E85 FBO retune

[Steve8989]

From a prior post I did that was a short clip of my cold start [ sounds like shit tbh ] I'm having trouble setting up a re tune with the performance shop I had the work done and tune, the tune is from ortiz performance, love the tune but that horrible cold start up was never addressed. Contacted ortiz performance and since I don't physically have the tuning device they can't do anything. What good options do I have, and what good shops are around NW indiana 46307, and as far as Chicago Illinois. Just want this shit tuned out so it sounds good. [ after its warmed up and then started say an hour after its completely normal ].

Probably start with getting another tuning device lol

Ya, but my main thing is who to go to next, use Ortiz performance again or go a new route is more the question I have. Because I don't understand why this wasn't tuned out to begin with or why it wasn't even brought up.

My cold start idle fluctuated quite a bit with my Ortiz tune. He had trouble tuning my IMRC's too. I'd look elsewhere.

Didn't you have borla atak catback and long tubes? Do you still have that set up?

The correct answer here is you shouldnt be running E85 in any climate that gets below 40s-50s. E85 cold start tuning is a tad tricky because you really need to flood those cylinders with fuel to get it to pop off as good as 93, but the catch is you arent going to realize any benefit of E85 in the winter. You got perfect air already, cold fuel and no traction. Why do you need the extra power and less gas mileage of E85 over 93 when you cant use it anyway?

Then you cause all kinds of static between you and your tuner talking about not being able to get it to start right when you are doing this for no gain. I already see someone talking about ortiz here and saying you should look elsewhere. My opinion having tuned 500+ gen3/4 cars just last year alone is you need to switch back to 93 in the winter like most reasonable people and not push this subject to the point where you are looking for a new tuner, trashing your old tuner and also having to spend more money.

Do everyone a favor including yourself, and just use 93 in winter if you are in a climate that gets below freezing. Its just not necessary to run E85 especially when you are likely getting winter blend anyway which is always garbage.

Now if you are in say FL and having cold start issues in temps like 50-70, then thats a simple fix that shouldnt be hosing down the cylinders with excess fuel and washing them down.

If my block temps are much below 50F, my E85 cold start will ignite a few times, then stumble and stall on the first attempt. Second attempt it lights off perfectly. Just needs a bit of heat in the chambers to help vaporize the ethanol. Went back and forth with Shoemaker a couple of times and it is what it is. Not his fault. Just physics and chemistry.

Unless someone here has experience/knowledge to the contrary. Perhaps adding more DI fuel in lieu of PI would promote better vaporization?

Id recommend getting a device and you can log it for Ortiz and get the cold start fixed I can help with getting an RTD out to you

He's looking for a tuner in NW Indiana or Chicago. It's cold AF!! there right now. Hopefully he heeds your warning and returns back to 93. to save himself trouble and money.

Why dont you have the tuning device?

 

[GrabberBargeCaptain]

Im guessing the shop used theirs.

My E85 tune that I got through Sean at AED fires right up even in cold temps. I had the same issues on cold start E85 as OP with another tuner that I originally had. I never had them address it since I figured that’s how E85 tunes are in cold temps. So was pleasantly surprised when I got this tune.

Just asking as I’m not a tuner but if I’m at the track, it’s 40-50 degrees and have traction. Is the E85 tune not a benefit?

It sure would be. You know what won’t be of benefit, cold start performance. Watch a cold racecar try and start in 40 degree weather at the drag strip. Takes a few cranking rounds in most cases.

If a stock flex fuel 5.0 F-150 can cold start just fine on E85 (they do, I have done it multiple times this week/month and I am not alone), a 5.0L Mustang can do it too. I am currently running full E85 in a stock 5.0L F-150 that has OEM flex fuel and it's been in the low 30s every morning this past week. No cold start issues. Zero. It simply starts up, and I drive it.

My experience is the same with my Mustang running E85 in even colder temps. If setup correctly, it just works.

Find a new tuner. These aren't race cars and they can be dialed in to cold start on E85 with minimal effort. Anyone telling you otherwise is wrong.
