Load with failed MAF question

[csracing]

As I understand it, the values in the "load with failed MAF" table are Engine Load vs TPS vs RPM.

Assuming that's true, I'm confused. At idle, my tps is at 15% and at WOT it's at 76% per my logs. If I look at corresponding data in my load with failed maf table, I have a value of .63 at idle rpm and 18% TPS. My measured air load at idle is about 20%, not 63%.

Am I looking at this wrong?

I added "relative throttle position" to my log, which shows realistic numbers at idle. What PID should I be using? 2007 Mustang GT.

I'll continue using "relative TPS" then.

Thanks
