E85 BRZ Tuning Results!

We spent a few tanks of ethanol testing various combinations/mixtures and using the currently available E70 blend, and achieved more than 20hp gains just about everywhere!

Compared to running on regular gas the car is like night and day, and the performance stays much more consistent as things get warm. While we can integrate ethanol content detectors, this is currently implemented via map switching, where we can set up maps for various blends. The ECU can compensate for in between those settings.
