    About This Brand


    MegaSquirt Plug-N-Play Engine Management
    When your time is money (or you just don’t have time to spare), it’s worth paying a bit extra to make the installation go as smoothly as possible. You don’t want to go through a list of options and specify what you want on the ECU like you were ordering a pizza, and you definitely don’t want to solder one together from a kit. You want something you can just take out of the box and have it work. This might take the form of a universal ECU that’s got all the inputs and outputs it needs to run a wide variety of applications when you wire it up, or it could be a plug and play system that plugs right in place of the existing ECU and is ready for you to start tuning. Unplug your stock ECU, plug in the MSPNP, run a vacuum line to it, and fire your engine up on the first turn of the key if it’s at all similar to stock. If you’re running bigger injectors there’s one setting to change and then you’re ready to fire your engine as well. It really is that easy. The MSPNP is a true plug-n-play ECU that we offer for an ever-increasing line of factory fuel-injected cars. It includes every feature you need to have full control over your fuel and ignition, plus features like electronic boost control, launch control, table switching, adjustable rev limiters, and other things normally not found in a stock ECU or even a hacked/re-tuned OEM ECU. Check out all of the Megasquirt ECU kits available here at LMR.com!
