Friday or monday, depending upon work will be my first E85 trial, gonna keep everything consistent and do a full tank of a E85 30% to 70% 93 tank..

i started with a 30% blend first... logs looked great.. and now with 50/50 they look even better!

[07_335i_AW]

I run 50/50 as well. Last time I added 5 gallons when I was at a 1/4 tank so my last mix may have been a little stronger on the e85 side. Runs AWESOME!!

60/40 has been working well for my ride.

its funny guys will throw in race gas without thinking about it but when it comes to E85 guys are all worried.. if anything the E85 is easier to work with since we are mixing it.. a few gals of E85 is no big deal with map 5

Huh? Race fuel and e85 are similar but not identical. E85 needs about 30% more fuel and these cars at the moment are just keeping up with fuel requirements. That's why people worry about the ratio, they don't want to run lean.

And ethanol is horrible for everything inside your fuel system

I agree but I think that is a very long term effect and not a fast acting problem. but I couldn't resist trying a 60/40 mix and it runs great but the car smells like a factory from the combusting ethanol.

i understand this.. but E85 has been shown to be safe with this tune.. but guys will run 100% leaded race fuel on map 7 with no worries? were all taking a risk i understand this... E85 makes more sense to me especially with the Autotuning

I personally have yet to see anyone run leaded race gas on the N54.. E85 is alot different then your regular high octane unleaded race fuel or 93 octane pump...
N54 fuel system is prone to failures at the LPFP and HPFP along with the injectors, adding E85, which in volume needs more to push and is also known to be corrosive.. That along with this car not being solely made to run on E85, these mixes might just be a bandaid to something that might go wrong with E85.. This is speculation but being on the safe side of running E85 (mixing and low levels of mixing) on a platform like this is a good start.
As for safe running tune itself, The E85 is def a safe running tune. Provides higher octane for better timing and higher boost, along with provides better cooling benefits. E85 has always been great for tuning.

I dont think anyone knows yet how much damage running E85 is really doing on the internal parts physically but looks like at 50% mix or less, its holding up well currently. Then again this is the first time a wide range of N54 owners are using E85.. Only time will tell.. Also interested to see carbon build up after using high mixes of E85.

Do you expect the carbon to be worse or something because it really shouldn't matter. Also, I'd be curious to see the design of some ford vehicles that are built for e85 and what the difference is between the same cars standard 87 gas fuel system. I can't imagine its an entire fuel system overhaul. Why would the injectors be likely to go on the n54 because of e85?

Well i would imagine a e85 car has components installed that will withstand the corrosiveness of e85 and the proper hardware to push the extra volume of e85 at sustained levels in a reliable manor..

As for the carbon build up, the n54 loves building it up... If e85 will accelerate the build up is something i look forward to see..
As for injectors, there failing on stock cars and regular pump, e85 needing more flow is going to work them a lil more and the lil corrosiveness could be a issue for the injectors?

But like i said no1 knows, its speculation.. Gonna be interesting to see down the line.. I plan on running it monday on a full tank.

Just got back from a nice long drive and I'm loving the new map 5. When I first installed the jb4 I only had a 35-40% e85 to 91 ratio and the car felt pretty similar to cobb stage 2+ aggresive. Took me a while to get used to giving full throttle to get full boost, as I had been running the ST map on cobb where roughly 60% throttle would give you full boost.

So today I filled up with 5.5 gallons of e85 and 5.5 gallons of 91 to try out a 50/50 blend. Roads were dry, but I was able to get the traction control light to flicker in not only 3rd, but also 4th gear. Never has that happened when runnning cobb. Acording to the indash boost gauge I'm hitting 17-18psi and tappering to about 15psi. Timing looks good when using the oil gauge. Need to send some logs into terry but Ive been to lazy to dig the usb cable out of the ecu box but I'll get around to it tomorrow. I'm going to see if I can load the stock map using my cobb and run the jb4 map 5 and see if I can use the performance menu to do some 1/4 mile runs.

So anyone on the fence about trying out the jb4 I say give it a go. I was just tired of waiting for cobb to release their meth maps, and didn't want to get a pro-tune until someone else can show the gains made. Also I ordered the jb4 with the 15 ohm mod, can't wait to have my HFS-4 installed!

Finally got a chance to test out the new map5...
It feels snappier and more consistent, it wants to free rev down low more easily.

But on a FBO car, Fully catless, ETS FMIC, DCI, on 93 octane pump, NO meth/racegas or E85, the car on map 5, peaked at 14psi and by redline was at around 9 psi.

On my regular map 2, peaks at 14 and at redline is a around 12 psi..
Map 2 also feels more powerful where the map5 top end dies off.

Like i said this is on pump 93 octane on a FBO car. No meth/race gas/ E85..

Looking at the logs, the Map5 log looks better and cleaner, and will def. be more consistent but seems less powerful for my setup..

Gonna try E85 mix and do more logs.

I have FBO and had 93 straight and hit 16 psi and tapered down to 14.5 and With a E85 mix (40/60) hit 17 and tapered down to 15.

[rdeterman]

while logging i notice ~17.5psi peak and ~12.5 at redline.. on new Firmware with 50/50 91/E85 mix map 5

Are the boost levels u stating after good adapting? And just pump gas alone?

My boost reading are from my logs on map 5 and pump alone after it being adapted..

Wanted to get a baseline feel for what map5 can do on pump alone before adding e85/race gas and turning on the meth..

But seems like on pump only fbo and 93 octane map5 is weaker then map2 for me

YA try the E85 and report back Should be a significant boost increase on map5 for you.

Hey guys on ma way to get e85 i have 3/4 quarters full of 93 of my tank... I was gonna add 2-3 gallons of e85 what % would that give me??

I basically have a quarter of a tank empty..

it would give you 2-3/15th of E85

It is best to mix with a empty tank (1/8th)....I can usually fit in 14 gals of gas from there so a 30% mix would be 4.2 gals of E85 and 9.8 gals of 93 and a 40% mix would be 5.6 gals of E85 and 8.4 of 93. I usually put in the E85 first then the 93 so it mixes better.

I would do a couple of 3rd gear WOT runs for adaption.

[barton2002]

how much more gain and wt psi should i be expecting if i am not running it with e85?

and when u say adaption, do i jus go wot a few times n let it learn by itself?
