Our PCM's (Powertrain Control Module) may be either rebuilt units, or good (fully tested) used units. When we buy cores from wholesalers, some of them are perfectly good working units. These are sold with the same warranty as our rebuilt units.
The main cause of PCM failure continues to be people pulling out their chips with the key on / engine running, which almost always fries the microprocessor and the chip. Occasionally it's the EEPROM that can fail.
3 Year Unlimited Mileage Warranty!
Note: PCM's are pre-programmed and ready to install. When installing a performance chip, rear terminals are pre-cleaned and should not require any additional cleaning.
We require that you send a matching core.
