Previous Owner MAF Delete?

[Ubaderb]

I finally got around to messing with the Ecuworx software and noticed that the "Enable Alpha N/MAF Delete" is selected and grayed out. Anyone have any tips on how to remove this? I have emailed Martyn but I can tell he is a very busy man. Surely this can't be good to run the car off this right?

Does your car have a MAF installed?

Usually when it is grayed out, it's because a tuner has modified those parameters and Martyn's tool is unable to modify or revert them.

Yes. I even double checked today that it was plugged in and not a blank or anything like that.

So someone like Hassan at HTE could tune over that? Just a little worried on how bad driving without it is.

Yes, he should be able to do that. If anything, the factory software can be written to the ECU and it will put it back to factory settings.

Use OBD-Fusion and make a log with data of pre-cat sensors and all the fuel trim (short and long). This will tell the status of the mixture.

If the MAF is still there, it might be used for the Alpha-N tune as a IAT sensor.
