DSP5 question

[Tarkstoys]

Have followed the instructions and still something is wrong. Getting four volts from switch per scan tool pid.
THis is what the tune says in efi upgrade OS-
The currently loaded *.tun/*.bin file operating system does not support custom operating system upgrades using this option
What am I doing wrong?

What software version are you using? You could send your file to me (support@efilive.com) and I could see if it works for me.

[Tarkstoys]

V7.5.6 build133 and suggestions

I also try now to make another dsp5 tune and it says this upgrade cannot be undone. on all tunes?

[Tordne]

The DSP upgrade cannot be undone. You need to save your stock or current file first and then save the DSP as a new one.

I have all my files saved to other computers. 1st dsp tune was base a race tune. Next dsp tune I tried to make it sad this?I can't even get the first one to work?

[Tordne]

You've lost me now! Does the software let you upgrade your calibration to a DSP5 or not? You only do the DSP5 upgrade once and then change the 5 tunes. What actually happens when you do the DSP5 upgrade is that there are significant changes applied internally to the operating system (which is why it can't be undone). You don't need to apply those changes repeatedly just to change the #1 - #4 positions.

Sorry, yes I have one dsp tune that is completely done. But in upgrade OS it says what is stated in post 1. I've read the direction a few times and seems easy. Just not working for me.

Are they both the same operating system, or are they for different vehicles? Can you send the problem file to me (support@efilive.com)?
