I found this on the web, but I ain't got a lot of smarts on ECU's ... anybody know anything about this company http://www.coe.uncc.edu/~mdkeena/ecu/

check this forum for people selling the modified ECU's:
http://forum.pgmfi.org/viewforum.php?f=3

i never heard of that person but modifing the ECU to allow for chip swapping and datalogging is fairly easy


I know the chap that runs it - Mike Keena....he knows muchos about tuning Hondas. I actually didn't realise he did this until racerman50 told me in an earlier post. Sent Mike an email, hoping to hear soon. Will post results.

The only way you could get the Hondata system to work on a OBD-0 CRX is by replacing the stock PM6 ecu with a PR3 or PW0 ecu. The PR3 and PW0 came from the JDM versions of the CRX that came with the B16A engine. The only differences between the two engines would be the VTEC module and the additional camshaft. It is possible to run the D16A6 off the PR3/PW0 ECU but you have to turn off the VTEC, turn off the knock sensor, and mofiy the timing and fuel curves, which one would do to tune the car anway. I dont know how legal this would be since your replacing the ECU with a JDM version, but its not any benefit then to programming using the stock PM6.
