I'm using V4, tuning a '93 vette (LT1) and have a question. The TP website shows a DA3 xdf and a DA2 ads, but TP indicates a mismatch. Is this a problem and if so, what's the net affect? I looked at the DA2 xdf and it's substantially limited compared to the DA3 so I'd prefer not to use it.
Its not a big deal, just tells you if you change files.
You can edit the XDF header info to point to your ADX file and the message will only come back if you change the file names.
There is also a check box in the Preferences (DAQ tab) so you can disable the warning message.
