Want to run E85? We enable flex fuel functionality in your GM ECM/PCM so it reads ethanol content and adjusts fueling and timing accordingly. This lets you safely run E85, gasoline, or any blend in between - ideal for making more power on pump ethanol without swapping tunes.
What’s involved: enabling the flex fuel tables and ethanol composition sensor support in your calibration. A flex fuel (ethanol content) sensor and compatible fuel system may be required on your vehicle - ask us if you’re not sure what your setup needs.
Mail-in service: ship us your module with your VIN and mod list. See our How to Ship Your Module page for packing and address details. Typical turnaround is 1-2 business days after we receive your module.
For the best results on E85 we recommend pairing this with a custom tune - contact us and we’ll quote the flex enable and tune together.
