E46 M3 Cluster Mod for Non-M

Now offering E46 cluster modification service.

Have a 4-door and need the LED’s added to indicate open doors?
Want the Redline LED’s adjusted to show the correct redline for an engine other than the S54?
Prefer an accurate speedometer? The M3 is configured to be 9% fast versus the non-M at 6% fast. The M3 cluster can be coded to be any percent desired.
Prefer an accurate temperature gauge? The S54 naturally operates at a lower temperature than the M54, resulting in the gauge reading past half when installed in a non-M car. The M3 cluster can be coded to behave more like the stock non-M cluster, or specific temperature limits can be supplied by the customer for more accurate display of temperatures.

This service requires a core cluster to be sent in, so please contact for details prior to purchase.

NOTE: This is the cluster mod portion of the task only. For full “M3” functionality you will also need to reprogram the engine DME.
I offer engine DME reprogramming for MS43 cars (2001-2003 rwd, all xi) only.

For MS42 cars (1999-2000 E46) it is possible but not a service I can provide. For MS45 cars (9/2003+ except Xi) it is only possible with an aftermarket module.
