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 we're about to do a swap in my ae92 SR5 to a 16V smallport..... the wiring is about 90% the same and what isn't the same can be spliced at the sensor..... a lot of the sensors & whatnot even have the same plug style

also, this gives me the advantage of not having the AFM and running off a MAP sensor

Well... if you swap out the 4afe/7afe then save for a MAP 4AGE conversion... I guess that could work... I'll have to check this out some more... My biggest problem with building a 7AGE hybrid was the afm v.s MAP problem... I don't want to splice harnesses, cause that would just justify me to go all out and swap in a 20V or 3SGTE or something... however, if you go from Map 4afe/7afe then swap in a 4AG then convert to MAP 4AG...it may work. hmmm... *could save me from having to source out an entire parts car...*

I'll still stand by my ECU statements though... ;]

Ha! Found it.

Sorry to bump such an old post, but it's got alot of good info, and Kwanza, I was wondering what your updated thought here are? As far as I know, the emanage should actually work for a MAP conversion. I could be wrong. And as far as the 7A ecu needing alot of tuning, that's actually what I WANT to do. I really want to get my hands dirty (er... digitally) and tune my own efi. My only issue is the rev limiter on the 7a ecu. I'd feel stupid paying 300 bucks just to get the rev limit moved.

Hehe... toyotaspeed_90 has actually had great success with his set-up running the old 4AFE ECU. His ECU is modified to redline at 7800 rpms, but he hasn't had any problems with it, infact, he dynoed his engine at something like 110whp. You can e-mail him and ask a bit for more ECU detail, cause he would probably know a bit more than me. He's not active around here anymore, but he's very active elsewhere and is a good source for information regarding 4AGs. Electricals isn't my strongest. As for Greddy eManage, like I said previous, they merely interpret MAP/AFM voltage, TPS, and a few other signals then replace them according to user fuel adjustments. It should work with most models of cars, but will not work with some oddballs and won't work with a lot of older cars. Possibly modifying a 7AFE ECU to run a 7AGE 16V will work, since it's not very different from what toyotaspeed_90 did with his rolla, but it's a different story for a 7AGE 20V if that's the route you choose. I reccomend a smallport 4AG head for any n/a application as will toyotaspeed_90 (most likely).
