I've got a $4,500 NA build coming up but there is one thing I need to check off my list before I start buying the parts for my 2ZZ.
I need a way to tune my OEM ECU. I've done some searching and nothing has really been coming up the way I like. I've been searching for a system similar to that of the Hondata system for the Honda K series of engines; a reflashing and tuning tool. Does something like that exist for the 2ZZ ECU?
I don't want to program an entirely new ECU and I'd like to have a system that allows me to mess with a few paramaters other than just the fuel trim and ignition timing. I'm aiming for 9500rpm redline in this build
Does anyone know of a reflashing system for the 2ZZ ECU?
