I have a 1972 Chevy Nova that has the LT4 with 8L90E connect and cruise. I am having a very hard time getting the tranny tuned to shift correctly and what doesnt help is the channels that are listed on the left side (in text) do not match the gauge values to the right and I cannot figure out why. Have a look at the data log (attached).
For example on the gauges to the right it may say I am in 8th gear doing 21 mph at 1199 rpm. But on the left it says I am doing 58 mph in 8th gear. Do I possibly have a wrong channel selected?
Please help as I have been fighting this for way too long...
