i have a map ecu 1, it only controls fueling but i can not control ignition timming, and i have noticed as long as you scale down the maf frecuency due to bigger injectors the agresivier gets the timming. I know the stock ecu has its ways to save the motor from knocking retarding ignition timming and i think one way could be making the IAT reading high tempetures. Could it work? is there any way someone can monitor the ignition on low and high tempetures? i could sound crazy but i have my iat tapped to a hole where the hooks to pull down the engine are in the cylinder head to make it read a really high tempeture, i hope someone can clarify this. To run 20psi safe i guess i need to run like10degrees less.
