So did some logging yesterday night of my 3rd and 4th gear from approx 2000rpm, and the results are in.
I logged channel 11, 03 and 10
Certain places it sort of spikes downwards, but please could you guys explain to me the results.
The Actual MAF reading is higher compared to the specified, however this could be due to the EGR bypass I have in place.
