ECU interchangeability
 

Does anyone knows if 08 Fit's ECU interchangeable betweeen different markets. Such as USDM to CDM to JDM?
Since proflash only support USDM and CDM, I might need to get a stock USDM ECU for the proflash.
BTW, I have plugged a EP3 ECU in my GD3. It starts, redlined at 8.5K, but doesn't run very well.

Short answer is NO. Long answer you would need to change the whole dash module also. There are some threads on this from people doing engine swaps and changing to the other market dash for the "Look".

Thanks man.
What if I change the USDM cluster to with the USDM ECU?

Yep that will work. I think member kelsodeez was one of the guys that made the swap backward to use a JDM dash set. Maybe you could check his posts for it.
