I am newbee to your forum and I'am interested in purchasing a U7194 for my '07 LT3 Avalanche,equipped with a 5.3 Liter Flex fuel motor. I have already installed a GM performance CAI and a Corsa touring ehaust. I plan to run E85, when I can find it, in it. I was wandering if the pre-programed tunes on the U7194 will also work as well with E85 fuel? And, E85 and gas fuel mix?
If I am looking for MPG's over performance, which existing tune on the U7194 will work best?
If I was looking for performance, which tune would work better?
Or will there be a tune available that will work with both E85 and Gas?

Use of the 93 tune will be fine with the E85 or gas in the tank.

Thanks for your response, Mike. I was also reviewing the lastest info about update downloads for the U7194. What would be the latest download (v9r03) that well work with my 2007 Avalanche? Thanks in advance.

9r03 is the latest and greatest....

Will the 87 tune also work well with e85?

Yupper.

Guys, get a CMR dealer who really knows what they are doing and have them do a custom tune with E-85 in. Great power is available if they take advantage of the extra octane and know how to use the extra oxygen in the fuel.
