e85 you need to be VERY carefull with , There are still NO Fed regulations in place yet to regulate the octane , if when you tune you get 98octane then 8 fillups later you get 94 your going to be in trouble big time

There also seems to be some issues in some cars about the fuel eating on fuel lines , pumps,rails etc but dont hear it as much anymore

this is me and my E85 kit i got off line www.whitelightning.net and my dad has been running it in our expedition for over a year and have 0 problems with it concerning the fuel lines and such but so far my car has been overall running much more smooth and feels like there is a slight power increase. As far as MPG loss there is a noticable amount i got 31mpg all day before on 93 and now E85 i am getting about 28

I looked at your devise and wasent impressed if all it does is plug into your injectors adding more fuel I am guessing once you hit a gived Inj Duty cycle

Problem id reguardless of what you hook in line the ECU can correct and over come these types of devises and the reason your getting crappy MPG is because they are not addressing anything in the tune itself , e85 takes diff timing , a diff targeted stoich AF for idle , cruise and WOT

Idle and cruise is done in open loop and they could tell the Inj to add 50% and if it is to rich the ECU will pull out fuel ad meet the targeted AF in the tune

You also I am guessing ar not running your car hard , Like with your Dads car just cruising around you would really see the effect of the lower octane

Doing quick math by the MPG you are loosing with the cost of the unit your not saving much if any money by using it

Not only that, but E85 produces LESS energy when burned than gas..

But if it gives you that all-over "goody" feeling for using it, go for it..

i actually just got 26mpg on my last tank and paid 2.15 for E85 while the same gas station is 2.94 for 93 so i am saving 27% in costs and lost about 17% in mpg so i am technically saving money

Now figure that math with 87 , If were going to do trash fuel lets not compare it to good 93 , lets do apples to apples

Then factor in the cost of the unit over 3 years and 87 and I think you will find your not saving anything , not even taking into the account the hugh loss of performance because your not tuned for e85

even with 87 octane it is still 60 cents less per gallon although....my car has felt nothing but improvements with all E85, much more smooth idle and when i accelerate and shift it feels like it keeps pulling. My buddy has your tune one his svt and it feels similar to that

The cost of the unit was ? 3MPG less thats a loss of 1.2 -1.5 gallons per tank so what about $3.00 -3.50 per fill up loss

How many fillups do you do a week?
