so here is my first datalog:

335xi, 93 octane, 90% stock settings. I followed the directions from the logging thread: 2nd gear at around 40mph, shift into 3rd and take it to about 110mph.

i'm too tired to actually adjust settings tonight and do more logging... but does this datalog tell anyone anything?

Was this run 1st, 2nd and a little bit of 3rd. gear? If so, you won't get much data from 1st. gear, 2nd gear is kinda ok but you are not getting the full boost; just my suggestion, trying doing 2nd and 3rd gear runs, start at around 2500 on second gear and take it all the way to redline in 3rd. gear, this way you'll have a more consistent boost level. Another run you could do is from 1st gear to 4th gear redline runs (well, as much rpm in 4th. gear before you run out of road at least).

I suspect it is quite cold currently. Nothing looks unsual provided it is cool out.

How long has this been adapting? It looks like a pretty fresh install to me. After mine adapted for a couple of weeks, I got a nice flat plateau on the boost curve in each gear, with boost tapering off about 2 pounds toward redline. Those boost graphs look kinda nasty to me.

If his location is correct, he is in a much cooler location than what you or I would see. PLus, a single pull for a limited RPM range doesn't show much. The optimal test if to run 3rd or 4th starting from about 2500 - 3000 RPM.

I followed the directions from the datalogging thread. I started in 2nd gear at about 40mph, floor it.. quickly shift to 3rd and run until nearly 110.

I installed this yesterday, so I would say it's a pretty fresh install

Drag your red line to the boost peak at the 6 or 7 sec mark. It looks like your at @ 14psi. You could probably bump to 92 or 94.

So, is your location CT or IL?

[jpsimon]

CT, it was probably around 15-20 last night?

at about the 12 second mark I'm at 14.4psi

14.4 is good, particularly in the cold weather.

I just installed this v2 last week and i was a bit comfused how this torque adjustment works. It was give to us at 90% settings, and were supposed to do long pulls from 1st to 4th at wot. Watch the boost correct? and make sure it doesnt exceed 15lbs. I have mine set at 94% right now cause it consistently gives me 14.5-15lbs boost in every gear. If i put 100 octane does that mean i can set it to 100%. Wont this pass 15lbs of boost, im a little confused, i use 93 octane if bring it to 96 octane can i raise to 96%. Any help would be appreciated.

[jpsimon]

So no real need to up the settings really eh?

I don't think you want to go that severe with a fresh install. Might want to run with someting current for 2 months before going to those extremes...! Theres a natural relation that takes place between the piggy and the ECU. It takes longer than most think before it's all working like a god!

Well i just wanted to know how it worked....i have not exceeded 94% across the board with 93 octane. Just curious how it would work for the future with using 100 octane and raising the torque numbers.

[turbojet3]

Raising the torque settings don't always raise boost. Some guys have bumped
from 90,92,94 and have not seen boost raise much if any. It might make the
timing more aggressive which needs higher octane. I would not go over the
14.5 psi regardless of which gas your using.

JP's log has his at 14.4 at 5000 rpms in 3rd gear and then tapering as it should.

Maybe He bumps to 92 it could be 14.5 or 14.6?
Keep in mind this log is in 20 degree weather. Warm weather it may read higher.

I say be happy with 14+

[jpsimon]

I'm gunna do some more pulls... 3rd gear from like 20mph till redline. etc... apparently i did this first log with the old software, i have the proper version now and will relog abunch

I think you're right. I'm at 14.2 in 20F and setting is at 94%. I'm going to leave it alone till the temp is up to 60 or so and do some more data logging.

[jpsimon]

I did some more datalogging: at 90% I wasn't seeing more than 12.3psi. I got up to 96% and was finally seeing 14.3 psi

Just need to be careful that when the weather warms up the turbos don't start working too hard and the psi starts peaking too much above 15psi
