HI guy

this is my first post. I got a evo IX GSR and having some problem with it now. hope you guy give me some idea.

The 9 is using the Hydra ems ecu 2.5 version now, the ecu is for evo 4-8, it cannot run the mivec becoz of old version. this is not what i buy, the last owner changed it.

and now the car is running 20g turbo but with stock injector. i m thinking change to 1000cc injector to give more power. however, i want some advice on buying a second hand stock ecu or some aftermarket ecu. coz if i get the stock ecu i hv to get back the Maf sensor and loom which i dun have, and it cost for fixing the code for immobilizer.

 

if you want to switch to the stock evo 9 ecu it is easy enough to disable the immobilizer. with the stock ecu you don't necessarily need to put back the maf. you could just simply go speed density. if you are worried with regards to tuning there are a lot of reputable etuners here that could help you.

 

What is the difference between LHD AND RHD evo 9 ecu
The part number is not the same
RHD is 1860A501
LHD is 1860A465

 

The ECU map will be different but the hardware should be the same.
