Overview

HP Tuners offers a send-in upgrade service for the GM Global B E99 ECM (found in 2020+ GM vehicles) to enable diagnostics and tuning in VCM Suite (BETA) software. Users must ship their original E99 ECM to HP Tuners. Once upgraded, full access to calibrate, log, and scan is available via the OBDII port. No IMMO Relearn, Crank Relearn, or "Replace ECM" function is needed if the ECM returns to the same vehicle. Tuning requires an MPVI3 or MPVI4 interface and the latest VCM Suite (BETA). MPVI2+ and older devices are not compatible. Service takes up to 7 business days, excluding shipping.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
