S300 in P72 US ECU - Prelude H22A JDM - Help PLZ!!

Post by Masta_Cutz »

Hi guys,

finally bought myself a Hondata, came supplied in a P28 which is all good, car runs and the hondata logs so that's great.

Obviously I'm missing IAB support so i've got a virgin P72 US ecu sitting next to me ready to be penetrated with the S300.

Only issue I have is that the P72 knock board has different harmonics so I want to swap it for the P13 JDM knock board in my current ECU.

Here's the question... is it simply a case of de-soldering the knock board from my P13 JDM and installing straight into the P72 US or is there more involved???

I need to get the P72 set up as I want it rolling roaded immediately after installation so it's running perfect.

Can anyone help?

thanks a lot!

I have tried soldering P13 knock board into P30 ECU, and was getting unknown CEL 24. Maybe my P13 knock board was fried or maybe they are "incompatible". I'm going to try to solder the board into JDM P72.

Would using a GS-R knock sensor in your block make any difference?

the GSR knock sensor is not tuned to the harmonics of the H22A therefore the P72 knockboard is useless on my engine.

Anyone got any ideas on this one? gonna be prepping the P72 tomorrow so it would be nice to know exactly what's what.

Thanks
