I've been lagging on the project for a long time, but the issue was that the long-term results were not correlated with the initial test data. That, and the fact that I don't use my car that much. Each test requires at least 25L of fuel. Moreso, 25L (just above a quarter of my tank) is not enough to let the car calibrate its closed loop. Usually it requires a full tank and lots of driving, about 800km each test. It's hard to do a consistent driving cycle for that distance. My aggregated data shows that the circuit DECREASES mileage now, perhaps with about 10%. And that is with settings almost identical to the ones used by RaceChip, a bit more aggressive. In other words, with a REPORTED LOWER rail pressure and ACTUAL HIGHER rail pressure the CONSUMPTION INCREASES by ~10%. I suspect that most of the people that report decreased consumption actually use on-board-computer data and do not perform precise measurements. So I've changed my strategy now, The reported (fak...
