Hi Everybody

I just join the Honda-Tech.com and this us my first time come here so i got some questions.

What is different Jdm Ecu and Ameica Ecu

37820-p73-013
37820-p73-023
37820-p73-a03

so i would like to know is that 3 ECU any different proformace ?

Tks

 

- the JDM ecu's are mapped differently because of better premium fuels offered in Japan
- the JDM ecu's have a speed limiter of somewhere between 180-200kmh (US ecu's are not speed limited)
- the JDM ecu's do not look for crank fluctuation sensor, secondary o2 sensor, vtec oil pressure sensor, fuel tank pressure sensor

 

ok thank you very much

so the JDM ECU is better or America ECU is better ? ( i mean proformce)

NO, they seem to be almost identical w/ USDM being slightly better but that could be due to useage of 91 octane fuel. . from personal expirance on my ITR and my EG w/ R motor, USDM seemed better but thats only butt dyno!

 

they are about the same.

maybe a little more aggressive on the JDM ecu since it is mapped for 11:1 compression, higher flowing header, slightly more agressive cams and better gasoline.
