Gentlemen:

One last issue. What is seen on the TunerPro screen and what is read off the balancer with a timing light are different numbers. Is there supposed to be any type of correlation between the two or is the TunerPro derived timing an offset value to be added to the balancer read number? Balancer timing on run-in stand (no load) is varying between 0-10 degrees advanced at or off idle. Just wished had a bench signal simulator and output data capture that would capture all the data side by side to see just what the interrelationships, between inputs and outputs, built into the binary file. Please advise. Thanks.
