04.5 LLY wont accept DSP5 tunes or data log

[TRUBBS]

trying to get my truck set up for dsp5 tunes
ive gone through all the steps correctly for making the tunes in dsp5 format
i know for a fact the wires are pinned correctly, even have tried holding the black wire directly to ground and stil nothing
everything is up to date in both v8 and v7.5

when i full flash the new dsp5 tunes in and go to switch tunes, it just stays in the stock tune and wont change
when i try to data log the pids for dsp switch it says something to the extent of "pid cant stream, must be in dynamic stream mode" and ive made sure it was in that mode, and tried it in every mode i can with no luck

Thats pretty much a short and sweet version of what ive been fighting with
anyone ever had this problem?
any ideas how to fix it so it works right?

Is the tune set to serial or hardwired for the switch ?

Hardwire

How many PIDs do you have selected? Try unselecting all PIDs and only select the DSP PIDs and see what happens. I have had that message pop up before when I had a PID that was not supported by that controller.

I only have the 1 dsp Pid selected

i just had one where the voltage was not set when i upgraded to dsp5 could see voltage change at switch but not chaning tunes. its worth a look

Ill try anything at this point.
How to check that tho?
I'm still learning all the fun EFI stuff lol

if you log dsp5 voltage lb7-lly you should see voltage change on the scanner and its the first table under youre dsp5 tunes ( sorry at work not at tuning computer)

i cant log to see it tho, thats half the problem lol

What voltages does it say each dsp tune is when viewing the calibration in tune tool?
