    A PSI PCM is the perfect complement to your PSI harness as they are tuned according to your specifications to match your setup. With PSI’s 2 decades of tuning experience, we ensure your PCM is programmed with the appropriate operating system for your engine and transmission combination along with calibrating it for the appropriate displacement, mass air flow sensor use, injector style and flow rate, throttle body type, tire size and gear ratio. Your PCM will be tuned to operate as closely to an OEM tune as possible based on your specific application; all builds are different and the same engine build between different vehicles, in different locations, being used for different purposes, will require a custom tune to get the vehicle dialed in for your particular setup. Because of this our computers are not locked so the included base tune can be adjusted to reach the goals you’re trying to achieve.

    PSI programming includes the following:

    • Correct Operating System for your Engine and Transmission Combination
    • Removal of Vehicle Anti-Theft System (VATS)
    • Lowering of Cooling Fan Temperatures (Fan #1 ON at 195F, Fan #2 ON at 205F)
    • MAF Sensor
    • Fuel Injector Flow Rate
    • MAP Sensor
    • Throttle Body Used
    • Alternator Settings (2 Pin or 4 Pin)
    • Updates for Correct Tire Size and Gear Ratio

    WARNING: The installed tune is a base/startup tune, mirroring a factory OEM tune based on the options selected in your order. The tune will remove the VATS (Vehicle Anti-Theft System), bypass VVT (if applicable), disable DOD (if applicable), and remove any restrictions preventing operation of the engine when installed in a different vehicle.

    If the engine has a different camshaft, ANY performance modifications, or has any components that differ from options selected on your tune request the following issues may occur: No start, erratic idle, surging, check engine lights, limp mode, lack of shifting, no throttle response, poor power delivery, and other issues possibly rendering the engine inoperable. Any engine or transmission modifications will REQUIRE a custom tune to ensure proper operation and prevent serious damage. PSI Conversion cannot be held responsible for issues related to operation or performance when the engine/transmission has been modified, or varies from the options selected when the tune was installed.

    • Perfect
      The PCM works flawless with the harness PSI offers. I first ordered the LS harness and realized I had issues with my stock PCM, I then ordered the new PCM from PSI. As long as you are able to correctly answer the questions for the base tune you will receive an unlocked and functional PCM to use with your stand alone LS harness.. I would, and likely will order another harness and PCM from PSI for my next LS swap.

    • PCM
      This is exactly what I needed. I was stuck and couldn’t move forward on my LS Swap without a tuner. The PCM allowed me to start my engine and check for leaks and electrical fans were wired correctly. Perfect with the PSI wiring harness! I would have been lost without PSI.

      Thanks, 
      Will

    • Running again
      After spending way too much time trying to get my junkyard vortec swap running. Never able to get o2 sensors working and random codes,finally purchased a PCM from PSI. Car fired right up and all codes cleared. PCM came with stock tune for my engine/transmission. It’s been in the car for a month now and car runs great. Definitely recommend.

    • Fantastic Product
      I purchased this PCM, along with PSI’s applicable harness, for an LQ4 swap into a 60s truck with a non-electronically controlled transmission, and I could not be happier. The start up tune worked flawlessly, and the truck started up first crank and idles without any issues at all. I would highly recommend this PCM to anyone doing an LS swap. Just be sure to realize that a dyno tune will still be needed for full driving.

    • Vortec Engine PCM With Programming (Green/Blue) P59 242
      Worked perfectly upon installation and continues to do so. I can't rate it's durability as yet since I've only been driving with the PCM for a month or so but I have no reason to expect it will not last.

    • Make your swap easy
      All of the products purchased were of very good quality and workmanship. Everytime we had a question the staff knew the answer immediately and were very knowledgeable. I have recommended PSI since then and my customer had the same results as I did. I will for sure be using PSI again.

      I needed help with my purchase as I was inexperienced with the LS conversions. Could not ask for better support from everyone I dealt with.

    • Scout 800 LS swap
      PSI was great to work with, called them, gave them my specs over the phone. Computer showed up a few days later. Everything plugged into the PSI harness and worked as it should.

    • ECM support
      Before hearing about PSI I purchased a wiring harness from another company and they couldn't or wouldn't support my ecm requirements. PSI gave me the support I needed. I will be using PSI. For any future projects.

    • Fires up the first time, every time!!
      I struggled with buying a PCM from PSI or having mine mailed off and tuned. The price wasn't a factor but in my particular build i needed something i knew was gonna start and run. PSI always delivers on their promise.
