Default swapping ECUs

my JDM stock ecu is on way to J's Racing for another reflash. in the meantime, looking for a ecu so there is no down time.

wuestion for anyone that might know, if i hook up with a non JDM ecu from ebay, will it run on my JDM AP2?


many thanks for any feedback before i take the leap.

Does the JDM motor have different compression? I know gas in Japan is slightly higher octane, so you can bet it'll be tuned for 95 or whatever they have...better dump in some booster just to be safe.

you gonna have a problem if you buy a USA ecu.. they all have chipped keys. So you put a usa ecu in your car and dont have the right key the car wont start.

By the way it seems you have an 07 im not sure if you have drive by wire like we do here.. IF you do then you can only replace the ecu with ecu's with drive by wire..

Where can you get the J's ECU reflash? Or is it just the Hondata Reflash?
