Terry ran a cm14 nozzle on the vtt stage2 car. You will see how far you get on just E mix without meth. There is just not enough people with stage2's on n55 YET

Dead on. I have the stg2 lpfp and you can run e50 but anything above that causing fueling issues as the hpfp just cannot send that much ethanol.

To run more ethanol, take baby steps. Literally .5gal more e on every other fill-up or so. the DME is much nicer doing the gradual learn.

Also remember that e50 is not 50% e85...

Good last line.

I think a lot of people get confused about the whole thing of e50 vs 50% e85 and then you've got e85 that's actually only e70-75 because of winter fuel.

Plus the octane ratings vary quite a bit as well which changes things in JB4.

IIRC, isn't the optimal octane for map 7 103oct? On a 12.5 gallon fill up that would be 5.5 gallons of 100% ethanol and 7 gallons of 93. Which is e44 with an octane rating of 103.1

But say you do "e44" with e85 and 93 mix then 6.5 gallons e85 and 6 gallons 93 is 99.2 octane. Same "e44" but almost 4 octane points different.

I've run e60 at 20psi on my stage 2 and HPFP stays around 11 which apparently is OK but you wouldn't want it to go much lower.
But it seems to run more consistently on e40 or 50.
Like everyone says work your way up gradually and log, everyones car is a little bit different.

For N55s I've found they prefer to run lean, and don't need a lot of extra fueling, even on E50. Maybe a CM10 or CM12 nozzle is enough. As always you'll need to review your own logs to verify.

Terry, what is your take on the octane side of things?

I have a station near me that is a blender pump that has E30, E50 and E85.

If I fill up my tank with their E50 I'm almost sure it's going to be under 100 octane, whereas if I use a mix of 100% ethanol and 93 octane I can still be E50 but higher octane.

I was under the impression this makes a big difference but never see it mentioned. Just the E__ numbers.

Pretty damn excited. Went to Cobb in Plano yesterday to have them see if their AP would flash my 2012. It took perfectly. Sales guy helping me showed me how to add maps to the AP so we put the BMS flash from the first post in here on it.

There might be some placebo effect but just from a couple highway pulls and driving around town the car seems to pull a lot smoother. I'll have to wait till I get back to KC and it dries up a bit to do some logs but so far I'm really happy.

3.5bar tmap sensor is waiting for me back at home so that will go on soon too.


I've read through this entire thread so correct me if I don't have this right. With this back end flash I can do a 50/50 mix of e85 and then do some logs then if it needs any tweaking Terry, you can help out with that?

You can use map 5 with E30-E40

With E50 and methanol injection map 7 should be fine too.

You can post logs in the support section and myself or Russell will help check them out.

When you start mixing E85 with pump fuel your really mixing three fuels.
1. The pump fuel you add to complete the fill, normally 91 to 93 octane.
2. The pure Ethanol in the pump fuel and E85.
3. The gasoline that makes up the balance of the E85, E50 or E30.

The problem is the octane of the fuel that makes up the "balance fuel" when you purchase anything less than E100. Do you really think that octane is anything higher than 87?

Thanks Terry. I have a couple logs to post up when I get home in a bit.


Russell, yeah it seems the best solution is to hopefully fine e100 somewhere and fill a can so you can mix it yourself. I'm sure none of the stations blend their E with anything but 87.

I tried both E100 and E96.6 bio ethanol. It made no difference. Now I get straight ethanol (not bio version) from the chemist at only 1.20 euro per liter.

Ethanol is ethanol and both are technically considered "bio" because of the way they are produced.

http://cta.ornl.gov/bedb/biofuels/et...Overview.shtml

I originally looked at the 96.6% ethanol but quickly learned that the remaining 3.4% in that blend was mostly distilled water. Needless to say, I didn't want to take any chances with it in my tank.

So I got an Accessport V2 for my N55.. It's a 98G0B car, but the AP says it's an unknown ROM. AP is updated to latest firmware level. Am I missing something, or do I just need to contact COBB tech support? Thanks.

You need to enable beta firmware in accessport manager. After that, firmware should update. Then hook it up to your car and it should work.

Thanks for the reply. I found that after my post.. Tried it, hooked it up to the car with the same result. I sent COBB an unrecognized ROM form with my ECU ROM file attached. Guess i'll see what they say. I suspect it has something to do with the PPK flash? Who knows..

Flash maps for 2011 - early 2012 models are in the first post. There are no flash maps for mid 2012+ models.
