Success, finally! I got the brain back today, for the third time. The TPS error has been solved! I have only run it a few times, at 20% (35HP gain) in linear mode, but all is well. Now for some testing and adding more % in increments of 5. Once I bed down the Linear mode, I'll work on Drag and Timed. The kit will soon be available - I'll post part numbers and required software revisions when avilable.........
A huge thanks to Greg (and Joe) at Python Injection!
