Hi,

Does anyone know if the US and UK MY01 ECUs are exactly the same? Would they be mapped differently for different fuels etc?

Trini

 

Great question- have no answer.

 

No answers here too, but i think UK and US must be same but JDM is different, not sure.

 

OK, so if one has to replace the ECU, waht esle hase to be done regarding the immobiliozer system? Some sought of key reprogramming has to be done?

Dead ECU

 

If your car has the immobilizer system, you'll need to program your existing keys to the new PCM. This has to be done at a dealer.

 

is there a difference betweem jdm and usdm?

 

Yes, The JDM cars have a top speed limiter and no Immobilizer.

 

Don't know about the others, but Aus S2000s don't have OBDII. I don't know if UK ones do or not, and have never been able to ascertain whether the difference is in the ECU or just a case of not having the supporting hardware (OBDII plug back to ECU).
