Would simply leaving the TCU plugged in and in place on the car be enough to get around this CEL business?
On a slightly related side note, has anyone ever converted an OBD2 car back to OBD1 ECU/wiring/TCU to get around these issues? |
There will be sensors and such that are missed by the TCU due to the lack of an auto transmission that will result in other errors.
Changing it to OBD1 wiring ought to work fine for getting rid of the CEL, but it wont' pass emissions testing or whatever due to the lack of OBD2. Actually, the thing to do would be to build an OBD2 - OBD1 adapter, then just plug in the OBD1 ECU. I think Young Tom made one, and I'd be up for the challenge if I had an OBD2 pinout.
