Coding for engine swaps is our specialty. All check engine lights are operational and the DME is coded for your specific setup. Please use the menu below to select your options.

CSL SMG Shifting Parameters – the majority of the shifting logic is in the DME. Makes a HUGE difference for rev matching sportier shifting. Recommended with CSL TCU flash

SAP Delete – Removes coding for SAP and trouble codes
Post Cat Delete – Removes rear oxygen sensors, great for aftermarket cat-less headers
