Hi all,

Around 40 degrees
93
FIC2150
ROM 94171715

Idle is Up/Down then stalls

log atached

 

you need to 0 out percent timing vs temp its stupid mine was doing the same ****

 

I'm lost...and burnt. clue me in

 

Do another log showing load and map sensor KPA as well.

here ya go. dead cold/stall

I'd love to get this to work.
Other than this issue, I find my car runs a lot better on this vs 9563.
thanks

 

Under Global ignition settings "Percent Low Temp timing vs Coolant Temp" whats happening is this map is a cold start correction to pull timing to heat up the cats faster. It also makes the car die once on SD. This will fix 95% of your problem. Put all 0's in this map.

 

thanks, gave it a shot. Still ng. seems a little better though.

attached log

 

its still pulling timing big time your at 2 degrees then it drops to -13 seems to clearly be a timing/map issue. I would start by zeroing out that low coolant temp timing trim map just above the percent low temp map in ecuflash. Maybe the 9417 rom enables cold start differently.

 

Hey 3g thanks again for taking a look.
Still N/G
zeroed out low coolent temp(all - timing values)
also changed periphery bit "enable ignition retard" to 0

Not as much info on this ROM vs 9563

Gonna stick with it, look into iscv stuff.
I find my car runs so much better on 9417
throttle response, light throttle all are very smooth.

thanks again

 

I paid that guy Jstrtuning to fix mine and ended up fixing it myself after 4 failed attempts with the email flash. Trial and error and youll find the fix.

 

FYI all,

Idle Stepper Look Up modifications are changing behavior
Just some trial and error and s/b good.
