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 ! Frotou |

Hello, and welcome to the forums. I think its better to get rid of any piggyback and get the Haltec or any other stand alone unit. Cuz piggy backs are just piggybacks, they always depend on your stock ECU... Thats my opinion... -------------------- Ex celica owner - just a guy from other side of the pond...

You don't know this... yet you're still brave enough to try... *laughs* I really don't know if I wanna just tell you how and what to do, or let you realize things for yourself. I mean, attempting such a project then asking such a question implies VERY little background knowledge. Kinda like performing brain surgery without know anything about human anatomy... although, since you have a Greddy-E Managment system *sarcasm*... i guess It wouldn't hurt... although that VERY expensive piggyback is quite useless unless you're building an all-out turbo boostin crazy 7A... but still its limited by the stock ECU... Anyways... you must use the 4AGE ecu. The 4AG uses different wiring, so you won't be able to directly use the 7A harness or ECU. I believe many of the sensors are different also, depending on which version of the 4AG head you use. Be it blue top, red top, black top, small port, big port, TVIS, or non-TVIS... Anyways, that answers your question. Any others, I would suggest you do your homework before taking the test...

It`s just because in all the site that refer to this hybrid they mention that the 7a or the 4a ecu can be choose (never mention that din`t work with the 7a ecu) and almost everybody who perform this setup made it in a corolla...
For 300 us for the e manage you have more than the s-afc 2 check all the feature .... it`s my opinion. I don`t want a beast of 400 hp ; this setup can provide just enough of fun for me with a little time ... Frotou |

Go with a stand alone. By the time you buy the e-manage (I know you already have it, but you can sell it), buy the harnesses, software, and other misc stuff for it...you could've bought a stand alone and not had to worry about all the other BS. Check out SDS or Autronic. They are the best values for the money. Both should fall in the $1k to 1.5k range in price. Expect several hundred (3-6) to tune it.

how big of an issue is wiring on a stand alone?
kwanza i dont mean to take away from this guys question or anything, but what style to you take? i am a brown belt in mu duk kwan/ tkd. |

I personally follow Bruce Lee's philosophy of "Having No Way as Way, Having No Limitation as Limitaion." In other words, I don't believe in styles... although I am very versed in various Japanese, Korean, and Chinese arts. Just about everything from Aikido, Karate, Shotokan, Jujitsu, Kenpo, Wing Chun, Ba Gua, Jeet Kune Do, Kickboxing, Muay Thai, Greco Roman Wrestling, etc... If not a particular style, I've studied the philosophies and theories behind them. I was originally a student of Ba Gua, which was a Chinese Military form I learned from ym father. Aside from that... heh... my Martial Art is unique only to me. It's my style. =] -------------------- "It's ok to be naked girl... I'm an artist!"

Kwanza 26 : Well, thank you for respecting me and for encouragement , you have a very good control of yourshelf
 I`ll see my budget for the stand alone; here at Quebec I can have sds and aem ems , but I think that maybe the e manage + 4age ecu will be sufficient but more complicated... Frotou |

I apologize actually, although i do note your sarcasm... ;] Our discussion has moved to private messages, so all's for you again. I'm not discouraging you, but relaying a more objective view about the project. Opposed to what many sites say and claim, this swap is not as easy as it sounds, especially when you start off with the 7AFE platform. It'd be a lot easier on a 4AGE platform... Granted, you'll learn for yourself. Again, I'm not discouraging you... in fact, I have recently just purchased a 4AGELU from a JDM AE92, the late model high-comp version. I have plans for that thing, similar to yours... although I'm still searching for a Bluetop 4AG head and a spare 7A block...;] My advantage is, this engine isn't to go into an FE harness, which requires modifications. Its to go into a GE harness... with little modification... -------------------- "It's ok to be naked girl... I'm an artist!"

I thought about doing this a while back and figured if I did I would call JET and have them upgrade my ecu to 4age specs. This would keep you from messing with wiring, and they could probably set it up a little different according to your preferance.

I look at this product and it`s very simple ! Sure it`s less complicated than swap an ecu/wiring/sensors ... can it tune an engine better than e manage ? In the system option what setup it`s better to choose = distributor or distributorless ? Someone you know (or you) have work with it ? Thank you 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 This post has been edited by toyotaspeed_90: Jan 22, 2004 - 2:04 PM |

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. -------------------- 1994 Celica GT4 WRC Edition

It will work, but it's pointless to use. The 7A ecu fuel-cuts at 6300-6400 rpms or so... and that barely taps the GE heads power potential, so using a 7AFE ECU will be exactly what you don't want to do. Why bother modifying the 7A ecu when you can just use the far superior (performance-wise) 4AG ECU? As far as the heads go, you can use either or. The blue top will have higher potential for power in stock trim, considering it has much larger ports, however, the redtop will have a nicer torque curve. That's just the head. If you want TVIS (assuming you mount a bluetop with TVIS and the 8 runner intake manifold), use a 4AG TVIS ecu. If you don't, want TVIS you can just use a non-TVIS ecu (not necessary, but you can) and plug the TVIS actuator. If you use a Redtop head, along with its 4 runner intake manifold, you will not have TVIS and will porbably have to use the non-TVIS ecu. Basically, to best utilize each versions advantages, use each's own ECU. You can actually even swap manifolds... the ideal set-up would be bluetop with with redtop's single runner intake manifold (you'll need an adaptor). The 7A ecu will not be the best suited for this swap. Also consider, 4AG ecu's are dirt cheap. Now for the block, you can use the stock internals with redtop 4AG pistons (must be redtop pistons because the blue top pistons use a different diameter pin [18mm]). The rods will need to be slightly modified to fit the 4AG pistons, because it's float pin vs. press fit. Either way, if you're going turbo, you can use the forged 4AGZ pistons (low comp) or if you're going all-motor, you use the high-comp pistons... -------------------- "It's ok to be naked girl...

For a hybrid like that, you need a Haltech E6K, an Electromotive Tec II or Tec III, on any good EMS...that's a lot of money for that hybrid...might as well spend a lot of money in the quality EMS that'll keep it living happy

yes, stock rev limiter is around 6300 or so, but it can be removed and ecu can be tuned..... luckily one of the guys who are going to help me with my swap sell tuned ecu's.....

That's not my argument here. What I'm saying is, why waste time and money modifying a 7AFE ecu when you can just use the 4AG ecu and be better off? The 7AFE ecu is in no way better than the 4AG ecu when it comes to managing this hybrid build, modified or not (in fact, if all you're doing is raising the rev limiter, it's still gonna run very economical fuel maps, and still be far inferior). Of course, fine tuning the 7A ecu (air/fuel mixtures, fuel maps, rev limiter, etc...) will make it better in the long run, but by then, just do what OBBE suggests and get a standalone. If you doubt the 4AG ecu, hear this. The 4AG is a cult tuning motor, so parts-wise, there is everything you can think up of, for it. That includes HIGHLY tuned ecu's and race-spec parts... I'll leave the rest to you... I mean, it's your piece of the pie... not mine... ;] This post has been edited by Kwanza26: Jan 23, 2004 - 12:44 AM -------------------- "It's ok to be naked girl...
