In the Honda Community there are many companies and individuals that make ECU harness adapter plugs. For example you were putting an Type R motor into an OBD II car(civic for instance) but you wanted to use an OBD I computer. Well the sockets on the 2 computers are different so you can't just plug in the OBD I computer. To solve this they make a small harness so the OBD II harness(under the dash) plugs into the new socketed harness and then the other end will plug into the OBD I computer.
Now lets transfer that to the DSM world. Could we do this in the DSM community? This of course would be for the 2nd Gen cars. Could a small adapter be made so we could plug in a 1st Gen ECU so it will match the 6 bolt engine swap? Maybe this would help with the CELs the 2nd Gen ECU sometimes throws, plus eliminating the cam angle sensor you would have to add. Maybe I'm missing something here but shouldn't it work?
 
No it won't. It won't eliminate the need for a cam angle sensor because the cam angle sensor also acts as the crank angle sensor. Why try switching to a 1G ECU and then get rid of the piece that makes a 6-bolt swap without retaining the 2G sensors possible?
 
wow, I have no clue what I was typing late last night(In dream land). Forget what I said about eliminating the CAS(insert smilie with gun to head here..hahaha). I understand that one of the reasons that the 2g ECU throws a code could be that it's looking for the accuracy of the crank angle sensor over the 1G CAS. "A simulated crank signal from the CAS may not be accurate enough for some ECU's"(quoted from RRE)
I meant to say. Would the adapter work so you could use the 1G ECU to eliminate the codes thrown(sometimes) by the 2G ECU?
Or am I in la la land again:p
