I have a GREDDY E MANAGE + PROFEC e01 as piggyback but I would like to know if I can use my 7afe ecu or I NEED the 4age ecu for this setup ? There is somebody who try this in a 6th gen celica ? Thank you for help , and what a NICE site on the 6th gen ! Frotou

actually you DON'T have to get a 4a-ge ecu or harness.... since you're doing a conversion, you should already have a donor motor (4a-ge) and should be able to get any sensors you need from it.... you can splice into the 7a-fe wiring..

but since the GE head will rev much higher, you will need the rev limiter removed and fuel/air curves changed a bit....

we're doing this on my 90 corolla (4a-fe to 4a-ge 16V, map sensored 4a-fe ecu) but will be running an aftermarket adjustable FPR and full MSD ignition...

you will also need an aftermarket ignition.... the 4a-ge has an external coil unlike the 4/7a-fe.... the wiring on the 4a-fe ecu is slightly different here... using a universal system (like MSD) takes care of it

.... forgot to mention, the 4age head you need to use is one from a redtop if you plan on using the stock ecu..... the bluetop 4a-ge has t-vis... you can not hook up the t-vis, but you'll be robbed of power

yeah, except the 7afe ecu sucks, and im pretty sure it would be able to run the apropriate ignition and fuel maps once you swap on a performance head.
