I'm looking to run a high-compression 22RE racing engine off a GM 7727/7730 ECU (following in this guy's example, minus the turbo), but where I live, we don't have junkyards like pick-a-part where you can go explore, and I'm not sure what I need. I'm looking for part numbers/applications for memcals from MPFI 4-cylinders that will work with the 7730, so I can hunt one down on ebay. Any help would be greatly appreciated!
You're probably looking for a memcal with $58A mask code out of a 1227749 ecm. The 7749 is almost interchangable with the 7730. Custom tuning and probably other modifications are required.
7749 Engine Applications:
1987-90 2.0 OHC L4 PFI turbo “M” LT3
1987-88 2.3 DOHC L4 PFI “D” LD2
MEMCAL IDs:
“M”: AFDZ, ALBK, AMUW, AUWS,
“D”: AMDB, AMDD, AMDF, ARPZ,

Thanks for the info, and the link. I'm planning to flash it with Code 59 anyways, so I'm not sure if it matters what codemask was on it originally, AFAIK the only reason I need a 4 cylinder memcal is for limp mode and something to do with ignition timing. Can I put a memcal from a 1228707 or 1228708 into a 7730? Also, can fuel/timing info from a rom designed for Megasquirt be used with TunerPro/GM ECUs?
There's more to the memcal then just LHM when it comes to fueling...
