Were the Pbox times faster or slower (or varying) compared to ECUx times?
When plotting Vagcom generated acceleration curves (based on delta rpm/sec), I find that the data are OK up to approx 5000rpm, but start fluctuating after that, probably due to the decreased sample rate at high rpm, so I agree that only Pbox/Vbox times should be used for the official list.
I use an accelerometer based datalogger (made by the guys that make the Mustang dynos). It spits out power/torque numbers similar to a correctly calibrated Mustang dyno, and the time to speed is dead on accurate (spot on with track timing, magazine tests, etc), but since my times are not Pbox/Vbox based, they should not be added to the list. I will just mention times that I measure in posts, for you guys to use as a reference.
