That would explain small injectors and able to use just the one 044 pump. I mean, as compared to a 3.3ltr running E85 which will use a lot more fuel than petrol. While there are a few things you need to change to run E85 it really isn't a problem...except some varieties of E85 can gum up the inj's. Ironically, mostly the supposedly Race Grade E85 vs the stuff out of the pump. Never had a problem with pump version but with the race stuff, we keep 2 sets of 2000cc injs and just clean them each time they come out.
Maxxtuning that manufactures MaXX ECU here in Sweden used to have issues with injectors clogging up when tuning cars on E85. They then started using this product http://www.maxxtuning.se/produkter/o...medel-i-tanken and since that no more issues. Maybe a thing to consider for you E85 users. Supposed to put one of those bottles in the tank every oilchange.

I'll say that I think e85 already saved my motor by being very forgiving while going lean. Definitely want to keep running it although will stick to pump. Race e85 is 9$ a gallon vs 1.50 at the pump. I'll just keep the timing conservative. Should have unreal power regardless

I see your running dual 44s with a surge tank right? Hope the Fuelab works out, it cost me a ton

We also have an ethanol sensor in the fuel system setup. Put that in before I decided to go with the Race stuff. You can then run this through the ECU and adj timing to suit. Might be worth investigating that for your car?

Flex fuel is really easy to add, most ECUs have a sensor input for it. It will interpolate tables, for fuel trim and spark advance. You can also use it to monitor fuel temp (coming out of the rail). I ran one in my NA car as an experiment and it's going to my 951 now.

When i ran E85 i was living in sweden and had it everywhere. The mix blend was inconsistent at best since i am running a VR MAF system i had to deal with FQS all the time and rarely open the ecu to change the map. I gave up for a bit and bought 204Ltr Racefuel Ignite E85R, wow what a difference dead on 85% and tune once. cost allot though about 710USD

I plan on adding a flex fuel sensor for this reason, but first I need to get enough fuel to the beast before I worry about the quality of the fuel.

Y'all probably have better QA/QC there. Here E85 means that ethanol will make up no more than 85%. In actuality it runs anywhere from 45% to 65%. To run E85 I was advised to blend it my self for best results, this was a hassle I could do with out. I was looking at getting to sets of injectors, but in the end decide to use gasoline.

I would wholeheartedly disagree with that assessment. I've tested the ethanol content in multiple states and haven't found anything like you're describing. Currently I'm in south Texas and the pump E85 is testing right at 85% consistently. Colorado was also very consistent depending on the season.
I agree completely. I have gotten E85 at 5 different locations and found it to be very consistent.

I was always under the assumption that pump E85 varies the ethanol % content based on seasons?

How does Shell ClearFLEX work?
Shell ClearFLEX is comprised of up to 83% ethanol and 17% gasoline as required by strict US government standards, and is visibly clearer than gasoline. Shell ClearFLEX is the only alternative fuel that can provide you with the high quality you have come to expect from Shell. Try Shell ClearFLEX today
From Exxon's Website
Ethanol flex fuel (formerly known as E85) has between 51 and 83% ethanol with the remainder being gasoline.
From the gov't website
E85 (or flex fuel) is a term that refers to high-level ethanol-gasoline blends containing 51%-83% ethanol, depending on geography and season
I cannot find the Houston Chronicle article on E85, but it showed a significant variation in ethanol content in Houston between refiners.
Please note I was looking at doing this 1 1/2-years ago and QA/QC may have improved. I made my final decision on the recommendation of my tuner who is one of the primary ethanol tuners in Houston.

In the colder climates, yes they go to 70%. Tha'ts why I mentioned season in Colorado. Down here, we don't have a cold season really , so it's consistent 85%.
I'm going off of my measured experience in 4 states.
