A video I created for my Ford EcoBoost (Focus ST, Focus RS, Fiesta ST, EcoBoost Mustang) remote tune customers demonstrating how to perform the various types of datalogs required for Remote Tuning (E-Tuning) using a V3 COBB AccessPort
The various forms of datalogs demonstrated are:
1) Idle Datalog - This allows me to analyze how the engine is running at idle especially in relation to RPM, AFR, and Fuel Pressure
2) 2nd or 3rd Gear Acceleration Datalog - This allows me to calibrate for the appropriate fuel delivery by analyzing fuel trim data in relation to the RPM and Engine Load in a steady & controlled manner.
3) 4th Gear WOT Datalog - This allows me to optimize the engine for maximum power potential by dialing in boost, fuel, and ignition timing and analyzing how the engine sweeps through 4th gear at Wide Open Throttle (WOT). 4th Gear will provide the best load & boosting characteristics which is why this datalog must be done in 4th. Doing this log in other gears for tuning purposes can result in potential engine failure as the tune will not have been properly calibrated for the best loading characteristics that the engine sees.
