Curious as to what I need to I guess convert my OBD1 ecu to OBD2 so I can connect and tune live. Rn my ecu has a ST chip in it with a tune that has simple stuff like launch control and what not. But instead of buying the chip burner and doing it all the old school way how can I convert it? Anyone have any good recommendations ? Im not really new to the mechanic side of things but as far as tuning goes I’ve watched it done but never done it. Especially converting old Honda ecu lol… but if need to know what ecu I’m currently running I’ll add that. Thanks In advance.

 

tuning an OBD2 ecu is pretty much impossible unless it's like a K series ECU (which is irrelevant in your case).

 

Ummm... you ditch the chip tuning idea and install a Hondata S300 in the ECU that you have. This way, you can tune live.
