Disable the MAF by causing a MAF DTC to immediately show up...
this can be done in any one of these ways:
- unplug MAF if you have 3-wire connector (i.e. IAT is on separate connector).
- edit C2901-3 to force MAF to fail.
You may have to edit C6001 to cause P0101-3 to trigger on 1-Trip.
If you don't have a wideband then you will only be able to correct VE for Closed Loop, i.e. low/light throttle only.
