This Race Fuel Tune is an add-on service and must be purchased in conjunction with a Dyno Tuning session or Virtual Tuning session. It is not offered as a standalone tune.

This calibration is designed for riders looking to extract maximum performance using E85 or MR12 race fuel. The tune is built around the higher octane and oxygenated properties of race fuels to safely increase power, improve throttle response, and optimize high-RPM operation.

What’s Included:

• Fuel map calibration optimized specifically for E85 or MR12

• Ignition timing adjustments for race fuel

• Throttle and torque optimization

• AFR optimization under high load and wide-open throttle

• Review of engine safety parameters

• Data-driven refinement using dyno data or logged runs

Requirements:

• Must be added to a Dyno Tune or Virtual Tune

• Dedicated fuel system setup for E85 or MR12

• Proper injectors and fuel pump (as required)

• Wideband AFR sensor strongly recommended

• Customer must supply race fuel

Important Notes:

• Race / off-road / closed-course use only

• Not intended for pump gas or mixed fuels

• Switching back to pump gas requires a separate tune

• Not recommended for daily street use unless discussed in advance

This add-on is for riders who are serious about performance and running the correct supporting hardware and fuel to match.
