7AGTE, which ecu use ... Options

[frotou]

I`m in progress to complete a 7agte in my ST 1994.(Don`t try to change my mind , there a lot of work there is made now). 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 !

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
