Hello, Merry Christmas, and Happy Holidays; I am currently developing software to tune the pt3/pt6 ecu's found in the 90-93 accords, and would like someone to help figure out how to add vtec circuitry to these ecu's. I believe the IAB parts are located at D13, which on a pt3 (without iab's, these components are missing). On both boards, there is a spot to the right D15 that I believe may hold the key to adding vtec circuitry to these ecu's (to the left of D13 I believe is EGR). If someone would please take a look into it, it would be greatly appreciated.
All the documentation I've generated/collected in regards to these ecu's so far can be found here:
Wiki setup for any developers/contributers to post information on in a more organized fashon then a bb.
Thanks in advance,
