This is a 2009.5 hardware ECM for G8s that is intended to be a plug and play swap (no wiring changes) for 2008-2009 G8s. It allows the use of more advanced tables and further functionality. Expanded IFR and MAF limits, editable axis labels, and more!
Please provide your VIN upon ordering so it can be properly programmed and specify auto or manual. You will need new licensing for these via HP Tuners or EFI Live. Please contact firstname.lastname@example.org with any questions.
