N55 cars haven't been out as long and certainly don't have the same R&D time behind them as N54s, so it's understandable if the jury is still out and might take some time. But the whole testing and tuning and logging ordeal doesn't have me intrigued.

The 435i will be my beater and starting next year, my M-F work commute will be <5 miles round-trip. I'll mod it, but I'm not going to mess with worrying about messing with the tune and be the dweeb driving around with a laptop in the car logging. With E85 available locally, it would be nice to just mix 50/50 with 91 and enjoy the extra power.

Diagnostic values for N54 and N55 are the same, we are still looking at temps, timing, boost, targets, etc. However the N54 is able to handle more aggressive settings due to the broader DME access. N55 is more restrictive since it's a different DME platform.
Also the engines are identical except N54 is twin turbo, N55 is single twin scroll.

I was thinking about the timing parameters and AFR specifically. So you're saying the target values are the same then?

I'm sure this is a stupid question but, does it matter while mixing if you put e85 first then 93?

Personally I've always put the e85 in first to allow the 93 to mix it all up. Been doing it for about a year now?

No scientific basis for this of course.


Cool stuff no longer installed.

I do E85 first so I can put in the right amount of gallons. Then I can just top off with 93.

Thought so.

Guess the only thing I've been doing wrong is every other tank filling up on 100% 93 just to clean out the e85.

With an E85 test tube, mix e30, add to an empty as possible fuel tank, do a few runs to help the car adapt, log and post in the support section.

From there you will need the E85 Flash and stage 2 LPFP, but post the logs as mentioned above and guys will assist you from there.

Hey everyone. I've got a 2011 335is with a 7 speed DCT. Only mod other than the JB4 is a Cobb drop in filter and a Cobb charge pipe.

Can you guys look at my logs and give me your opinions please?

5 Gallons of E85 mixed with 93 octane. Temp is 59F. High humidity if that matters...

The first number of pulls are right after the fill up and are to calibrate map 5. The last few should be pretty representative. Please let me know how it looks and if I can go another gallon or two.

I've put the log file on Google drive, hopefully you can see it.

Thanks for your help!

you really need to post in the right section - Support section. Also include csv logs in post if possible.

Here: http://www.n54tech.com/forums/forumdisplay.php?f=35

Upload your CSV to datazap or similar log hosting/chart service.

Create your own thread there, don't hijack another. Also usually not good practice to revive a dead/old thread unless it's a follow-up to the original.

Good luck.
