How To: Chipping Honda ECU's

[bmgjet]

Manual ones can be chipped, Auto ones cant be.
Ones after 95 cant be chipped either.

my ecu is a manual and its from a 95 vtir. I've got the hondata already in a PR4 ECU, all I want to do is install it in the P72. Is that possible and how can I do it. Thanks.

Thanks for that. I've got the S300 and according to my ECU being the square shape, im meant to run the S300j. Can I install the S300 in my ECU, providing I extend the DATA LOGGING connection to reach the S300?

Haven't tried it myself, But it should work since that's the only difference along with the JDM ecu not controlling the purge control valve.

Does the AUD Vtir come out with the square ECU, or the rectangle shape ECU? I'm trying to work out if the guy I bought my 95 VTIR off has changed the ECU for a square JDM one before selling me the car. How can I find out what ECU I've got? Whether its JDM or AUD? I know that its a P72. Cheers..

No idea, Not in AU so havnt dealt with any AUD models of them before.
But get the full code off the sticker on the side.
Then look in the PGMFI bin page in the Wiki and find the one that matches and it will say where its from.
