Frequently Asked Questions
Global B E99 Flex Fuel - C8/CT5-V & CT4-V Blackwing/Escalade V is a flex fuel kits solution for performance fuel-system applications. Review the fitment and configuration options below to select the correct setup for your vehicle.
We are proud to present the ability for anyone to do flex fuel in the E99 ECM for GM vehicles! The cornerstone of this setup is a modified operating system that allows traditional pinning of the ECM which will stay active as long as the operating system for the ECM is overwritten at a later point in time. Once the modified operating system is flashed (requires the use of a HP Tuners MPVI4 or RTD4), the tune can be edited just like any legacy ECM to activate flex fuel! This means no other inputs have to be taken over and any exhaust valves stay fully functioning like stock.
The base purchase is the modified OS itself which is deployed through the HP Tuners TDN (tune delivery network). Once you upload any file from the target vehicle to our TDN, you'll receive back a file that only supports write entire and is not downloadable. You'll also receive a file that you CAN download that has all the necessary settings turned on without the modified operating system. This allows us to protect our work while making it available to everyone.
As noted, you will need to have a RTD4 or MPVI4 for this to work. Should you need a MPVI4, we can provide you with one. If you also need the credits, we can preload them to your account. You will need to provide the VIN for the vehicle because we will use it to validate your purchase relative to the uploaded file.
