I have just installed an evo 8 ecu in my evo 4. I am wondering if anyone else has done this and if so I would like to get some information from you. Currently EvoScan is giving me the following DTC's

P0441 Evaporative Emission Control System Incorrect Purge Flow
P0183 Fuel Temperature Sensor A Circuit High Input
P0443 Evaporative Emission Control System Purge Control Valve Circuit
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction
P0403 Exhaust Gas Recirculation Circuit Malfunction
P0340 Camshaft Position Sensor Circuit Malfunction
P0335 Crankshaft Position Sensor A Circuit Malfunction
P0118 Engine Coolant Temperature Circuit High Input
P0113 Intake Air Temperature Circuit High Input
P0102 Mass or Volume Air Flow Circuit Low Input
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input

I have FIC 850cc injectors with a Walbro fuel pump and currently is running very rich.
The Internal ID I'm using is the stock evo 8 ROM ID with the Immobilizer disabled.

If anyone could please give me some information it would be very helpful.

Thanks

 

Reflash it with a 90550001 Rom or 9653XXXX Rom. You will still have to kill a few codes. The biggest issue will be the 2 wire front 02 sensor. The easiest thing to do is run it in open loop.
