e85 is an interesting setup. One which I am considering for my 2.0 build

 

I have a question, if i want to start using E85 on my 2003 Hyundai Tiburon V6 104K miles, what do i need to do before changing to E85?

 

Don't bother. It has very limited benefit for naturally aspirated motors and will require a full retune which is probably not possible for that ECU.

 

This is good to know. I will be switching to corn very soon.

 

I haven’t read all the pages, but I’m sure I’m reiterating what many have already said. I like the power I made on e85, but it wasn’t worth the hassle for me. I run a smaller turbo, so I was only looking at around 350whp on pump and 435ish on E. it was fun, but I only have one pump in my town and none anywhere near any of the tracks I run at. This was really inconvenient. I’d have to take 30gal of the stuff with me to track days. Then there is the mysterious goo that appears in some cars. A friend of mine just had his 2.4 burn a hole in the piston because it gooped up an injector. I ran pump gas 90% of the time with occasional E to keep that from happening in my car.
Maybe if it made enough power to be worth it, I had an E85 analyzer linked to my ECU, and I was sure to run pump through it occasionally, etc.
I just like to keep things super simple so there is less to go wrong. Plus, 350whp is plenty for me. Now that I think about it, I’m probably not a good E85 candidate and not the best person to ask LOL.

 

Pearson is opening a station in Fresno soon.

 

would be nice if it were closer to my house than the current one haha.

if i had a trailer to get my car to the track, it wouldn't be so bad. driving around with 30gal of E in my trunk/cabin reminds me of a quote from my favorite movie:

"Now you're firing a gun at your imaginary friend, near 400 gallons of Nitroglycerin!"

at least i'd go in a blaze of glory LOL.

 

I <3 corn juice. Ran it for a year straight, 20k miles, with no issues..

Weird it didn't post my message.

I just said that some people have issues, some don't which makes it even worse. Nobody can explain why some people lose engines.
I like to reduce the amount of (unnecessary) risks I take. LOL.
Pump gas for me.

 

¡¿Que!?

 

LOL fixed

 

I don't see how you lose an engine with a proper tune and a wideband. If one cylinder is lean enough to blow up, you will see it on a wideband.

 

If an injector stops firing at 150-200hp a cylinder,bad things usually happen. Even if you stare at the wideband on every pull you most likely wouldn't catch it in time because it can happen so fast. Now if you have ninja skills and get lucky ,that's awesome.
Most standalones have a fail safe to try and protect the engine if afr goes over a set target. I believe the stock ecu/ tephra also has the ability for a wideband to be wired in and drop boost over a set target. Both of these methods attempt to save the engine but it's still not a 100% safety net.

 

No doubt that gunk build-up on injectors is an issue of serious concern. Another issue is that the closed loop fueling correction can contribute to hiding the lean condition on an AFR gauge. OTH, if fuel trims are regularly monitored, then an atypical positive gain can be an indicator of an issue. In the one time I had my injectors gunk-up, I found that it correlated to poor cold startup, so I use that as an indicator along with watching fuel trims. I would also imagine that misfire during cruise would be more frequent for one or two badly gunked injectors.

 

That is actually a great idea! Still, for me personally, I like less risk and more simplicity. I just want to drive the car, and enjoy it.
Good advice for people after that crazy horsepower, though.

OP asked for opinions, so that's mine. The extra power is addicting, though. Ill miss it.
