Recently started using Tunerpro on a 1995 K1500 5.7L with 4L60E transmission. So far it seems like an incredibly useful tool for datalogging. I have used it for a week, so I'm still learning, but it is similar to other automotive diagnostic tools that I've used. Really excited to see what is possible with this tool!
I am using the $0D adx file (http://tunerpro.net/download/datastream ... D_v250.adx)
I am trying to troubleshoot some torque converter behavior.
When TCC lockup occurs in 3rd or 4th, at vehicle speeds in the 35-50 MPH range, it feels like the torque convert is kicking in and out - RPMs drop a few hundred, then jump back up every second or so. If I tap the brakes, TCC lockup disengages, and RPMs stay at the higher level.
Watching the following variables is interesting:
TCC is being forced off - value is always "False"
TCC Enable Solenoid - always valid except when TCC applied changes state, then one instance of "invalid" when TCC Applied changes from TRUE to FALSE
TCC in Release Mode due to slipping - One instance of True just after "TCC in lock-adjust mode" changes from TRUE to FALSE, otherwise always FALSE
TCC in lock-adjust mode - Appears to be TRUE shortly after "TCC applied" changes from FALSE to TRUE
TCC applied - TRUE when in 3rd or 4th gear and TCC lockup is expected.
Negative Slip recently prevents TCC apply - Always FALSE
I cannot find any description of what "TCC in lock-adjust mode" means - a google search finds nothing, and I've perused a few forums, but can't seem to find a better description of what this means.
More generally, how would one find the details on the adx file variables, and what they particularly indicate?
Looking for more info on variable names/data
