BMW Z4M (2006-2008) MSS70 ECU Tune - Supercharged Alpha-N

See our full write-up for more details and other tuning options!

Supercharged Alpha-N: This tuning service includes all the features of our naturally aspirated alpha-n tune, enhanced to support forced induction. We can tune supercharger kits from any of the three major manufacturers (ESS, VF Engineering, and G-Power), as well as take each setup to the next level. Alternative fuels, larger injectors, and high boost are our specialty! Our official Severn Tuning race car runs this supercharged alpha-n ECU tune with full E85.

Additional Tunes: Three additional tunes can be purchased for $500. Examples include summer/winter, high/low altitude, pump/race gas, E85, OBD2 monitoring on/off.

EWS Delete: We are one of the few that offer EWS deletes for MSS70. Commonplace on race cars, an EWS delete allows for "hot swapping" ECUs. Customers can have multiple ECUs with different configurations and switch between the ECUs at any time. Please note that EACH ECU requires an EWS delete modification at $300 per ECU.

FIC Fuel Injectors: Severn Tuning recommendations are as follows.

525cc - Naturally aspirated applications on pump gas, flex fuel, or full E85; forced induction engines up to 400 whp on E85, or 520 whp on pump gas
650cc - Forced induction engines up to 500 whp on E85, or 650 whp on pump gas
