Has anyone tried on of these?? V-Twin Boost modules from Mistral

[bikeridertim]

I know what you all are going to say oh, I would just like to know if anybody has tried one.🤷‍♂️🤷‍♂️

That would be no.

[JohninVT]

It's very similar to the FatDuc or the O2 Optimizer that Eagan sold.  It tricks the bike into running richer.  You're far better off just uploading a Beetle map for less money and better results.

Roper loves 'em!

 No experience with that particular spoofer , but last Fall we removed a very similar device from a friend's HD . Don't buy into the claims .

 beetle map , beetle map , beetle map .

Ahhhhhh......no.
It's a bodge. I'm surprised Beetle hasn't flamed it yet!

Can I ask a stupid question ?
Why would you do anything OTHER THAN install a Beetle map ?

Perhaps you do not have the computer literacy to get guzzidiag to work, even after repeated tries with several computers & different cables & reading the step-by-step threads over and over....

At least thats the boat I'm in.  I'm not going to buy one of these things, but I have bought a beetle map, cables, and I still cant get the thing into my ecu. At this point I have just accepted that my Breva will ping in hot weather, and I will never get to install the cat-eliminating crossover I paid several hundred dollars for.

I recently put one on Blu.  It works as advertised, at least on the 1400.  I didn't really notice any issues with the bike for 12,000 miles until I tried this unit.  There is not more power that I can perceive, but it just does everything so much smoother with much more precision in the throttle.  Also, I can remove it anytime if I choose.  I did not want to get into the software, so if you are not computer literate or like me, don't want to change software, I consider this a viable option.

At this point I'm assuming the plug to my ecu is faulty or something... there is now way it's a problem with the cables, guzzi diag, the laptops, and the directions... It's been tried too many times and the directions poured over too excruciatingly for it to be anything else?????

[beetle]

Mayor, it's easy to check.

Pin 2 with the blue wire is ground.
Pin 3 with the yellow/black wire goes to pin 16 of the grey connector on the ECU.

The primary issue w the O2 adjusters is that it only affects performance in the low to mid rpm range.  That's where the oxygen sensor adjusts engine performance.  They were popular before people found ways to adjust the engine map (Guzzidiag, MyECU, etc). 

Still, they are cheap and interesting to play with, but some people got into trouble with them.  Not sure how that could have happened, but ... people find a way, eh?

The O2 foolers are actually only a couple of electrical parts.  I made my own, before I moved on to adjusting the map directly.

Over a year ago I dropped 1 range colder in spark plugs in my 1100 Breva and it cured my ping issue in hot weather.

I was thinking about one of these V twin boosts for my new V85. I assumed it was something simple. About the diodes, you show three diodes but it also appears you only used a single diode in your mod. Is the single diode correct?
I was told by the dealer when I bought my 2025 that trying to modify the ECU can lock it up and even they can’t easily fix that. That the 2025s are different from the earlier bikes. I know nothing about beetle maps. Only way I have ever changed a Guzzi map successfully was with a Power Commander.

If I understand correctly, the booster works by modifying the temperature signal not the O2 sensor signal. I struggle to understand how this affects closed loop operation where the ECU is trying to maintain a stoichiometric mixture.

[michaell32]

I have seen these style of devices around for over two decades.  All they do is modify a MAP, MAF, or IAT signal to make the engine run richer everywhere at all times.  It's a silly way to try to fix a sub optimal tune.

[PeteS]

The plan is to replace the intake and exhaust in which case the stock map would not be ideal. Not sure  the 2025 ECU can be rewritten and if so how is the replacement map created? At least with a Power Commander you could tune it on a dyno with a sniffer.

I can't speak to this specific device, but I have used a similar product on a different bike before, "BoosterPlug", and it fooled the Air Temperature Sensor into thinking it was much colder than reality, which caused the bike to never go into closed loop and instead fell back to the base map ignoring the o2 sensor feedback.

Personally I wasn't a fan of it. You lose the limited auto-tuning that most stock bikes are capable of, and you're better off with a proper tune being flashed instead.

I don't know if Guzzi Diag will upload into anything new, haven't kept up on it since retirement PLUS I'll never own any new stuff.
I do think an UpMap device can load though. Pricey nowdays. I would not put a sensor modifier on my bike like that one.
I do run one that advances the signal to the injectors on my 98EV a Techlusion fuel box. All it does is add pulses to where you want and is for open loop.

The ability to load a map begs the question who created the map and what modifications were done on the bike that the map was created for.
I did some mods on my ‘76 LeMans and was able to retune by changing jets.
On my ‘98 EV I tried two chips and neither one help and both actually made it worse by lowering gas mileage by about 30%. Then when back to the stock chip and a Power Commander and it transformed the bike. Better power across the range and better gas mileage than stock.
Today choices are fewer and fewer. I can easily build Sign’s circuit for under 5 bucks. The idea of spending 135 bucks for a couple of connectors and a mystery circuit gives me pause. But given Mistral makes both the exhaust system and this V Twin Boost makes me think it might have some benefit.

Ran one with good results on my E4 (2020) V85 as does another NJ owner. Reduces popping and felt like slightly smoother fueling. He also installed a SAS block off kit which he says made another noticeable improvement in fueling. (I have the kit for sale in the Swap section).

I recently changed from the V85 to a '18 V7 Carbon Dark w/ Agostini short mufflers and will be installing the appropriate Beetle map before the riding season.

[cappisj1]

If your model can be loaded with a beetle map that is your best option hands down and worth every penny. Also don’t be intimidated to do it.

My 23 V85 mapping cant be alerted with the normal software. I bought a V Twin Boost for it. I did new headers and cat deletion at the same time. I think it made a slight difference in how it runs. It didn’t run bad before and I didn’t say OMG that’s amazing after installing it. Have ridden all day in heat, cold and rain with no negative effects to how the engine ran. I don’t baby my bikes. I will leave it on but I honestly I probably wouldn’t miss it if it was stolen off the bike and the wires hooked back up.

[sign216]

 About the diodes, you show three diodes but it also appears you only used a single diode in your mod. Is the single diode correct?

Pete

PeteS,

Yes, I used only one diode.  I show three because I had three on hand, so I photographed the set.  The diodes have specific specs, so try to use the diodes I mentioned in the text box with the photo .  Double click on a photo to enlarge it, and then the text box pops up with my tips.

However, I made that home-made 02 spoofer about 12 yrs ago, for my V7, which had a primitive ECU.  Unknown how much use it would have now a modern bike.  As you said, it's dirt cheap to make, so it's easy to try.  The hardest part is sourcing the special connectors at either end of the device.

In the end, I bought a programmable ECU, called MyECU, from Australia.  Let me change everything about the map.  See:  https://www.myecu.biz/MyECU/index.htm

If they made one for a V100, I'd probably get one, depending on the price.  This looks to be similar to the Booster Plug line of products, which I had on a 2018 Triumph Street Twin 900 and an Aprilia Dorsoduro 900 I used to have.  Pretty simple to install, and both products made the bikes run much smoother, and pull cleanly to redline.  I have the UPMAP tune on my '23 V7 Special Edition, but would be interested in something like this for my V100, which has the full Agostini big-bore exhaust, y-pipe, and Mistral muffler (dB killer installed).  Just about anything would be an improvement over the lean condition that most of the bikes are delivered with.
