New Step by Step Map For custom ECU reflash

Nonetheless, The mix of the/File ratio and ignition timing that minimizes injector duty cycle and EGTs (for just a offered combustion temperature) will show which the minimum amount of surplus gasoline was additional Which combustion was initiated at the correct timing to ensure that the facility stroke used up the maximum amount of Electrical power while in the cylinder (causing significantly less Electrical power/temperature in the exhaust gas). A bit richening the A/F ratio a 50 %-position richer than the Leanest for Best Torque (LBT) is a good observe to supply a safety margin.

The main bootloader is employed for software reprogramming plus the secondary bootloader is useful for bootloader reprogramming.
