Before we know it, the E85 conversion is going to be the premier upgrade for all EVOs. First, it was the mail-in flash. E85 next...? I only have one E85 station in my location and luckily it's only five miles from my house. I plan on getting this done as soon as I can but Uncle Sam comes first. I wish I had a little more information on what exactly I need in order to get map switching with the E85 conversion.

 

Agreed. Race gas for the common man! You can quote me on that.

I'll try to answer any questions.

Hop over to the the ECUflash section of this sub-forum and read up on the Tephra 5.x ROM mod. I'm on 5.1 and it works like a charm. You can actually have any combination of two different tunes stored in your ECU ROM flash file. I have a 91 octane tune as the normal tune and the E85 tune as my alternate tune. I had a professional tuner do mine.

 

I was curious about how much I was really getting with 93-octane as compared to what I've been reading about the MPG rating for E85. I really wanted to see for myself if the benefits were worthwhile. I put 11.4 gallons of 93-octane in my car costing $3.73/gallon for a total of $42.75. I drove the car until it was nearly dry for 188 miles which means I was made 17.1 miles per gallon. Currently, E85 costs $2.99/gallon and by using the simple constant of 11.4 gallons, it would cost me $32.89. By using your 13.6MPG average, that would put me right at 155 miles per tank for a difference of 33 miles overall and saving $9.86 per tank. Granted, I'll have to fill up sooner but I look at it this way. With the $9.86 per tank that is saved, I can buy roughly 3.3 more gallons of E85. Using the same 13.6MPG average, means that I can drive an additional 44 miles which is 11 miles farther with E85 versus 93-octane. I'm not trying to say this is Gospel by any means. I was only comparing to how I drive (w/wo E85) to get a rough mileage comparison. To me, it seems as if E85 is a win-win combination because all it takes is a little patience heading back to the gas station.

 

Jim, you might want to turn the boost down a tad out there...

For now the contract mobile speed radar is only in Phoenix. I hope it stays there!

I do have a photo traffic light a couple miles from my house.
