Just curious why you would want to data log the 4 th gear lockup--All lockups are commanded by 2 things throttle position [B]and MPH----Look at your tune to see what is the commanded lock up in 5th say at 20% tps---and see if it indeeds shifts there--Lock up apply speeds are easy to diagnose---The onlt]y times the commaned lock-up speed won't match the actual is if the 3-4 shift speed is to close to the 4th gear lock up--
Either they will happen both simostainiously or the 4th lockup will be delayed by 5-8 MPH after the 3-4 shift
