i have a tow tune that i use all the time and it always throws a p0101. I've check it with my other tunes and everything seems to be in order. Is there anything else that I can check? ask away for any info that you made need to help. Thx very much in advance!

If tune seems fine you can disable the DTC code for that in that tune. Otherwise have to adjust the MAF table. I would monitor and log the MAF PIDs from one tune that does not do this and then the tow tune to see its high and lows. Have some one watch the log and mark when the code throws.

Makes since, I can't log right now b/c of bad weather/tornados in the area. in the search i pulled up p0101 and check the c0905/c0906 and they are the same as the race tune. -20/100. How do i disable(maf) or is this bad? The tune seems fine when running but when the code is thrown i do get worse gas milage. Will trurning it off effect anything? thx for your help

Go into the Engine Diagnostics > DTC Enables and search for P0101. Should be first page of them. Then change to X Not reported No Mil. Save tune and upload. As to bad I don't know. I do this to some EGR codes since I have the blocker plate and works well for that. Seems even if you disable the EGR you may still get random codes.

I disabled the code because one of my tunes also would throw it. It seems to happen to me when I run a throttle base table that is altered quite a bit. I disabled the code in both DTC tables and then I also increased the eror allowed just to be safe.
