That's really nice. I really need to learn how to mess and adjust my idle in aem tuner. Or I need to go back to my tuner. My car has been tuned by Sean church with these new FIC 1650cc injectors and I idle in the 12s and 13s. Still way better and the car drives perfect compared to 2000cc injectors.

Try to find that spec sheet you got with your injectors and confirm the dead times they gave you. Your map had waay different numbers than mine and that could certainly throw your idle off. I can try to make a few changes to yours to see if it'll help.

This is from your map:


And here are mine:

Would you care to post your idle tab screenshot? Curious of how you have yours setup.

I appreciate that alot. Your Ign vs Rpm part is fairly aggressive. Idle part of my map is set I think @ 8 degrees, and yours is +\- up to 30 degrees?

Mine looks starts at 10 and stays flat there until about -75 tapers through zero, and this is the mirror opposite through 75, back to -10 and stays flat.


Is + and - up to 30 degrees ok to do, not seen it done like that.
