 PCM Reprogramming Services - I will reprogram PCM's to remove anti-theft (VATS), disable rear oxygen sensors and other emission related components, (off road right?) change fan on and off temps, injector size, engine displacement etc.  However I won't be able to offer custom tunes for modified engines. (aftermarket cam, boost, heads etc)  $75 including return USPS shipping to do this ($150 for Gen IV Vortec). I will get you're PCM sent back out within one to three business day after I receive it.   Please remove any brackets.  I use USPS Priority Mail for all PCM shipping.   Please read to the bottom, there is a lot of important info I need to know to properly program your PCM.   Bottom of this page has shipping address and a link to PayPal for payment.

I have gotten a lot of questions if I was still doing programming, answer is YES, I have not stopped doing programming, nor do I plan to at all. This is my full time job now...  Thanks, Brendan - 10/6/2014

BASIC INFORMATION NEEDED FOR REPROGRAM

bullet

Engine Type & Year: Please let me know if PCM does not match the engine exactly.  GM used different injector sizes, fuel rail types etc across engine's and years.  It's important for best performance to know exactly what the engine is.  Also, if you plan to swap intakes from another engine (LS1 intake on a 5.3L vortec) I NEED TO KNOW THIS.  Supplying an 8 digit injector number found on side of each injector will always help insure correct flow rate is programmed into the PCM.  SPECIFY drive by wire (electronic) or drive by cable (mechanical) thorttle control.  For 99-07 4.8/5.3/6.0 Find lots of important details here: How to identify my engine

Transmission Type & Year: I can disable automatic trans diagnostics if you wish to use a TH350, TH400, 700R4 ect.  Please read on below for info about the Vehicle Speed Sensor (VSS)  Also please let me know if you will run a MANUAL transmission, this is to ensure proper idle control.

bullet

 

bullet

Rear Axle Ratio: see info below for 'Tire Size or Height'

bullet

Tire Size or Height When using electronic transmission, this info is only needed if you need a calibrated speed sensor signal output to run a stock type speedometer.  I can program the PCM in most cases to output the proper speed signal to use the stock speedometer in 88+ GM Trucks, Jeeps, etc, about anything with electronic speedo from factory.  Most of the aftermarket speedometers are programmable, and the output from the PCM does not need to be exact.

bullet

 

bullet

Remove Emissions?  (this includes EGR, AIR Injection, EVAP System, Rear Oxygen Sensors on 1996+) You may choose to keep EGR but remove the rest.  Let me know and I can keep what you want.  Typically If you say remove emissions, I remove them all.  Keep in mind, I only disable the diagnostic test the PCM performs on these components. If you keep them hooked up, they will still function, with exception to EGR.  EGR operation changes ignition timing, so If I disable it, it will not function at all.)

bullet

 

bullet

Remove Computer Controlled A/C? (this is to delete the computer controlled a/c functions.  If you have aftermarket A/C unit, or using original A/C wiring from you're vehicle, you do not need the computer controlled A/C.  If you wish to use computer controlled A/C, all sensors, switches, etc from the vehicle the engine came out of will have to be used. Also, you do not need an A/C idle up, the engine will detect the load on the engine and adjust idle controller to maintain idle speed.)

bullet

 

bullet

Is this an Engine Swap, or original Engine/Vehicle. (some things I disable in the computer has to do with the PCM communication with other devices in the original vehicle.  If PCM is staying in original vehicle, its important I know this.)

bullet

 

bullet

Mass Air Flow Sensors  (MAF can be removed from most vehicles if required, however I recommend using it if at all possible to improve drivability) LT1 vehicles had two different size mass airflow sensors. The Caprice and Camaro units are different size.  Also 98-02 Camaro/Trans Am LS1 used a 3 wire sensor.  Truck 4.8,5.3,6.0 all used a 5 wire sensor. Yet there is also a difference between Truck and VAN 4.8,5.3,6.0's. So if picking parts from different applications, keep this in mind, and LET ME KNOW, programming is different for each type of mass airflow sensor.

bullet

Cooling Fan Controls I typically enable cooling fan control with basic on/off points based on stock engine thermostat temps. It will not hurt a thing to have the control there, but not used. If you use a lower then stock thermostat, let me know and I will adjust the temperatures accordingly.

VSS - If using a non electronic trans, You should KEEP a vehicle speed sensor regardless of what transmission type you use.  The PCM needs to know if vehicle is moving.  Without the speed sensor, you can suffer from reduced fuel economy, reduced power, and idle problems.  There are a few options for speed sensors on the transmissions with cable drive output.  View this link at Dakota Digital website.  I have used Dakota Digital SEN-4160 with good success.  This is a 8000 pulse per mile sensor, that will allow cable speedometer hookup. (SEN-4160 WILL NOT WORK WITH DRIVE BY WIRE CRUISE CONTROL, You must retro-fit a higher pulse sensor if you wish to use cruise control with drive by wire.) I can program most any PCM to accept any # of speed pulses. (1996, 1997 Black Box Vortec PCM will not accept 8000 pulse input)  Also check out www.jagsthatrun.com for other speed sensor options. (Must output a SINE wave signal, or A/C Voltage)

bullet

4X4 vehicles and ELECTRONIC TRANSMISSIONS - It can get tricky with 4x4's and electronic transmissions.  GM applications with 4x4's always put the speed sensor on the OUTPUT of the transfer case.  Then there is a signal to the PCM to tell it when you are in a LOW range, so it can adjust the shift points.  (shift points are based on MPH in all GM computers) If you use a LT1 engine, there IS NOT an option for low range input, and some later LS, there IS NOT a wire input to tell PCM its in low range. Some of theses used a data signal from a transfercase control module to tell PCM its in low range. On these applications, you must have speed sensor located between the transmission and the transfer case.  There are aftermarket companies that offer an adaptor that fits the sensor in this location.  Anytime you use an electronic transmissions, must keep 40 pulse per driveshaft revolution. 

bullet

If you have a TH350, TH400, or manual transmission, 4x4 or not, then it really doesn't matter where the speed sensor is located or the # of pulses, just so PCM knows vehicle is moving, as stated above. Check Novak Conversions for information on adapting transfer cases to 4L60E and other transmissions. These adaptors include a speed sensor.  Keep in mind I need to know # of pulses and tire size/gear ratio when programming.

Email is by far the best way to contact me, it gives me a record of conversations so I can better assist with you're needs.  I will gladly give a contact phone number where I can be contacted if requested.

If you live in Canada and plan to ship a PCM to me, DO NOT ship UPS Ground. UPS decided they needed to start charging me a fee for receiving packages so I will no longer accept UPS from Canada. Also, please use 'Buy Now' below for PayPal payments from Canada, please no money orders from Canada.

$75.00 includes return shipping for PCM programming.  Please include the return shipping address inside the box, as well as contact information.  Below is a ''Buy Now'' button you can use to send a PayPal payment to me, or you can include a money order with the PCM when you send it.  Expect 1 to 3 business day turn around time.  I ship with US Postal Service Priority Mail with tracking. If you require delivery with another service, please let me know. 1-2 Day USPS Express Mail shipping is available. It may not be overnight to some zip codes. See the dropdown box below.

Thank You... -Brendan.
