2016 Camaro E92 MAF Scale question.

[PRAY]

I was building a base tune file for my Camaro yesterday when I noticed that the MAF table goes to 8500hz and then skips to 15000. There is no data shown or scale shown in between. The MAF Freq 2 table is complete so I though it was a glitch or something but apparently it is the same with HPT. Is there a way to show this data or re-plot the scale to show it. I dynoed the car stock today and it hit 8400hz. I am going to need the rest of that table to do any mods to this thing. I am assuming that if there isn't a way then I will just add what ever percent to the 15000 slot that I did to the 8500 slot and hope the computer adjusts the curve? I know I can just hit the PE table or the VVE tables I guess but I would like full control over all of the fueling tables.

May I see your tune file...?

Yes Sir,

Thanks Joe

I haven't seen people mention this as an issue yet but I know there are a bunch of forced induction products going on these cars so there has to be a way around it. Most of my H/C cars see into the 10K hz range. My stroker motors make it into the 11K range.

Joe, something else I noticed is missing from that I had access to in the C7 files is B2524 BTM Torque Limits. It doesn't exist in the Camaro file under the Torque Control tab. IIRC, that table has something to do with how fast the throttle blade opens going to WOT.

Yep, B1099 does not look right, I'll alert Paul.

Thank you Sir. If anything can be done about the BTM table as well that would be great. That is all I have noticed so far as dufferences.

Is there a way for me to make a table with the missing areas in the mean time?

Yeah I agree I wouldn't expect the axis to increase at the rate it is, I'll have it checked out.

We double checked the definition of the MAF tables and they are correct, I don't know what GM was thinking with these but it is like they wanted high resolution under 8550 Hz and then beyond that there is a VERY steep linear blend to 15,000 Hz. It could also be computer model generated numbers which is why they look uneven to what we are normally used to seeing.

And GM provided MAF #2 table B1100 which looks ok (axis range does not jump)...

how do you go about running this table instead...?

I'm wondering if MAF #2 has an ECM pinout...
