E46 M3 ‘CSL’ SMG Software Flash + CSL Rev Matching Remote Coding

This service is to install the fabled ‘255’ CSL software on your SMG2 TCU (transmission control unit) and to reprogram your DME with the CSL shifting and blip parameters (otherwise known as CSL Rev matching + inertia fix).

When the 2 modifications are performed, you’ll get more responsive, agressive shifting whilst smoothing out downshifts with the legendary CSL downshift rev matching.

If required we can also offer the following as part of the service free of charge:

– Top speed limit removal
– Disable SAP / Cat heating sequence
– Recalibrate warm up lights
– Enable sport mode memory
– Disable cat efficiency DTCs after decat installations

This service is a ‘must have’ for your SMG equipped E46 M3.

A ECUWorx Pro Cable – Dual K-Line Flashing Cable is required for this service.
