Upgrade Process:

Our E99 ECM upgrade service involves sending in your original ECM to ZackTuned’s headquarters. Once upgraded, your ECM will be fully compatible with ZackTuned’s tuning software, providing you with comprehensive tuning access. The process is simple: remove your E99 ECM, ship it to us, and upon receiving your upgraded ECM, you can calibrate, log, and scan through the OBDII port, enabling you to fine-tune your vehicle’s performance.

Why Upgrade with ZackTuned?

• Full Tuning Access: Gain complete control over your vehicle's performance with unrestricted access to calibrate engine parameters, ensuring your vehicle performs at its best.
• No Additional Steps Required: After the ECM is upgraded, there’s no need for an IMMO Relearn, Crank Relearn, or to perform the “Replace ECM” function in VCM Scanner on the stock ECM, making the process straightforward and hassle-free.
• Supported TCM Upgrade: We also support the GM Global B T93 TCM found in select vehicles equipped with the E99 ECM and a 10-speed automatic transmission. Explore our GM T93 TCM Service (Global B) for more details.
