With the advice of this BB, I sent the MEFI-3 ECM off to Mark at Precision Marine to have the calibration reprogrammed to match my engine. Mark has been very helpful and reasonable. However, the eBay seller who sold me the ECM failed to tell me it had a bad injector driver and is worthless.

Does anybody know where i can come up with a MEFI-3?
