Reflashing ECU




Guest WRXRallyBlue

So what do you all use to reflash your ECUs? I've looked at the main companies: Superchips, Hypertech, Jet, etc. and none offer anything promising.. You have any underground specialty tuners that are major hush-hush?

I would prefer a beginner-based approach; plug-and-play, no UTEC or anything fancy like that.

TIA

Reflashing the ECU on the Toyota 1ZZFE or 2ZZGE engines will probably not net you any appreciable performance gains - but will allow you to get stuff like the OEM security system or logic controls in the various electronic bits to work correctly.

Older Toyotas can be reprogrammed - but not by any of the vendors you mentioned. Couple of guys in the UK were doing it for awhile - but the market hasn't really turned up on these Toyotas. Basically it entails pulling the ROM off the OEM chip and copying onto separate Flash ROM - and tweak it from there.

For the WRXs and EVOs - being turbocharged and a strong market for user tuneable engine computers - much easier to get better performance curves playing around with air/fuel mix, boost, and ignition timing.

Unfortunately, Toyotas are not as easy to play around with as others manufacturers. Good Luck.
