the 1998 with the SideCar, it has a big old style ecu plug setup on it. Also my 2004 has no 02 sensor feedback, the cross pipe has no bung or o2 sensor installed and my service manual says that the USA bikes never got that. So its just not turned on in the PCM I guess. Do any of you guys know about guzzidiag working with the older bikes, it should be just a simple tune file in that back, Alpha N , no AFM or Map sensor I don't think. I don't know thou. I don't know how the 1400 works but it might be Alpha N as well but with o2 feedback. I would love to talk to the tuner Beatle some time. If your reading this please PM me. I mentioned to the forum moderator that we should in any case download the new OEM updated tune from my bike so he has it to look at. Bye for now.

Reg: enjoy your smooth running 1400 and ignore the rest. i wish some days that i had mine back.

"Grisoghetto.com" , should get you to the forum that "Beetle" frequents . Peter

Has anyone actually logged afr data with one of these installed. To install one of these in a bike running a closed loop map would seem futile as the lamda input would likely just trim around it. And with an open loop map you'd be much better off modifying the main map in the specific cells that need enriching instead of just blindly tossing fuel at a wide area of the map. No one will argue that the low throttle areas of modern fi maps come lean but the proper approach is to target only the areas that need corrections by customizing the fi map. Beetle is the guy .

Hello Phil. I'm actually a retired Mechanical Engineer, I worked in Europe for TTE and Toyota F1 back in the days when Toyota had mojo. Anyway that said I have 50 years experience racing cars and even snow machines. The thinking behind the Booster Plug is very simple and works without effecting anything down stream of the Air Temp sensor. Its actually an well Engineered easy to install device that does not hurt anything on the bikes existing systems. It just allows the stock ECU to add a little more fuel to the tune via the factory air temp sensor table. That’s it simple and it works , not JUNK. Re; GuzziDag I'm not sure that is anything more than a code reader for the 1400, at least from what I have read on here, maybe others can chime in as I thought the only way to tune the 1400 is via OEM factory flash or using piggy back computers in which case I agree with you on that method as a poor method. Anyway, have a great ride, stay safe! Reg Riemer
The Challenge 'booster' plugs create, is that they trick the ECU to enrichen the fuel mixture across the rev range whether it is needed or not. This can be problematic and why a proper map with proper metering of fuel is a better option. I didn't know Beetle pulled the 1400 maps, but you are right, with out an aftermarket map, the only options are a better factory map or plug in booster or power commander type device.
Guzzi Diag is much more than just a code reader. It can do that, and can clear codes, but it is a full diagnostic suite, with ability to test and check systems, get real time 02 sensor readings, reset and adjust fuel trims, reset the TPS and a bunch of other stuff. The main issue i 'think' with the 1400's is the throttle by wire system and it's changes to the ECU, but that is all black magic to me. I have GD and use it on all my Guzzi's save the Convert. It is a great tool, free, easy to use, and highly recommended.
When paired with the Tuner Pro app, you can download a copy of your map and play with it, go through it, see how values change, etc. I am not brave enough to try to do that AND re-load it on to the bike, but it is interesting.
FWIW, I was happy with the factory map on my MGX 21, but hated the wonky handling and extra 400 lbs over my other bikes. I also just could never like the sound and feel of the 8V motors. Happy with all my 4V beasts.

I tend to agree with that. I have used Boosterplugs on a BMW F800GT and a Triumph Thruxton 865. Whilst in both cases it smoothed out the stuttering as the throttle transitions from idling to open throttle, I feel it is a bit crude as standard maps tend to be lean only where they need to be (ie the engine revs at which emissions tests are carried out). Enriching the mixture throughout the rev range doesn't make sense to me. BTW the cables etc for both bikes appears to be identical - I do wonder how bike-specific they are. The development costs for mapping precisely to all the bikes that the cables are made to suit would, I feel, be prohibitive, but what do I know..FWIW in the end I remapped my Triumph myself using a Triumph Twin Power map that matched the mods to inlet and exhaust I had made. This totally transformed the performance of the bike and was way better than what I consider to be a simplistic bodge. Just my opinion.

I used the Booster plug on my wife's BMW F800S. It was very lean on tickover and when you opened the throttle, it would bog down frequently. Took me ten minutes to fit it and the difference was like night and day. No more bogging down on take off and no more stalling the bike. I have no idea how it affected the rest of the rev range but it went well. She still has it, 40,000 miles later and now ten years since I fitted it and it still runs fine.

Never had a booster plug, but on 'other' bikes have experimented with adding a resistor inline with the oxygen sensor, with good "seat of the pants" results.
My general opinion on many of the performance "upgrades" is that while they generally do improve the performance and/or rideability - some of these modifications also have a seriously negative effect on fuel mileage. Not all, mind you. A dyno and a good tuner can make a world of difference.
Dobeck Performance used to rent standalone air/fuel ratio sensors. Maybe they still do. Fun to play with, and they can provide some good information.

i thought I would chime back in on this. I recently traded the V85 I bought when I traded in the Blu Guzz. This is a 2106 Eldorado that had 18,000 on it and now has 20,500. This bike does not feel like it needs any help with fueling at all and the mileage is about 10% better than the Blu Guzz when I traded it at about 10,000 miles. Maybe, they just have a longer break-in period. I had one of the evil surging BMW R1100 series of bikes. When it passed 25,000 miles it was running close to perfect. Euro bikes, especially larger displacement ones may just need longer break in times.

This is an old thread but I just installed a booster plug on my 2015 California 1400 Touring. So far I am very happy with the results. The idle is smoother, throttle jerkiness at low rpm is greatly improved, and the low rpm throttle response is much better. Installation is simple - you just have to lift the gas tank to get at the air box sensor.

I did this as well when I had my 1400 and also liked the results. At the time, the bike had under 5,000 miles. My 2016 had about 18,000 when I bought it and ran so well and still does at 30,000 miles that I did not think about that option this time around. Break in can really help.
Either way, such a fantastic bike, enjoy it as it is the end of an era for Guzzi with big block air cooled bikes.
