Is it the same truck you have successfully done a DSP for already though?

Have not successfully done dsp to my truck yet. THis is my first time to build one. I have loaded others that have been bought for other trucks.

Got the file, thanks. It is already a DSP5 OS which is why it cannot be upgraded again

I dont want to upgrade it, look at the upgrade tab and see what it says. When I load the dsp tune it doesnt work. It stays on the same tune.

So let me ask you about the switch. The pid said 4.98 volts and another said non dsp. How do I know if it working?

any thoughts?

The file you sent me is already a DSP5 OS, so it has been upgraded already by either yourself or someone else. It is not a case of wanting to upgrade it has already been done, and cannot be done again. That is what that tab and explanation are telling you. For instance an LS1 COS is not able to be upgraded by using the Upgrade OS tab in the Tune Tool.
To get the DSP to work in your vehicle you need to perform a full-flash, to upgrade the base operating system and calibration areas.
You log the GM.E35DSP5_DMA PID (which it seems you already are. You know it's working if you see that change when you make a selection on the DSP5 switch. The 5 positions are made up of Non-DSP (standard calibration tables) and DSP#1 - DSP#4 table overrides.

so if I have the scan tool going and I change tunes should the volts cahnge too? from say 4.98 then down from there?\Thx for your continued help also. And I have asked this in so many different ways on all the forums.

Yeah, the switches have a different resistance on each switch position that effects the voltage seen by the ECM on the switched input. That is how the ECM knows which DSP (or Non-DSP) calibration to reference.

I'm having a similar problem, I am unable to build my tunes 1-4. Not sure really how to do it. I have the base tune built but I do not know where to make the changes for 1-4. Also, how do I make these changes translate to the Edge evolution CTS?
