Speedy's Garage Race E85 vs Pump E85?

Stuff I use:

This week at Speedy's Garage I take a look at how pump E85 compares to race E85 purchased in drums. The biggest difference between pump E85 and race E85 is what the 15% "other" material consists of. Pump E85 can be almost anything for that 15% where race E85 will be a high quality hydrocarbon (like race fuel). I was curious how the Dodge Challenger Hellcat Go Man Go would react to race E85 on a pump E85 tune.

I'm jealous of this garage. Nice man, love how put together everything is.

Afrs and gas changes is why i perfer to tune in Lambda. 1 is 1 is 1. No matter the gas.

Lambda confuses people at first but once you get use to it its amazing. Its why i love my aem series x widrband, and my fueltech wideband set up. Both can be changed to display lambda

Thanks for the info...I'm learning all about the tuning frustrations of open loop/closed loop and trying to keep my supercharged 03 tacoma happy.

Man this guy is sharp. Best e85 understanding video on YouTube. Good job.

Thanks for the video. I’m boosting my turbo civic. Just want to run 1 gallon of e85 to full tank of 93. Adjusting the afrs get my confused right now. Seems like I need to just add more fuel in the table to compensate.

Another awesome detailed video I really appreciate the info you share helps me learn more and more about my hellcat and since I just switched to E85 this was perfect 👍

I've been running E85 in my F2 Procharged '69 Camaro for over 5 years. Where I live in California the E85 at the pump always measures 90% or better on the ethanol content. I checked it periodically during the first 6 months or so and then stopped. There's no reason to continue checking it.

My man is shaking like he ain't had a drink since 0930.

I’m running a stand alone wideband I’m tuned on 91 pump with 50/50 water alcohol injection and see 10.5-10.7 afr I have plenty of pump and injector what if I run 91 pump and e85 to get a mix of E30 would I see a leaner af at wot such as 11.5?

Great video as always Jay! But after all that talk of numbers, my brain is….🤯🤯🤯🤯🤯🤪

[jackbrown-lqdu]

Did you dyno test to see what the difference is between e85 and pump gas
my setup is similar to yours.

[statichorse]

In HP Tuners. Go To Fuel. Then to Temperature Control. Look at FA Enrich Max. Tell me what you see

Hey Speedy's Garage I am in bell buckle TN. would like to link up one day is there any events you are going to soon?

[RAWRMotorsports]

13.85? E10 is 14.2 stoic .. Why you running so rich at cruise? Safety ?

Do the Hellcat tuners lower the AFR on our cars using pump gas for the cooling effect? I know I hear 11-1 as a good 93 octane AFR. My car was tuned into the low 10s on AFR but I figure it's because of the higher boost level than normal on pump(17lbs). I have to be giving up some power running this rich but right now I am not running the car hard and have E85 mods in future plans. Right now I just need a dual pump since I already have KB Boostapump, bigger injectors( currently 1050x's in the car), and a couple of smaller pulleys. I will be porting the factory blower through Kong and going with a 108mm throttle body. As a safety measure I might throw a Meth injection kit on it. Going to probably let Dusterhoff tune it. I like Barth but I want to use HP tuners since it will allow me to make little changes.Ronnie Fowler has a big power Charger (1300+) in Smyrna and he likes those two. His tuner does race tunes only. I've talked to Barth in the past and he was very helpful.

Hi Speedy...not exactly on subject but I have been wondering how changing tunes would work if the tune is "locked" meaning you purchased it from a tuner who locked the tune. Do you have to contact the tuner every time you want to put a different tune into the ECM? If you are changing the OEM tune yourself, it appears as if you pay to get the computer unlocked (depending on the year of your model) and the required number of credits, then after saving the OEM file, you make your changes and download/write it back into the ECM which you can do as many times as you want for your car. Thanks

Hey Speedy... what is that funnel you're using. I'm dumping a little 109 in my 1320 and don't want to get any fuel on the paint.
You have a link?

[joshsmitsky]

Speedy, I live in the Pittsburgh area. I’m using ost for my flex time tuning, mike said the flex sometimes is “finicky” . Would you recommend the 2 separate tunes or just the flex? Love the channel. We basically modeled my build off your channel.

Is there a shelf life on E85 race fuel? very informative video, thanks 👍😁

[calbusa]

Hey speedy
What did you find to be most helpful in learning to do your own tuning?
Thanks
