E46 M3

We have been tuning the venerable S54 and E46 M3 platform since 2008. 

At that time, the tuning world was slowly discovering the inherent strength and power producing capability of this engine. Matched with the exceptional E46 chassis and cockpit dynamics, this car has been a favorite of enthusiasts young and old.

We initially began calibrating these engines for road race where we learned about the thermal and RPM limits for consideration. Years later we began calibrating turbocharged S54's pushed the power into the 4 digit ranges. We were able to set many records including the quickest 60-130, 1/4 mile, and half mille E46 M3's, in addition to multiple endurance racing trophies.  

Fast forward to 2018 and we began our Syvecs program to revamp engine controls for the E46 M3 platform. Working with Syvecs gave us the opportunity to level-up to a motorsport-grade ECU and supporting hardware that has never been a plug and play option for this platform. While we know the market for this is limited, our goal has never been a high volume of clientele, but to work with those who care the most about their cars operation and function, along with integrating as many features as possible into the calibration.

We have worked for more than eighteen months sniffing the CANbus system, calibrating sensors in laboratories, integrating steering wheel and sport button controls, traction control, map switching, rolling boost, launch control, and more. Combined with the race-grade firmware that Syvecs already supports and it’s a winning combination.  

This product is finalizing completion and is available for sale now. We will only tune units we sell in an effort to protect our work on the platform and Syvec's investment in our work.
