So I ran today...a little disappointed. I wasn't able to datalog. forgot my laptop.

Conditions: 75 degrees, a bit humid (rained earlier)
93 octane, half a tank of gas, N55 X-Drive,
Mods: JB4 Map 2
JB intake
Vishnu catted downpipe
I ran in "S" mode with the Alpina software upgrade on my transmission the entire time.

Run 1: 13.8 @ 96 (1.85 60')
I ran map 2, peak boost was 15-16, 12-13 throughout powerband around 10 at redline :-/

Run 2: 13.7 @ 98
I reset to map 0 before run 2 and back to map 2, I trapped at 98! but still ran a 13.7 (1.9 60')

Run 3: 13.6 @ 97 (1.84 60')
Didn't touch my map but still disappointed with the MPH, doesn't feel strong up top??

Run 4: 15.0 @ 97 (2.1 60')
I was trying to get a crazy launch and my RPM's went above 3000 at the starting line and my car shifted to 3rd gear in "S" mode before i left the line, ran the entire track in 3rd gear. didn't shift until i passed the 1/4 mile mark.

I know there is a lot to process here, but I'd like to run e85 next time. Not sure what I have to do to get my traps up, or if there is something wrong with my engine? No codes are being thrown, the car pulls hard down low. 100 octane is a bit expensive. I'm not sure if map 5 would have been better but it seemed to be the same as map 2. Would a cobb be better? I know i need to datalog. which i will do tomorrow to record timing and boost.

/\ I dare say that something is not right.

My N52 powered car traps at 97mph. N55 with higher-than-stock boost and catless dps should be at least 105mph+.

Do some logs and see what boost you are making, which I am guessing is lower than it should be.

Will do some pulls tonight and Log. I eyeballed the boost, so that was my guesstimate. Should it be dropping to 10psi redline? Should i be shifting earlier?

I know it is not stock, i can see the difference when i run map 0 or map 1 and it hits 11 psi, and maybe 12 in map 1

Yea, something is def wrong.

Zero bolt ons with no tune run close to that or maybe better.

I had ran a 12.899 with Vishnu and AR dp only in a full weight e92 with no tranny flash on runflats and in 88-90 degree weather 2 years ago. I never ran full bolt on.

been talking with Terry at BMS, he can't seem to find anything wrong with my data logs yet. My boost spikes to 15 psi (map 2) then drops off steadily to 10psi redline. Take a look, first two pics are map 2, last 2 pics are map 5. did a ton of pulls tonight.

So I ran last night at Englishtown Raceway...

Temps around 72 degrees on the first run, 70 on the second run.
DA around 2000 i believe.
BA of 30

I have an N55 car to start off with, 2011 335i xDrive.

Mods, see sig, FBO + E40.
Weight: 3950 with me in it.

The first run was a mess, i didnt shift it and it redlined all gears :-/ timing was off, will post up my maps later

Second run i launched in 1st gear again, cut 1.76 60' although i know i can do better, i hear that i should launch from 2nd to avoid the 1-2 shift which wastes time. I shifted around 5500, car felt much better.

12.6 @ 108 was my best time last night,

I will post up my logs, as my timing was not >10 for the majority of my run, i was expecting to see timing at 12-13 degrees, not hanging around 7-8 degrees . Boost was good, peaked at 19 psi and tapered off to 15 around shifting point. I can make up more timing next time with a 100% e85 run, and perfect the launch. Any other suggestions?

Brett

edit: I tried launching from 2nd tonight, and the transmission either bogged, or i got a check engine light! Guess that's not going to fly

Yes, pulled the seats. But largest difference is running map 7 instead of 5, that is worth several 10ths. That is with stock runflat tires and stock midpipes with midcats as well. At full weight probably would be 12.25 or so.
