Speed Density tuning 2013 Cruze help appreciated.

[Dr2Smoke]

Hey everyone, hope y'all are having a great day. I'm speed density tuning the VVE table on my 2013 Cruze e78 ECM and have a problem.

When I fail the MAF and set the MIL to report on 1st error, my coolant won't get any hotter than about 150?F. This happens even if I have ses checked but with no MIL option.

I have the MAF failed in the tune every way I can think of.

Any advice is appreciated.

I just go to "engine diagnostics", Airflow and set MAF fail high to 100, and MAF Fail Low to 110. Then have it fail on fist error. PS, I'm not an expert.
