My original plan was to run a 2 tune ecu and adjust the boost between e85 and 93. At the time it still sounded like there was a struggle with getting injectors to flow enough e85 and idle on gasoline. But maybe not anymore. I have a punp half a mile from my house. A few small fuel adjustments with lines, pumps and injectors and im ready to go. Maybe the end of the year ill pull the trigger.
Does anyone test there e85 to see what mix is currently at the pump? If so do you make any adjustments or no?

It's 39 vs factory 16.8 so 22.2 gallons more than factory fbody, so roughly 165lbs more weight than a an fbody tank full. It doesn't drop the supsension that much full vs empty, not as much as you would think, it's mounted right above the rear end so the weight isn't real far back.
Edit: I should also mention four 5 gallon gas cans fit perfect in the trunk, giving me 59 gallons fuel if I really needed it for a long road trip, getting 18mpg as it does cruising on the highway will get me over a 1000 mile fuel range! If I can't find an e85 then with that range...guess I'll just give up lol.

In my turbo car I loved it. In my NA big motor car not so much. ******* averages 11mpg. With an 18gallon tank. And I try and drive it everywhere. Except work. Which means many many trips to the gas station.

I love it! I just wish I had a bigger fuel tank. I am going to have to build a custom cell like Skinnies. Mine is only 12 gallon cell and I only fill to 11. Thank goodness I average 17mpg. Of course they sale it everywhere around here. Usually less than $3 a gallon for 105 octane and runs so cool it allows you a huge tuning window.
We are working on two fuel system setup on maxx's 3rd gen, will be able to cruise on 87 octane and as soon as it gets into boost tips into e85 on the fly! Should be able to pull some GOOD gas mileage on the pump gas side cruising!

I would also like to know how to do this. I want to switch to E85. we have 2 stations. But i wanna b able to switch between 93 and E85 for trips or emergency. Say u get below a little less than a 1/4 tank of fuel on E85...can you just switch the tune to 93 and fill her up and go and vice versa, and how cam u switch tunes on the fly??

Is switching to the holly ECU pretty involved or is it plug and play?
and is it literally just a **** to pick your tune? Also, does hp tuners work with the holly ecu cuz that's what my tuners uses.

I don't monitor my tune at all. I had a professional tune it for WOT and I just watch my LM1 when I romp on it and make sure that my AFR is under 11 when at full boost. I also run low timing of 16 degrees at full boost, plus not too hot of a plug. NGK 7. Not saying it won't blow up but I don't baby this by any means. I have made 2 hr trips with it and raced a couple cars on the freeway and without even running my fans it rarely gets over 170 degrees on the temp gauge. When you check the engine after a 2 hr drive I can put my hand on the cold side and it is just luke warm to the touch. Where as the turbos and exhaust are hot as hell!
No, HPTuners and Holley EFI are two completely difference systems and are not compatible. HPT is for tuning your factory ECU. Holley is it's own ECU and software. It's more involved in the sense that you have to remove your complete factory engine harness then plug the Holley harness into you factory sensor and solder a few other wires. You also can't run your factory gauges with the Holley. BUT, Holley has an auto tune function where can do 90%+ of your tuning on your own on the street or strip AND you can have a dozen different tunes and one click will load it.

The only thing i dont like about it is having to make special trips to the gas station... but thats not that big of a deal.
Im running a blow through carb on mine, with NO intercooler, and after a drive my intake manifold will be ice cold to the touch. it will be sweating like a glass out ice water left out on a counter, on a warm day.
I think once i may even of had a little frost on it.
