I'm sure most of you have been at this much longer than I have. I have a quick question..
How accurate are the torque and boost PSI numbers that are logged by VCM Scanner?
I'm not trying in anyway to replace going to the dyno, however, I'd like to understand the accuracy of the numbers that the VCM Scanner produces for our cars. Mine is a 2011 S4 (B8). I would assume that, at best, it is generating calculated, or ECM produced, numbers for all PIDs, and from torque perspective what is expected at the crank. Is there a correction factor I should be using when looking at the raw numbers?
Just curious...
