OFT E85 AND 93 MPG
 

What kind of MPG differences are you guys seeing with the openflash on premium and on E85? Planning on picking one up this summer. So far the car is stock, so stock comparisons would be best. Will be getting UEL and intake after though.
Also, if you go catless, does the CEL go on? With stock tune and with the OFT tune?

You know your title sounds like this "Flashed with OFT, running E85, getting 93 MPG"

Damn, I treated it like a google search, key words.

remove cat + stock tune = cel
remove cat + oft tune = no cel

e85 mpg = ~18-19 mpg, heavy driving
93 mpg = ~23 mpg, heavy driving

For me mixed driving:

e85: 20 mpg
93: 27 mpg

This makes the 50cents per gallon difference on e85 negligible.

How many cats are there on our cars, and where are they located?
I assume one in the headers and one in the mid pipe? will removing just one of them turn on the CEL?

2 cats, one on header, the other on front pipe. Removing the header cat will bring up the CEL.

I used to average about 28-30 mpg with 93, now with OFT E85 Stg 2 Im at about 22-23 roughly.

In my area:

93 is roughly 4.00/gal right now.

E85 is roughly 3.00/gal right now.

So using 28 mpg and 22 mpg as references,

$40 fillup for 93.

$30 fillup for E85.

Using the lower mpg for each:

7 miles per dollar on 93.

7.3 miles per dollar on E85.

E85 for me is more power, and more miles per $ of fuel I put in the car...which is rather crazy.
