Hello to everyone !
I have some issues with tuning Gen IV ecu what i can?t solve.
Can someone check the file and give some help.
First thing is startups, i get it start cold ok, but warm or hot start is hell... Starts and stalls if i dont hold foot on pedal.
Biggest start/stall problem is when i stop 5-10min and try to restart with hot engine.
I did get it better but now throttle hangs in gear at 1100rpm and it still starts and stalls half the start times.
The over/under spark i cant use because emissions(Need to stay 16degrees) or HC is high.
So i think i need to try tune hot start with airfow.
Second problem is with new injectors 1000cc(@3bar), it runs rich even if i max out flow tables and voltage correction (pulling out -25stft and -25ltft / afr is 10-12:1
Injectors are flow mached de-capped set.
Third broblem is TCC hounting on low APP/TPS
Converter is 2500rpm circleD billet 3-plate.
Car is 2010 5gen camaro with L99 with:
-DSS Racing forged pistons
-Total seal gapless rings
-Edelbrock e-force kit with 3.25 pulley
-Comp cams 277LCBHR14 (227/243@50)
-ZL1 Fuel pump
-E85 Flex fuel
