I'm just curious about other peoples opinions here.
I have a 2009 VE SS Sedan Auto, and the wideband tuning has been for ve on a dyno, and the maf as well. Now I've tried various tunes etc, the problem I have is if I switch the car to mafless mode the auto's shift points go a little haywire, the on and off throttle is choppy and the timing goes nuts...... it can drop 20-30 degree's in an instant and also gain the same amount.
The car runs fine with the maf, but mafless it does weird things. Now some people do spark smoothing, remove torque management and all the rest of it to get the mafless to run correctly, but it will never even doing that drive as well as a maf setup......
I read on the forums on here about the torque co-efficents being out ...... would that also explain the odd timing drops etc?
It's like the car WANTS to know MAF readings..... to control torque and timing and all the rest and by removing it, it just craps out......
Really to convert it to mafless we really should be able to just turn off the maf without needing to change other things because if the fuel and airflows etc are right, it should be fine, you shouldn't have to remove all the torque management and all the rest.
