Coyote torque PID for VCT tuning

[rhinogt]

I have been using Engine Brake Torque to create a math for Horsepower to have a semi dyno chart when doing WOT pulls. This has been to aid in VCT tuning and cut down on dyno time.

The question is: Is Brake Torque be the best PID to do this with? I has appeared to be consistent but I just wanted to ping those much more knowledgeable on their opinions.

I do the same, its about the best you're going to get without a dyno. It doesnt take into account all losses (from my own experience playing with it on the street and then going to a dyno and comparing) but it is good enough for rough estimates.

How are you setting this up if you don’t mind me asking

Log Engine Brake Torque, then set up a user defined math for horsepower. (Torque PID * RPM) / 5252. The add the torque PID and the horsepower to your graphs.
