So what was changed in the update ?

 

The interface got a minor facelift. The main page appears to be a M8 motor with a "screamin' eagle" AC. There's a dialogue box that pops up whenever you open the program that asks if you want to use the "tuning guide." Seems to be an update to make it a little more friendly for end users and some updates to the interface that make the program a little more user friendly.

No major update and, yes, you can still change the a/f ratio to whatever you would like. The sky isn't falling and this update looks like it was probably in the works for a little bit and not just a knee jerk reaction to the EPA nonsense.

**that is unless they wanted to make the program easier for the home tuner because people won't be able to get them tuned at the dealerships anymore.. which is actually a very good possibility.

Tuning files are .dt0 files.
