***** PLEASE NOTE: I am currently not offering remap/return service of customer supplied modules. You can purchase any new unit outright with OEM or custom calibration. *****

Welcome to our GM programming page. We offer custom ECU mapping for most GM vehicles:

All 1993+ and up LT1 cars
All 1997+ LSx cars and trucks
All 1996+ Vortec trucks
Most 1993+ V6 cars and trucks
Pre-LML 6.6L Duramax Turbo Diesel Trucks – LB7/LLY/LBZ/LMM
Most 1995+ 4-cyl cars and trucks
All 1996+ 6.5L L65/L56 Turbo Diesel Trucks including Hummer H1
Most other OBD2 GM applications, for complete list scroll down or click HERE

Your ECU or ours, professionally programmed to your specific requirements and modifications at a competitive price. Since 2005, we have programmed 1000s of ECUs for satisfied customers.

*Strictly speaking: ECU = electronic control unit / any of the following, ECM = engine control module, PCM = powertrain control module (controls both engine and trans), TCM = transmission control module.

PLEASE NOTE : We do not sell software.

PROGRAMMING OPTIONS ***:

Change VIN
Disable VATS
Change RPM or speed limiters
Speedometer correction for axle ratio or tire changes
POWER TUNE = spark timing and fuel remapped for more hp/torque
ECONOMY TUNE = improved mpg (up to +5MPG HWY for some applications)
Premium or regular octane programming
Change fan turn-on temp settings
Remap shift patterns for performance or towing
Remap shift pressures for firmer shifts
Modify TCC lockup speeds for performance or towing
Program for high stall TC
Switch automatic to manual transmission or vice versa
Compensate for displacement changes
Adjust for different fuel injectors
Adjust for larger throttle body
Program for cam changes
Delete emission functions and codes ( EGR, AIR pump, EVAP , O2s, etc.)
Program for MAFless operation = speed density mode
Delete various nuisances ( SKIP SHIFT, traction control ,etc.)
Remove or modify torque management
Delete other miscellaneous functions and trouble codes (A/C, oil level, etc.)
Nitrous, forced induction, etc...
Advanced programming options (segment swaps, stealth tunes, etc.)

*** Not every controller supports every programming option. Click HERE to download the programming order PDF form.

*** NOTE : Emissions systems may be altered/removed physically and associated electronic control functions altered/disabled for off-road applications ONLY .

For inquiries and orders PLEASE INCLUDE YOUR VIN and email

programmer @ PCMperformance.com

*** TURNAROUND = usually within 3 business days for most applications.

PRICING :

FULL CUSTOM PROGAMMING OF YOUR ECU – starting at $200 . Please scroll down for PROGRAMMING PRICE LIST for supported vehicles. Heads/cam/boost or exotic swap combos will be additional $50 fee, please contact us with details. NOTE: This is for PROGRAMMING ONLY , if you want to purchase a custom programmed ECU outright, please email for pricing.
VTD (vehicle theft deterrent) DISABLE – $200 flat fee – no other custom programming is included, ONLY antitheft system is disabled. Supported ECMs only: In some ECMs VTD cannot be disabled.
EMAIL PROGRAMMING – we send you a custom tune by email to flash into your ECU yourself (using your own licensed HPtuners, EFIlive, JET DST, etc) – same pricing with 20% discount and you don't need to remove the ECU. We do not sell the software.

PAYMENTS AND ORDERING :

Save this ORDER FORM to your PC. Fill it out and save using Adobe Reader. Email us the completed form and we will send you a Paypal request.

If you are sending in your own ECU for progamming : Save this ORDER FORM to your PC. Fill it out using Adobe Reader, print it, and send it with your ECU. We will send you a PayPal request after we receive your package. Our mailing address is on the form and below.

GUARANTEE :

If you are not 100% satisfied with the programming for any reason you may return ECU within 30 days after receipt for full refund. Or we can adjust the program for free if you so choose.

Program Updates :

Free for 60 days, $75 thereafter for minor changes (axle/tires/limiters/idle/etc). For fundamental changes such as heads/cam, engine swap, forced induction, etc., pricing varies.

SUPPORTED VEHICLES :

The price list below custom programming ONLY for factory/bolton/swap applications. Internal engine modifications (cams/heads/strokers/etc) and (non-factory) forced induction are +$50 . Due to time constraints and involvement with other projects I am currently not offering remap/return service of customer supplied modules. You can purchase any new unit outright with OEM or custom calibration.

The cost of complete custom programmed ECU purchased outright – you are buying a new plug and play unit with programming included – varies depending on the controller type, from T42 = $75 and up additional to the programming below. Please inquire for pricing.

We do not need your old unit (we do not stock/sell used modules). If you only want an OEM VIN programmed replacement unit or VATS disabled only, please inquire for a discounted price. The list is outdated and incomplete – we do stock and program Gen 5 SIDI E98 controllers, etc. We do bench flash internal TCMs (T43/T76), but they are a nuisance to remove and install so unless you are a replacing the controller there are probably better options.
