We are modifying ECMs for low impedance injectors, we have the parts in stock in good quanity. Please send in only known good ECMs only as we modify YOUR ECM. There is lots of junk out there, please check the following:

Main connectors, no rust, corrosion, slime, please. We often see these water damaged from heater core failure or leaky windshields / antenna

General, remanufactured units can be a real problem, quality is
inconsistent. In doubt? Buy a clean used ECM from one of the 'recyclers', a non-reman unit preferably (if you must go reman go to a GM dealer). Put it in the car and drive it around for a couple days. Ensure no codes get set, and that the A/C, Scantool data, Fans, etc all work correctly and there is no 'wierdness'. Then send it in for modification.

This requires a little planning, but is WELL WORTH IT. The quality of some of the 'remanufactured' ECM's is horrible. Clean, virgin ECM's are a much better solution. These ECM's are very plentiful, there is no reason to use junky ones.
