Been here a long time ago with a different animal (97 Formula). Coming back again for my 98 LQ4 H/C/I full bolt on T/A. I have been lurking for a bit trying to figure out a an issue with my TCI 3500 converter and not being able to get my 1/2 shift without letting out of it and hitting part throttle for the shift. Old converter had a big time failure and was leaving my 414hp/411tq car with a 2.68 60'. Knocked it down to 1.68 regularly however my trap is a good 15-20mph lower than it should be in the 1/8th. Looking to invoke the wrath of the HPTuner gods to maybe help me out and pass my knowledge along! Dropped my MPH and RPM shift points low but still not getting the 1/2 shift, and no clue about 3/4. VCM Scanner wasn't picking up my TPS however voltage testing it shows good at .66 no input and 4.53 full bump. Any inputs are welcome, and I look forward to passing anything I know down the line as well!
