The PNPECU PnP adapter kit for the M52tu MS42 allows you to gain full control over the engine while allowing easy fitment into your car, be it the original car or after an engine swap. All OEM functionality is maintained where possible.
Some functionality may not be available with your supplied ECU so contact PNPECU to discuss
The stock cam sensor is not supported and should be replaced with a M54 camsensor part number 12147539165
Please discuss with PNPECU if you wish to buy the kit as there will be several limitations but might still work for your particular situation.
The wiring adapter plugs straight into the OEM engine loom and then onwards to your ECU
