    Technical Ignition advance on E85

    How much should I run? Gonna take a stab at tuning the car myself. Most logs I've reviewed from others with my setup (Doc Race / gen2 precision 6266 on full E85) have timing around 10* up top, but that's on a stock motor. I have a built bottom end and JE pistons with beefy ringlands and rings...
