As for the voltage, I am wondering if the voltage is varying. All the resistors do is vary the voltage, but if I am inputting 14 volts and run it through the resistance chain, I might get 10 volts versus if I run 12 volts through and get 8 volts. I am wondering how touchy the trans might be on needing a very specific voltage for the TUTD to work.

Since you have a 6l, when I shift through the gears, it works like this:

Park
Reverse
Neutral
D6 (Automatic shifting to 6th gear)
D4 (Auto shifting to 4th gear)
D1 (Stays in 1st)
D2 (Auto shift 1-2)

Is this correct? This is the dumbest thing I have ever used. If you use D2, you have to go back into D1 to get to D6.

Thanks, Ron
I never shifted past D1

with the current tune (ish) that it has, When i come to a stop light and there is a need to at about 20 mph, i will shift to D4 it downshifts and rpms and exhaust notes sing a little, then to D1 and its like rev matching... silly but sounds cool... ill have to get a video of it ... probably make more sense

As far as HPtuners displaying it. I have a VCM scanner file I cobbled up, that

87chevy.com/tapshift2023.Channels.zip

its a zip folder with the .xml file that hp tuner uses for channels that I added the transmsision PIDs to it

my folder is in located:

C:\Users\xxxx computer name xxxx\Documents\HP Tuners\VCM Scanner\Channel Configs

You dont have to paste it there, but when you go to VCM scanner and open a config file, you can just look for it wherever you downloads go.

See if it displays correctly? it should read the gear displayed, and then if in sport mode/tap up tap down. I will connect the laptop to the X5 swap tomorrow and take a video of it displaying the inputs.

I think I sold you a Gen5 connector kit from ebay... your screen name sounds familiar.
