Upgrade Process:

This one-time upgrade service is vital to activate tuning capabilities in your E66 ECM. To start, you must remove your original E66 ECM from your vehicle and send it to ZackTuned’s headquarters for professional servicing. Once upgraded, your E66 ECM will be fully compatible with ZackTuned software, enabling you to calibrate, log, and scan via the OBDII port for optimal vehicle tuning.

No Additional Steps Required:

After your E66 ECM is upgraded, there’s no need for an IMMO Relearn, Crank Relearn, or the “Replace ECM” function in VCM Scanner on your stock ECM. This streamlined process minimizes downtime and ensures your GM vehicle is back on the road with enhanced performance as quickly as possible.
