AJ16 Plug & Play ECU/Loom

Swallow Racing in conjunction with our partners at Performance Vehicle Engineering have created the first plug and play AJ16 Loom & ECU Packages.
A complete solution for running the AJ16 family of engines in pretty much anything! This package is shipped complete with ECU, and plug-in loom, as pictured. All you need to do, is supply an ignition feed, a 12v constant feed, and add in a fuel pump & fuel pump relay. This runs the later 2-pin coil packs. For other options please contact: We can build these at various lengths, for ECU locations at various different places in the vehicle. Again, this can be discussed with Swallows Racing. ECU is shipped with a ‘base map’, suitable for running a standard engine, with standard injectors. Our package is based around the MaxxECU Street. This ECU has full control of this engine like it’s never had before! Full closed loop wide-band control. Supplied with genuine Bosch LSU4.2 sensor. Fully sequential fuelling, and ignition.
  • CAN bus
  • USB communication for tuning with MTune

    Would this system be suitable for road use, rather than racing?
    Does it require alternative inlet manifold, injectors, fuel rail etc?
    And how much does it cost?

    Alloy blocked, straight 6 with a supercharger, 24valves, and built solid. Tom, from Swallows racing, and myself again sat down before COVID of course, and discussed a plug and play loom and ECU package.
