High Idle (up to 3k) while stopped in gear
 

Anyone else have or have any idea why the car would idle at 3k while stopped in gear? Anything to do with ACT Prolite Flywheel or tune?

Scenario:
1. Car is fully warmed, 900rpm stable idle with LTFT and STFT basically zero
2. Drive the car around
3. Come to a stop in 1st gear with clutch fully depressed = ~3k rpm idle
4. Change gear to neutral = goes down to 900rpm idle

sounds like tune issue

You might try turning off the defrost or air-conditioning. Compressor sometimes calls for high idle.

I’m guessing you’ve never heard anyone else have a similar issue?

Oh, all my accessories are off even the heater.

BTW, I’m running ROM ZA1JA01C-114-RR91, would ZA1JB01C be better?

Check vaccuum at idle should be arround -9 psi or -20mm\Hg

Vacuum looks fine at -9.9 and fuel trims pretty much zeroe’d, but any potential benefits of using the ZA1JB01C over the ZA1JA01C on a 2013 Canadian MT?

No issues using a b01C instread of your A01C

Probably worth a try in case its a bug in thte a01C race rom patch

Yeah, I was thinking the same, btw, is the process simple or requires manual copy/paste of tables like when upgrading from RaceRom 20479 to 24256 (9.1)?

Unfortunatly ecutec dies not allow copy of tables between differnt roms even if you havd tuner version, so you have to manually copy every table in base rom accross and then repet for racerom tables. You will need racerom extension to access racerom tables.

Steve but i copy-pasted tables many many times from different roms with ecutek...

haha yes you can manually copy.


but in tuner version of ecutek you can auto copy bulk tables between roms of same calid, but not roms of different calid

Well just flashed my ROM from A01C to B01C and let it idle for a few mins, the car didn’t die but the idle is wonky. Hopefully just learning fuel trims, so will drive the car later and see how it goes.

Btw, I noticed EcuTek shows even more recent ROM as compatible like 2016, is that true?

Did you ever solve this? Having a similar issue on my FBM kit

No, I never had time to look into it further due to another project car.

I have custom tune, so was going to try a base FBM tune to see if it does the sane thing. Also, was thinking if could something with MAF settings.

What’s your specs and are you using a FBM base tune or custom?

I've been through two custom tunes, but haven't been able to resolve this issue. Have been told by my tuner it's due to instability in the maf sensor which is pretty common with the fbm kits. My issue goes away when I'm on ethanol though so it seems to be just a problem with pump gas.

I'm running their premium kit with a gtx3076r, fx400 clutch, fbm walbro 485lph pump, id1000 injectors, motoeast flex fuel kit, etc...

Mine does it on ethanol as well, btw have you tried a base FMB tune? Basically FBM base gas tune taking into account the bigger injectors and map sensor?

I have not tried their basemap. I couldn't get my car to start on the basemap so I had it towed to their shop, found out my map sensor was faulty but just went straight to the Dyno from there.

I would not recommend running a basemap for any longer than necessary. They're really only designed to get your car to the shop for a custom tune

fellas its your base idle in gear timing, set too high. return to stock timing for these tables to resolve

Had the exact same issue. The car was running fine and one day it just stalled on the freeway and wouldn't start. Car would only started with little gas and I had to keep revving the engine. But then I notice when stop and left in gear the engine rev up to 3000rpm by itself, and went back to normal idle when in neutral. The problem went away after a day or two, still kind of worry about it tho.

That does not explain why it happens out of the blue to people on a tune they've been running without issues.

Not sure thats my issue as it only happens while im moving. If I am stopped, in gear, my idle is normal.

Thanks, I will look into it in a few months when I get warmer weather over.

I also have a base FBM tune which I will test just low speed to see if it’s a tuning issue or something else
