ETC Angle Error Doesn't Make Sense

[Sebastian8501]

hello anyway someone with experience on the 65mm TB can lend a hand I have a gen 3 and the tables are kicking my ass. Mods are CJ, PMAS, 65MM TB and JMS signal converter. Car is a gen 3

Doing some tuning on my new FRPP Twin 65mm TB and trying to get it idling better.

I thought that I had a grasp on the ETC Angle Error meaning, but am seeing odd values:


Attachment 81010


For the idle condition shown, both my Effective Area and Predicted angle tables point to something around a 1.3* ETC angle, with the current angle being 1.2*. So why then, is my ETC Angle Error at 0.83*?
