Stock PCM/ECM Reprogramming

Flash reprogramming is an important part of repairs and tune-ups on most 1996 and newer cars. Many times, reprogramming is the only way to repair a vehicle and eliminate false "Check Engine Soon" lights or MIL indicators, and will often fix engine and transmission problems that are not caused by mechanical issues. Vehicle manufacturers are constantly updating the firmware used in their automotive computers, and it's up to you to make sure your vehicle is running the most current firmware available. Many dealerships now use flash reprogramming as the first step for any vehicle diagnostics, and charge anywhere from $100 up to $200 for the procedure. ExaTorq is offering all reflashes for the year/make/models below for $80 plus return shipping (usually $11 via FedEx) using your PCM/ECM. Some PCMs/ECMs are available at extra cost depending upon availability; please email us.

Note: VIN required for all bench (off the vehicle) reprogramming. Some applications require additional information; see below.

We have the latest reprogramming equipment and manufacturer reflash data to allow us to update the following vehicles:
  • General Motors and Saturn
    • On-Board Programming (in vehicle):
    1996 and newer GM Powertrain/Body/Chassis flash reprogrammable controllers
    1996 and newer Saturn Powertrain/Body/Chassis flash reprogrammable controllers
    • Off-Board Programming (on bench):
    1996-2012 GM Powertrain flash reprogrammable controllers
    1996-2006 Saturn Powertrain flash reprogrammable controllers (exc. S-series)
    1984-1995 GM OBD-1 PROM/MEMCAL-based controllers

Note: For Saturn tuning, we also need to know if your Saturn is equipped with remote keyless entry (RKE), anti-lock brakes (ABS), cruise control, traction control, and air conditioning. We also need to know the tire size.

GMPP Reprogramming

We also offer genuine GMPP programming for special applications such as the supercharged Cavalier 2.2L. Your local GM house cannot do these "on the bench" and requires the vehicle to be in their service bay. There is a $75 surcharge for GMPP programming to cover ACDelco's special handling fee. Since this programming requires special provisioning from ACDelco, there is typically a 3-day turnaround time.
