^This...you had it right.

If you change your mix....change maps and then change back to map 5 so that you reset your adaptions. Do a few 3rd gear pulls and you're good until the next time you change your mix. It doesn't matter if you switch back and forth between mixes as long as you do as I described after filling up.

You can alternate fuel mixtures as much as you want?

I recently was running 100% e85, then went to a blend of 50% e85 with 50% 91 and last night I put in 5 gallons of 100 oct for some testing.

This is the beauty of Map 5. It learns what the best result is.

Now as far as performance is concerned, it will vary depending on the fuel mixture you have, ambient conditions etc.

Mix away, just expect to have various performance changes.

I've personally just left it on Map 5, done 3-4 adaptation runs and it was fine. I think the critical part is to do the adaptation runs.

But SteveAZ has probably forgotten more than I'll ever know about this platform.

My guess is that changing from Map 5 to Map 'x' and back to Map 5 does a force reset to defaults. So maybe speeds up the process?

I tried running 100% e85 when I had stock snails (on Map 7) and it was ok, although I was hindered by fueling.

I don't think I'm the norm though. I'm having a range of fueling issues that I'm working on.

I believe SteveAZ is running 100% e85 and is currently tweaking a solution for reliable e85 driving.

I daily drive on map 7... its no big deal. Map 7 works with E85 really well as long as you have the backend flash

I have the BMS flash and run 100% e85 with no real issues...yet

No fuel mixture codes, just this 2aae code I get, but I've changed out the HPFP LPFP, next i would assume is the fuel pump module and/or new software coding. Going into the dealership soon to have them look at it.

Note, the code doesnt hinder any performance at all, logs look good.

Only thing is the partial throttle, seems like when it gets close to shifting gears, it hiccups

You do know I'm completely envious.

I'm onto my 3rd lpfp setup 'fix' and 2nd hpfp setup 'fix'.

Ok I dont feel so bad.

Noticed you are in San Jose. Next time Im out there maybe I can take a look at the car and see your set up?

Absolutely. Depending on how long until you're out here next, fingers crossed, I'll have the fueling fixed and will be RBs on 100% e85 with 100% meth.

I run a modded BMS file on my Cobb AP that has boosted torque conversion calc tables. This is to force the transmission into quicker, crisper shifts. It's definitely better than before, though no Alpina upgrade. I also raised the shift reduction in JB4 to 75.
I plan on tinkering with it some more, just haven't had much to me lately due to vacations, house guests and various other stuff. I will be logging and tweaking with Terry B who provided that file for me.

For a while I was chasing the idea of an Alpina flash for the transmission. But after a long hard search that led me to an Alpina B5 owner and TCU identification, it turned out that the B5 is based on the transmission used in 8 cylinder cars, so it just couldn't be adopted for our E60 535. Those who tried bricked their cars.
The other option is to have someone like Level 10 rebuild the valve body in the tranny and adjust the torque conversion dynamics. Big bucks involved.

Agreed...I run around on map 2 or 7.

Do post a log though...you would be a very rare exception if not the only one, that has good logs and isn't running meth to supplement fueling.

Aoschadlin ;

Your 2AAE code for lpfp, what was the 'fix' ?

Also are you up to running 100% e85 with just the inline fuel mod? How do you look at the logs and see if you can run more e85?

inquiring minds want to know

Hey

As of right now, I'm still getting the code. Under WOT or even general cruising.

I'm taking my car to another perf shop to let them have the car for 3 days to just fix it once and for all.

I'm currently running a range of blends during my testing. At the moment I have 100% 100oct in the car. Would be fun except the car goes into limp mode each time it hits 5k rpm.

I've noticed more fuel strain since putting on the RBs, which is perfectly understandable as they push a greater volume through.

Haven't had much luck with 100% e85, but hoping that will correct itself after my next shop visit, which is currently 8/7. *fingers crossed*

The easiest step at seeing if you can run more e85 is whether your fuel system handles it. Just log it and see if it's able to support the hpfp well enough. The finer details of AFRs and Trims etc, are a little more complex. I suggest run a slightly higher concentration, post the logs and we can all give feedback.

I'm also not completely sold that the inline pump alone will be able to support 100% e85 with RBs, so I'll probably help to mask that by running the 100% meth.

How do you know if you are over the limit (from the logs)?

Just that the trims are going above the chart?

Post some logs for people to comment on.

Default 45%E85 AFR High? - 10-11-2013, 08:19 PM

Just wondering what you guys think about the AFR on this log. Ive been getting the occasional limp mode error when going WOT in 3rd gear and when boost starts to build, I get a limp mode error and the car cuts throttle and upshifts for (thermal engine protection). Ive noticed that my logs where I have the error AFR is higher than normal logs with no issues.

that's a lot of timing advance you're running. And AFR seems a bit high to me even for race fuel.

Given all the information in this thread is mostly in reference to the N54, can all the same practices be applied to the N55?

That's a good question because I was just going to ask the same thing, since I'm running the N55. I greatly appreciate the feedback but I was wondering if the feedback on my log was based upon the N54 norms or the N55?
