Engine Ecu

Ecu

Hey guys, I know this question might have been answered before, But i cant seem to find an answer. I have a 99 corolla CE, and was wondering if there was a way to reprogram the ECU or upgrade it somehow, and what steps must be taken to do it. thanks

to reprogram the ECU, disconnect the negative battery terminal, not the positive.
upgrade it, i dunno bout that.

so i need the initial piggy back add on as well as software? how exactly do you program the piggy back? oh and whats f/i? sorry with so many questions.

what would that do? wouldnt it just reset everything like my deck and my clock? its ok, cause I found out the best way to go is with a piggy back. thanks though

oh definatly the way to go if you want to program it is to get piggy back. I have e-manage because I am going f/i. I just got my clone cable, and I've got the software ready. As a matter of fact, I am going data logging tonight; between that, and other peoples' maps you should be able to tune it fairly easy. If you don't plan on going f/i, then I wouldn't go as drastic as e-manage, I would go S-AFC II. Even if you are going f/i you can still go with the S-AFC II, you will just need a FMU [votech]
