Wondering if they have a exchange program. I purchased a tuner from them and did 2 pulls with it. Come to find out I didn't purchase the pro version to measure afr. I've sent 2 emails in the last 2 days but haven't heard back. Anyone know of anything like this.

They do have an upgrade option.

How much would it cost to upgrade from the Standard MPVI to the Pro MPVI if I decided to upgrade later?

Once you log in you then click the order upgrades page for more information. This page will include instructions for all applicable upgrades to your account.

As mentioned there's the upgrade option, or selling what you have at a hundred dollar loss or so, and just picking up the pro version once it sells...

You also don't need the pro version to log AFR - you can use the AC input.

How do you do that?

There are many write-ups, there is s nice post on the CF as well as other places.

Search for it (you can also get the gist from the guys that use the EGR input - same deal, just a different PID).

The wideband outputs 0 - 5v, you need a PCM input sensor that is also expecting the same range, and the A/C pressure switch is that input. You unplug the pressure switch and feed that connector the WB signal while tuning.
