Anyone have any information about tuning for E85 on OBD1 PCMs? I'm considering doing an E85 conversion to my 94 LT1, which is currently down and requires a full rebuild. I've found quite a bit of info in regard to parts and the differences between gas and E85, but tuning for OBD1 seems a bit lacking.

Would it be possible to use the OBD1 PCM for an E85 conversion? The stoich for E85 is 9.7 versus 14.7 for gas. I know it can be done with OBD2. I haven't been able to find much in regard to OBD1, though. Any info would be greatly appreciated.
