Hi All,
I notice a lot of people on here with an electronics background and a lot of threads dedicated to fooling the ECU.
I wonder has anyone changed the ECU prom values to change the way the ECU operates under different conditions so that they dont have to fool the ECU. I have heard of many people changing their ECU values to increase performance so i know its possible and relatively common.

I am particularly interested if anyone can point me toward a eeprom value mapping for particularly a mazda 626 91 model or if anyone has "decoded" their cars eeprom to understand what the different values do.
