Are EWG N55's able to run E30 or higher ethanol blends with BM3. Currently with my JB4 my trims get borderline high running E20 blends. Steve has said that even a Fuel-it pump wouldn't fix it as I would need a flash. I'm not wanting to go the meth or port injection route, but wouldn't mind doing the fuel pump upgrade.

PWG can support up to E40 Kinda useless for me to have PWG as I have no E85 where I live lol #iwishihadEWG |

I finally purchased a bootmod3 licence from another member. I have a few general and more technical questions that may benefit other bootmod3 users.and myself.
Firstly, I was under the impression 1. Ots map was included even if licesne is transferred. But it seems I'm required to buy a map? Can you clear this up for myself and other customers / potential customers? Secondly, I run 93, almost always with a tested and we'll reviewed octane boosters...Boostane, Torco, or "Racegas" , although I do not believe in ethanol in cars not designed for it(especially in a car already maxing out itsome fuel pump) I also recognize the pros of ethanol and will use it occasionally to keep the fuel system and head clean and for its oxygen content. However never more than 20%, and only maybe once or twice a month tops Bottom line, I maintain 95-100 aki, and on race day, dyno day, or dragstrip, I will use ms100, or 110 premixed with 93...But occasionally due to a lack of access or time of night, Im forced to use 93, which obviously on a now stock DME haso no negative affect whatsoever. Does the stage 2 93 octane tune add a significant amount of ignition timing advance to allow double digit whp gains with addition of much higher octane race fuel? Or will it cap it's advance to say 5* over stock (just generalizing).' On the flip side if I went with a 100 octane tune, and ran 93 in an emergency situation would the timing retard enough to avoid knock under load, or in other words does bootmod3 raise the knock sensors threshold or disable them? Also in your experience, since your Ots tunes seem to produce the most power on the M2, does the N55 in paticular prefer higher boost with less advance or lower boost with more advance in the upper rpm range? Lastly I'm assuming the OTS maps (aside from the alcohol maps) target a conservative albeit slightly leaner AFR than stock? Will it lean it out enough to avoid the fuel starvation and pump cutoff I was getting with JB4 at max boost/high rpms? OR Because of the curious decision to make the N55 a high compression /high boost engine which I assume sees dramatic dynamic compression and cylinder pressure does the cooling affect of running an abnormally rich mixture (for an aggressive tune) have the opposite effect on horsepower numbers and produce power but at the expense of fuel under prolonged load at high boost such as 5th-6th gear pulls? Lastly, from experience running open header on an engine dyno or n/a motor always has a tremendous effect on engine charteris tics and tuning preferences bc the lack of back pressure and it's dramatic effect on the way the engine runs. I found this to be less pronounced on turbo cars and also much more rewarding bc the minimal decrease in back pressure and the positive effect on exhaust velocity (faster spooling, more exhaust scavenging and theoretically more negative pressure on the exhaust side of the head making for slighlty less parasitic draw on the exhaust stroke, and more vacuum in the cylinder upon exhaust valve closure) in some circumstances..I only ask bc I run a qtp 3" exhaust dump immediately after my 4" cat less dp. Should I mention this in my tune request or is there little to nothing that can be done in terms of tune to get the most benefit bc comparing my logs to even the best JB4 logs, with the valve open, running basically open header, i see my car hold just under 20psi for 500-1000 rpms higher than the average M2 with similar mods (lower gears boost will taper at around 5800-6200.) QTP Valve shut it begins tapering by around 5k Sorry for all the technical and long winded questions, however I am picking my first Map and obviously I want to produce the most hp for my situation without sacrificing drive ability.... Thanks for your time Last edited by DKX4///M; 05-12-2017 at 09:48 PM.. |

I cannot see how a flash will be able to deliver more volume than the JB4. As far as I know it is a mechanical limitation of the HPFP.

The guys over at PTF told me "E30 map in N55 will just eat up the hpfp pressure and cause it to misfire.. So that's a no go on stock fuel system."

Given I have the Stage 2 LPFP when I asked that question, I'm betting port injection. Some folks run a small mixture on the JB4 with the flex fuel harness connected, but I could never really get it to be happy.

I've seen some EWG cars run E10 only and misfires with E15, then others handle E25-E30 (different flash tune). I've also seen most Jb4 users run a lot of E85 but not realize how lean they're running after 4500rpm at WOT. I would say start low and monitor closely your HPFP at WOT and don't forget to test your E85 content because if less than E82% you're adding more of the bad and less of the good. You would need Meth or PI as supplemental fueling if you want most power. Quote:

This is true, also the content of each E85 stations varies so will the performance when one thinks they're adding E30 for ex.
