OBD2 Integra ECU?

[jlucas]

Can anything be done within the rules? All the options I'm seeing invovle swapping to the OBD1 (larger case) ECU with an adapter, which I read as being not legal.

Which car? Luckly for me, all 3 of the GSR ECUs are the same size.

[jlucas]

Didn't have anything in particular in mind but since we have an OBD2 Interga LS and Prelude (non-SH), I guess those would be the most relavant.

[SPiFF]

With update and backdate does it really matter if the ECUs are different size?

[jlucas]

Well I guess that helps with the Integra but not the Prelude.

Wouldn't you have to swap the engine harness too (due to the couplers, on the progamable OBD1 ECUs)?

Donno about the 'Lude, but the whole "stock housing" rule is bone headed. We have an open ECU rule anyway. The housing clause just causes these kinds of problems. Any ECU which connects to the stock harness is much more sane. Anyway .....

Hondata makes an OBD1 P28 with OBD2a connectors to get around the lame rules.
