I just recently purchased a 98' Eclipse GST and I am not sure how great of a tune is on it right now so I figured I would learn about tuning and do it myself. The guy told me it has a flashable ECU, which a lot of people call an "EPROM" from what I have noticed, well I think I am still learning. And he says that there is an EPROM chip inside the ECU that is being used as the tune. So I am confused as to how this works. If I want to retune it what do I need to do and how do I do it? From what I have gathered I can get a Tactrix Cable 2.0 open port, ecuflash, and evoscan. Then tune it that way. But what do I do with this EPROM chip or whatever, is that what I put all the changes onto from my tune then I put the chip back into the ECU? Sorry I am new to this and I have done a lot of reading I just need some help.
