with the tuner itself, you can tune wot fuel and spark... but it's important to datalog (with wideband) so you can see how the truck runs in open loop... do you have a custom tune on the tool that your downloading onto your pc? generally, when a cmr tuner does a tune for you the custom tune itself sits on the tool. You can then download that tune from the tool to your pc. In general, you don't download any canned tunes.
