Thoughts on these $300 e-85 conversion kits

[Ask92]

I would have put this in OT, but I want it to be a halfway decent thread.

Someone recently sent me a link to this kit asking if this is the real deal or if it is just another electric supercharger type of thing. After looking into it a bit more it looks like it is just basically a box that changes the injectors duel cycle makes them work harder to pump more fuel in. It obviously wont be good for anyone looking to make serious power, but it may be a viable option for OEM guys to run e85 without shelling out the cash for a EMS. Anyone have any thoughts or experience with kits like these?

This will only adjust fuel though, the main benefit of e85 is the increase in timing. There really is no benefit to e85 if your going to change nothing with the tune of the vehicle except injector duty. Its cheaper fuel but you use more per mile. Its like filling up a geo metro with race gas, it would do nothing, probably even run worse without adjustment to the timing, but you could tell your friends it runs on race gas.

I disagree respectfully. Guys running a stock Ecu already see more timing than most with an aftermarket Ecu(takes care of adding the timing) so really all the piggyback guys need is a way to add more fuel(although jacking fuel press is also a good way,, but not always enough)
There's a ton more to it than that, but don't forget piggyback guys have been doing fuel only tuning for many many years and its still one of the best systems out there imo and Damn sure reliable

e85 is about 30 percent worse in consumption compared to 91-93 pump right? Couldn't one say that the difference in price to 91 ocatane IE here in CA which is 4.30-45 a gallon atm be offset with the performance increase with the only flaw being more frequent fill ups? Basically they somewhat equal out in costs since last I checked E85 was around 3.50-3.75 a gallon. So couldn't you almost drive as far with the same amount of money being pumped in your car of e85 compared to 91 pump?

my e85 supra with 1200cc on piggy back runs like oem lol.... only draw back is when i reset the ecu it takes awhile for the ecu to relearn it self.

In a word... NO.

Your math, that you have not done is wrong.

According to e85prices.com the average price is 3.66 for e85 and 4.23 for 87 according to californiagasprices.com. In 2000 miles if you average 25mpg on 87(not a supra obviously) you will use 80 gallons of fuel. 80x$4.23= $338.40. Same setup, you'll get 17.5mpg on E-85(-30%) and use 114.3 gallons of fuel. 114.3x$3.66=$418.28. So yes E-85 is more expensive overall, but for performance applications it is obviously much cheaper and more readily available than race gas.

Obviously because Supras already have to run premium and generally have crap mpg the gap between the 2 will close a bit, but not much.

Guys I don't want this to turn into e85 vs. Conventional gasoline thread , there are plenty of those already. I don't think people will be converting their everyday cars to e85 to run more boost, or to cut down costs but more to "Save the planet"(Yes I know e85 is very energy intensive). I was mainly looking for peoples overall thoughts on these kits and if anyone had any first hand experience with them

correct.

let's say 4.3 / gallon 91 ... 50 bucks gives you 11.6 gallons
let's assume 15 MPG ... 174 miles

3.5 / gallon E85 ... 50 bucks gives you 14.3 gallons
let's assume 30% worse MPG -> 11.5 MPG ... results in 164 miles

In a word... NO.

WHAT? how about you do the math?

If your not into the technically eco friendly peace of mind. It is the best race gas you can put for 800whp not sure if I would go higher safety wise. E98 for anything more though I will just for kicks use Q16 when I am ready.

To keep your parts lasting longer with E85. Fuel pumps, injectors, internals. If you plan on going on a 2 week vacation, or storing it your car for winter. Put 2 gallons of regular pump gas, or premium in a empty gas tank. Turn the car on, and let it idle for a couple of minutes to push the regular gas inside the engine preventing moisture damage from the E85. More tests needs to be done with oil, but I hear amsoil is the best for E85 with the same changing intervals. Custom build your own fuel kit to save money.

We shouldn't be talking about E85 for fuel economy reasons, although I get about 10-15% less per mile during normal cruising than I did with pump fuel. The true benefit of E85 is that it performs better than C16 for a fraction of the cost and is readily available, at least here in the Midwest.

I just filled up last week, $2.99 here in Utah!

^ Go read all 7,060 posts again puss cake. The math is wrong because the units you are working in are not correct. Race gas vs E85 ... no one goes to E85 for the cheaper price over 91 and does not re tune the car and turn up the boost. You need to learn to read kid.

Its all about E85 vs unleaded race fuel. If you wanted to do the math on this you need to find a few things out. Ethanol has about 115 octane and E85 has 105 octane depends on the mix and location you are in. Here in San Diego we get 105 E85 at the pump year round it will never change.

7059 of your 7060 post are bullshit - you really dont know what youre talking about. you NEED to learn to STFU!

The point is E85 is not worth it in a cost saving perspective, after you figure out the cost of the compatable fuel lines, injectors, pump, EMS, and tune you are way way deep in the hole to save any money versus 91 pump. The benifit of E85 is when you take into consideration the cost of race fuel, the debate between E85/91 pump gas in regards to cost savings is a moot point.

I myself use methanol and 91 pump, its cheap and does not require me to change out my whole fuel system.
