GM Gen 4 HP Tuners VCM Scanner Package

Organize GM Gen IV V8 logging and airflow-model review in HP Tuners VCM Scanner. Delivered as one ZIP with matching Analog and Serial folders and a five-page setup and verification guide. Included files: - Analog: 2 channel configurations, 2 layouts and 4 math definitions. - Serial: 2 channel configurations, 2 layouts and 5 math definitions. - General and GMVE channel configurations, paired with Master and GMVE layouts. - Analog math: Lambda Error, GMVE CL, GMVE OL 1WB and Estimated Horsepower. - Serial math: AEM Serial Lambda, AEM Serial Lambda Error, GMVE CL, GMVE OL Serial and Estimated Horsepower. Choose the AEM 30-0300 connection that matches your hardware: MPVI2 Pro Link Analog Input 1 or the gauge's RS-232 output to the Windows PC. Keep the channels, layouts and math from the same folder. Setup is required. Back up your existing configuration, install the calculations in free User Math slots, and assign the matching calculations to entries labeled Bind. The guide covers measured and commanded lambda, closed-loop and enriched sample selection, units and graph filters. Horsepower is an estimate calculated from ECU-reported torque. Release: v1.2 RC2, dated November 9, 2026. Offline replay confirmed recorded AEM lambda and enriched GMVE graph output; trim and horsepower arithmetic was spot-checked. The serial path was checked offline. Complete a clean installation, live gauge comparison and fresh-log checks on your controller and hardware before relying on the results. These are scanner configuration and reference files, not a vehicle tune. HP Tuners software, interface hardware, licensing, wideband hardware and connection cables/adapters are not included.

Intended for GM Gen IV four-stroke V8 applications using HP Tuners VCM Scanner on a supported Windows PC. Check support for your specific controller, operating system, Scanner version and required inputs. Offline replay used a 2012 GMC Sierra 1500 5.3 L recording; this does not establish compatibility with every Gen IV application. Wideband functions are configured for one AEM 30-0300. The Analog folder targets MPVI2 Pro Link Analog Input 1 with the supplied AEM transform. A different input, wideband or transform requires rechecking all measured-lambda references. The Serial folder requires a compatible USB-to-RS-232 adapter and the AEM - AFR serial channel, with the gauge in AFR display mode. The HP Tuners interface remains connected to the vehicle. GMVE calculations require usable MAF, RPM, MAP, volumetric-efficiency and manifold-air-temperature inputs, plus fuel trims or measured and commanded lambda as applicable. Confirm units, operating mode and graph axes against your target calibration. Opening a channel template cannot add missing data to an existing log. Use a controlled environment and qualified supervision for loaded validation.
