4AGE 16v with 20v ITB Problems..... PLEASE HELP!!!!!!!!
Hello people,
I have just completed my 4age ITB setup. I am using the AE92 wiring harness and MAP ECU with a high comp 4age engine and a big port head. I have the T3 intake manifold with a set of Silvertop 20v throttle bodies. I swapped the outside wires in my TPS so the voltage readings would be reversed to match what the ECU should read (20v ITBs work in reverse to the stock AE92/ AE86 TPS setup).

I am having problems revving the car out. It usually bogs down but I was told that it could be caused by the plugs fouling form too much gas at idle. When the car eventually revs out it reaches 5500 rpm and there is some sort of limiter. It doesnt rev past that point. Does anyone know why or what the solution is?

The car also has a very lumpy idle. The engine has in 288 HKS cams with 8.1mm lift. I am going to try playing with the fuelling map on the ultimate to see if i can resolve the bogging down issue.

I have read that the 5500 rpm limit has something to do with the ignitor/ ecu/ dizzy setup. CAn anyone shed any light?

Thanks.
