Mapping the California 1400 is ready now

[JohninVT]

Lol John, you are a speed demon for sure😂

A little bit...lol.  The fact it's geared the way it is and has a hard rev limiter is why I half jokingly asked Beetle if a map would produce a 140mph Cali earlier in this thread.  If it would pull to redline it would go about 140mph.  My speedo is off about 3mph at 80 so in reality it would "only" be 135-ish but that's still ridiculously fast for a cruiser with bags and a windshield.

I think it would be hilarious to bring it to Loring for the speed trials and run it without removing the bags or windshield.

I need a victim volunteer to run to the rev limit in 2nd & 3rd gear, and log it with GuzziDiag. I think I've found the limit in the map, but need data to confirm.

I believe Johns your man Mark, he'll try anything for the shear adrenaline rush if it involves speed it seems😂

[beetle]

Well..I compared the same part of the map with one from an Aprilia Tuono, Seems I might have found max RPM per input gear. I may have to search for max torque demand. Anyway, I can tweak a map if someone would like to be a guinea pig?

[JohninVT]

I'd do it for you in a heartbeat but we have 6" of fresh snow and it's 31 degrees.

[beetle]

We'll just have to wait then.

We'll just have to wait then.

I'm planning to get my stock Cali 1400 out of storage at the end of this month.  I can volunteer to be the guinea pig then.

Lol, we went through this for months last winter with the CalVin, trying to get rides in to evaluate the changes, in between snow and rain and I don't think Lisa's nerves can handle another adventure with my 1400😂

[Kiwi Dave]

I thought it was 6,500 rpm.

Can't be.  I've seen much higher than that.  i gotta do a test tomorrow.

Well, I'm wrong again.  I took my Cali out today to warm up the oil for a change.  Wound the throttle in 3rd gear.  Revs climbed quickly to 7,000 rpm and then slowly plateau'd at 7,500 rpm.  It was not abrupt like the CARC bikes, instead a much gentler limit.

This was on my Cali 1400 that has the ECU tweaked, but I'm guessing this feature hasn't been modified.  Still willing to be Beetle's guinea pig with my stock one when it returns into service.

[beetle]

The stock maps have a 7220 RPM limit in 3rd.

In what way is your ECU tweaked, if I may ask?

It's a GuzziTech version, I purchased the development bike off Todd a few years ago.  It's running a Power Commander, which I have no problem with, despite your distaste for such technology.

I have an open mind about all technology, back then there were no Beetle maps, and I don't even know if you are doing anything significant for the Cali 1400 yet.  But I'm happy with the Beetle map on my Griso 1200SE, horses for courses.  I also have power commanders on three 1200 Sports (2 with autotune) and an early version on a V11 Le Mans.

I also have an unmolested Cali 1400, which is what I was offering to use for your guinea pig test.

[beetle]

No need to confess. "It has a Power Commander" would have sufficed.

RPM not affected then.

[Tourville]

Interested if any further RPM limiter knowledge has been generated.

The 1400 with the right cams / springs should break 10,000 rpm .

My old R90 BMW shifted @ 8.5k only because the oil pump pulled
vacuum holes in the Oil above that.

There's alot left on the Table with having that ECM taper off power
@ 7k .

Looking at DIYautotuning Megasquirt but would prefer a corrected
version of the Factory Unit if possible .. planning Turbo as well.

VNT / VGT variable vane Turbos for VW 1.5 L gasoline engines
have Electronically Controlled variable position Vanes.

RPM range is same as Guzzi.

These can be had off DE eBay around $400.00 US.

Here's one Model:

05E145701E Turbocharger  1.5-TSi-DACA-VW-Golf-Sportsvan

They'll be USA bound next year from what I've read.
Been in European Production a few years now.

These are Oil Cooled, not Water Cooled housings.

No stand alone controllers available as yet, not rocket science tho.

I've an eMail into DIYautotune for a controller.

Really need a way out of RPM limiting in the Factory ECM.

[JohninVT]

I think the piston speed would be too high at 10k.  I also think turbocharging and raising the rev limiter to 10k on an oil/air-cooled engine will turn it into a Palestinian alarm clock. 

I’ve messed around with turbos a little.  You’d have some trouble building boost without lag and even running 5-6psi you’ll have some cooling issues on a 1400.

[Tourville]

DeStroke could be 1.2mm running 1100 crankshaft.

Turbos.. there's a new kid in town:

Electronically controlled variable vane 1.5L Turbo
VW in Europe has mass produced for their EVO 1.5L
engine.

Make Boost just off idle.

Vanes will self adjust to maintain dialed in
Boost as RPM climbs.

This Turbo approach is the game changer for
future engines worldwide



.

Smaller, Lighter & High Output

As it's in use in Europe & not USA as yet, talk is 2021 in a 1.8 config
finding signaling paths is the key for a stand alone controller.

That info is in the UK as yet.

[beetle]

DeStroke could be 1.2mm running 1100 crankshaft.

Er..no. May as well try using the crank out of a Panigale. Not going to fit, no matter how big your hammer is.

[Tourville]

Perhaps off-set grinding a 1200 crankshaft to 80mm then.
Lighter crankshaft throw - reduced rod weight

A Corvette can spin 9k with their 92mm stroke ,
81.2mm @9k shouldn't see shrapnel ..

[pauldaytona]

The rollers don't like 10k that much I think. Getting more power out of a cali 1400 first needs head work. I think the turbo from the sportsvan is huge compared to a cali.
 

[Tourville]

You're right about high RPM & Roller Lifters.

Dual Valve Spring rates will need to be raised
to maintain roller to lobe contact.

Roller Lifters development flourished
 for high RPM
drag racing .. Isky had alot to do with
moving Roller Cam development along.

Roller cam profiles carry greater detail
& more accurate actuation than flat tappets
& as long as valve springs keep the Roller
Lifter from bouncing off the Cam Lobe, RPM
Ceiling is pretty much unlimited.

Flat tappets do better at low mid RPM levels as
Rollers tend to scrub lobes during low RPM
stop 'n start contact.

Isky had a product called REV CAPS which had a
valve spring around the regular valve spring with
a cap attached covering top of valve stem .. added
500+ RPM - the newer metallurgical mixes & dual
spring rates eclipsed them.



Bench Flowing a pair of heads i$ 6oo to 1200 done by
someone like San Jose BMW's Chris .. gorgeous to see.

The Turbo is a 1.5 Liter unit .. Cali 1.4 liter would have
almost instantaneous Boost from
the 96 kW TSI evo engine turbocharger with it's variable turbine geometry (VTG)

Here's some VTG info .. it's Old VTG tech as the vanes are now
controlled on the fresh air compressor electronically doing away
with re circulation of exhaust gas control on the hot side.

http://www.turbos.borgwarner.com/en/products/vtg.aspx


I may skip Turbo 'n  go with 11.5 to 1 JE Pistons, lighten / balance Clutch..
better valve springs & custom Breva style
dual exhaust.. it's saner.

 Get the Maps done with
RPM ceiling removed for new cam profiles & call it even.

Hudson Valley NY is hills 'n mountains &
a big air/oil cooled Twin could heat soak
under a Turbo.

It'd be fun for awhile tho

Mark,

If I'm reading this correct, you need people to send you  a copy of their map to be updated?

What are the changes to the mapping profiles for the 1400 other than removing the exhaust brake sound on decel?  I'll be sending a copy of an MGX map. I plan to do a 3k valve adjust, then load the map and reset the tps and trims.

 Do you recommend .10 and .15 as with your 1200 maps, or stick with the .15 and .20 Guzzi recommended?

I'm sure it was answered, but redline is basically 7k, with a smooth drop of power until 7500 where it just sits and acts strangled. I like the smooth power cut as opposed to the 'sumptin broke' fuel cut off, but would love to see it pull strong to 7.5-8K. One of the benefits of ride by wire.

I'm running the Ago Nero exhaust with db killers out. I just finished an 1100 mile tour with them in and while they sound good, there is an odd whistle pfft with them in. I may also try to shorten them, but not thrilled with the idea.

[beetle]

Correct. That guarantees compatibility.

Map components changes are:

Main fuel tables
Torque demand correction tables
Ignition maps
Target idle
Max RPM -> 8000
Temperature correction tables.


I recommend 0.1 & 0.15 for valves. The cam box is identical to the roller 1200's, and is affected by heat in exactly the same way.
