I’m not even sure how that could happen. Is the flash completing too 100%? Can you give us more details?

I never had any flash issues, but if you are I’d at least ping PTF.

Thanks.. ill reach out to them.

ZM2...All I can say is WOW! Have slight stutter under heavy load during logs.(maybe fuel quality?)but overall, huge improvement with adding dorch hpfp.
Hitting 20 target psi and target hpfp

Hahah. Yeah, the map is a blast!

What Emix are you running? Can you post your logs so we can see/help remedy the stutter?

Mixing 2.5 gallons e85 rest 93..

2.5gal of E85 and the rest of the tank is 93? That's not enough E85.

You need almost 4gal at a minimum and up to 5gal if your flex fuel E85 is lower than 85% ethanol content. I usually just do half E85/half 93 to make mixing easy and that lands me ~E45.

I'll take a look at your log in a bit, but add a few more gallons of E85 and see if the issue goes away.

[Wheats1]

Dang. I thought e30 in our tanks is 2.5 gal e85 then filling up with 93 .
I'll increase to 4 and log.. thanks

[Wheats1]

Here's another log if you can check.same day.. Thanks

Brew City Boost has a simple online E85 calculator that you can use for quick calcs. Just remember that most E85 pumps in the US are flex fuel and tend to average bn E70-E85, vs the high quality E85 found in other countries.

When I ran the Stg 2 E30 map on the stock HPFP I used apps like CalculatE85 to estimate a certain Emix in the tank between fill ups. With the Dorch HPFP, I just go half 93/half E85 to keep things simple.

Reviewing them now. What mods do you have on your car? Did you also do anything with plugs or coils?

EDIT: First log isn't worthwhile; you're not WOT until 5k RPM and you're not running the car to redline. Second log isn't worthwhile; you're only WOT from 3-4.5k RPM.

When you log after adding more E85, go WOT from 3K-redline. If you don't have the room to do that in 4th gear, do it in 3rd gear.

Hey Man, did you check ethanol content in E85 pump? I'm in Chicagoland area and currently I only have 73% on the pump. You have to test it before doing your E85 calculation. ZM2 and I worked a lot on this map and the best to run this map is E50 mix which the couple of forum members and Halim confirmed it. This map works great as long as you have the right HPFP pump, fuel mixed and 3.5 bar TMAP sensor in place, you should really enjoy it. I have been so happy to run this map but can't push too much because Chicago winter now. Can't wait to open it up in spring soon!

[Wheats1]

Yeah, I figured regarding logs(wot).. ill get the e85 right this week and data log again.
Mods: 5inch stepped intercooler, sportcat dp, vrsf charge pipe, drop in filter.. dorch stage 1 hpfp
Stock plugs and coils.. 16k miles

[Wheats1]

Weird thing is.. when I ease into throttle to wot to 6.5k its fine .. no stuttering
Just when I mash it spiritly..lol
Any other map its fine as well

If it still does it after you add more E85, try to capture it in a log and we'll all take a look.

[Wheats1]

Awesome. Thanks

[Wheats1]

ZM2.. went and added 3.5 gal of e85 and topped off 93. To make 6 total, and I did notice a big increase in throttle response. Tried small wide open pulls in 4th and 5th without any stuttering. Its 73 and rainy (tampa area)now so I can't really get any logs in today. Its seems the lack of e85 was the culprit. Ill log this weekend and post. Thanks again

Great to hear!

Your previous mix was E21-24 which is way too low for this map. It’s labeled E30, but just as JKen_0115 said, even E30 seems low in the logs and guys are having the best results E45-55.

Just cleared the snow off my car, put E50 in the tank, and drove it for the first time in a few weeks.

Man this car is a blast!

Zack, I'm glad to hear that and I haven't seen the drop in my Dorch STG1 in the cold weather so far. E50 is the way to go man!

ZM2.. my installer said thats probably exactly what happened when I went wot..
He also said running too little e85 in that map could be a good way to kill an engine, regarding cylinder heat.. yikes

Yup, you need to have the proper fuel and mods for any of these maps.

The good thing is it was wet and you were easing into your initial tests, so you didn’t spend much time at WOT and caught it early.

Gotta love $2.xx/gal race gas. I’ll buy all the E85 I can! Heck, even after accounting for 30% less energy content per gallon than 93, it’s only a 13% cost premium versus pump gas here. Whereas 100 octane is more than triple the price of pump gas!
