Yes, I got that. I did some testing last weekend and setting "DTC Type" to "X: Not reported" is not very helpful. there are 2 possible results from doing this.
- If the MAF is still plugged in correctly and functioning, it will still be used for air flow measurements as you have just told the ECM to ignore any MAF failures. So it will continue to use the signal coming from the MAF, even if the test settings say it should have failed.
- If the MAF has been disconnected, the car will start and then stall as it will get no fuel. As the PCM has been told to ignore MAF failures and the MAF is disconnected, it will read the air flow as the minimum MAF setting ( in my case 0.55 gm/S ). Given the very small airflow being used, the PCM will simply not inject any fuel and the engine will stall.
So the idea would be to set the following:
If you are planing on going back to using the MAF, the changes should be...
If you are going to remain MAF-less...
DTC MIL - P0101 = No MIL
DTC MIL - P0102 = No MIL
DTC MIL - P0103 = No MIL
and optionally
DTC Type - P0101 = C: Non Emissions
DTC Type - P0102 = C: Non Emissions
DTC Type - P0103 = C: Non Emissions
All these will need to be returned to stock when the MAF is returned to service.
DTC Type - P0101 = C: Non Emissions
DTC Type - P0102 = C: Non Emissions
DTC Type - P0103 = C: Non Emissions
DTC MIL - P0101 = No MIL
DTC MIL - P0102 = No MIL
DTC MIL - P0103 = No MIL
Yes thats how mine are set for mafless.Originally Posted by swingtan
I have made a small update to the guide to take into account the MAF test settings as mentioned in Oztracks post. Nothing major, I just wanted to make sure that the guide was in line with current best practice....

Guys. Will the Efilive VVE tutorial and Swingtans VVE set up still be ok for a 2015 Gen F Maloo (R8 SV pack 340kW. T43 6L80E).
Thinking of smallish cam, intake and CAI with 1 7/8" LT headers and 3" duals.
Thanks.
