[got boost?]

Hi, i noticed that in the EVO IX ROM there's 3 hi n low octane ignition maps, on monday i'll begin with the tune and i have some doubts.
I know that at normal condition, the high octane map is working and that under knock, the low octane map works, but WICH ONE OF THE 3 HIGH AND LOW MAPS DO I HAVE TO TUNE???

Thanks a lot guys.

You may wanna check out the ECUFlash subforums on EvolutionM.net within the Evo Engine Management/Tuning section. They have the Evo's tuning covered pretty well over that way.

the 2nd one. 1st is for cold start, 3rd is an "emergency mode" operation. don't take my word for it, go to forums.evolutionm.net and do a search.

If you run logging software you can log load and timing along with modifying your map for 2-byte load. when you log you will see exactly which map you are running off of. If you compare your logged data to the tables you can see exactly wich map you are running from.
