Arrow I will pay you to fix my cold start issue. Fic 1150/8859

I hate struggling with this, ive tried nearly everything and I cant get this stupid IX to idle right immediately after engaging. Warm starts are fine, and cold starts are fine when temps are above 32* SO- first one who fixes it will get $50

rom - 88590715

fuel - 93

symptoms -

Car fires, idle climbs to 1400 or so, then slowly works its way down to 500 with AFR in the 10's. SOMETIMES I can let it putt for a few seconds, then restart and it catches the IAC fine and does its thing (idle at 1400 during warmup).

Stuff Ive done -

BISS SAS - set to 800 (I think)
MAF comp - lowered the **** and it didnt work.
MIN temp for closed loop - Lowered the **** and it didnt work
Desired ISCV - raised, lowered, everything in between. **** didnt work.

WTF is happening? If I dont get this right, im going back to stock injectors. My X fires and idles just fine with FIC 1100s, and so did my 8 with these exact injectors. I feel like stabbing something

Mess with your injector scaling. If they're high impedance make sure you eliminate the resistor box.

I wouldn't mess with the MAF and min temp settings put them back to stock.

Could you try that map and log the following entries?

RPM
TPS
Load
Timing
AFR
Coolant temp
STFT
LTFT-low
LTFT-mid
ISCV % demand
ISC Steps
target idle rpm

also if you going full rich then it dies.... your flooding it. the more you try and crank and it wont fire and the WB reads full rich, the more fuel your letting get down into your oil. i would pull a plug and make sure it isnt saturated in fuel.

looks like im still having problems. Car fires fine, but it runs extremely rich, bogs for a few seconds rich, RPM jumps up to 1700 while still pig rich, then it finally stalls when the engine sees how rich it is and cuts fuel.

ok I think I fixed it by setting my MAF vs COOLANT TEMP to the values found here https://www.evolutionm.net/forums/ec...-9417-rom.html

nope still ****ed.

copied my injector scaling and latency AND IPW adder values over to my OG rom that came with the car (that worked perfect with my stock injectors) and still a **** cold start.

fires, and idles real low and real lean. Sometimes gets up to 1500 rpm for a second while rich, then drops when the fuel is cut and leans out and stalls
