can you elaborate on this??MustGoFastR said:.......It is a falacy that the ECM gradually de-tunes mods and you don't need to reset when adding new mods as long as you take it easy for a few days and let it adjust.
It DOES work; I've done it myself on my FX. There are a couple more steps after the ones you have listed (shown on the Technosquare page) to reset the ECM memory, but if you can't get it to blink to begin with, then your timing is off. Keep trying and review the procedures again; it took me several tries to get it right.WeGaFX said:MGFR, that's the one that I tried. It is also in the FX service manual. However it seems to be a reset of ECU if the MIL light is on (ECU has some trouble code). I have tried (with no success) performing this procedure. Attached is the timing sequence from the service manual. After the 5 accelerator pedal cycles and the 7 sec pause and 10 sec FT the MIR light should start blinking. This is where I got nothing. Any thoughts. As I add mods I would like to always start from the same point, also I would like to know just how the system works.
Well, it started on the Z forums when people would add an intake or exhaust, dyno the car immediately after the mod and register certain gains, then dyno the car again after a period of time; in some cases, the gains were lower (sometimes much lower) than they had been right after the mod was installed. This led to the rumor that the ECM, while attempting to maintain the engine's operation within a certain set of parameters, effectively negated bolt-on mods once it had time to adjust.esemes said:
