I have a Bosch MAF (Mass Air Flow Sensor) that seems to work as it should.. So the MAF is switched off on my unit..
The question is, what range of tuner settings actually work under those conditions?
I tried setting 3 for a while, then went to setting 6, but it doesn't seem to be any different?
As yet, I haven't tried either setting 9 or 10 , in fact 6 is as high as I have been so far..
Things I do know.. from 50 mph to 70 mph takes a fraction over 6 secs. Heavy acceleration from a standing start causes front wheel spin and not much else! on a damp road the front wheels will spin in 2nd or 3rd if you "floor" it..
MPG is pretty constant at an ave of 32 mixed local driving, and ave of 42 mpg on longer M/way runs which include pretty constant speeds around the low 80.s ..
I know 70 is the speed limit, but as we all know, get out on an M/way, and weather and traffic permitting, most cars are doing around the 80 85 mph mark ..
I am not complaining here, I think my 75 performs well for a heavy saloon 2 litre CDTi auto. I'm just after more information...
