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 |

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...
