If you have excel, you can use my "Zasquatch Data Log Grapher".... I wrote a little excel program to do all the dirty work for you. Just a couple button clicks and you are good to go!

Perfectly normal to timing corrections when first pushing down the throttle, releasing the throttle, or under cruise and part throttle conditions. The car is trying to be ultra efficient for gas mileage and emissions purposes in these cases. Just monitor timing correction under full load.

Also, I've gained a few more Live Data variables, whats the "Gear" one show? I thought it might have shown what gear I was in but it doesn't seem to do that.

Is there a list that breaks down what all the live data variables show/mean? There are so many!
The BMW Tuning Guide will have a complete monitor list and description. The latest Beta firmware will not read vacuum, but the sensor provides more accurate boost pressure readings.

My car was feeling slow over the weekend, I'm probably just getting use to my mods and it's time for more I did a few pulls and the attached file is what I got. Running Stage 2+ Sport and everything seems to be okay. I do run 93 octane though but wanted to make sure all looks well before running the Aggressive map.

Anyone want to take a quick look to see if everything looks good or something I should be concerned about before changing? I just did plugs last weekend by the way before anyone says, "change your plugs"

logs attached. I did 6 logs and I couldn't get it to record from 2k - 7k rpm... it just did sections as seen below.

Yes it is the latest v1.6.5.0-3961 updated yesterday not sure about release date. How can you see that this is the latest does it look strange/different in some way?
What about those error lines are they have to be there?

if they are there than they are part of new logging channels in the beta firmware. those are logging channels. nothing to worry about .

Here are some more logs with something odd going on. In datalog #10 this was just after installing the wagner FMIC and changing to stg 1 +fmic agg 4.01. Iím still running 25% E85 and 93 octane and the ambient temps were 81*. I got a boost leak code at the very end of #10 pull. I cleared the code and did a few more pulls and some driving around. No more codes. On pull #13 a while later the boost is not reaching over 12? No codes and it drives fine. I did several pulls to try to heat soak the FMIC but that was the worst one as far as temps go. No boost leak codes though. Let me know what you think.

Thank you for the info. I will probably get to it tomorrow night.

Loving the cobb so far. I only wish the v4.01 drive ST throttle map was more smooth and a tad less boost. I noticed I get better highway MPG with the sport map 4.01 then with drive map 3.01. I want to be peaking boost low 13's and the drive map 3.01 seems to do it, but the 4.01 is a little hesitant and was hitting high 14's.

Still, its great to have options! And nice power and smoothness!

im lucky enough to have a cobb AP tuner locally. hes done all my tuning on my sti,which netted insane power. what kind of power could he squeeze out over the stock cobb tunes? would it be worth having him do a custom tune. im looking at FBO,RB turbos and meth.
im just super torn between the procede,JB4 and cobb now.

What is the throttle differences on the alternate versions on the maps on v3.01? Is one of them between stock and linear?

Rob Irish has stated that the OTS maps leave ~25hp on the table. If you're going from an OTS stage 2+ map to a custom meth tune you're probably looking at a delta of roughly 50hp.

They're for 6MT only. If you do have a 6sp, just give it a go.

Definitely worth it. You will be looking at some nice gains there.

So I went back over to Stage 1 v4.01 drive map, and it boosts too high. It boost like v3.01 sport. I like the lower boost levels of v3.01 drive map, but the way the v4.01 maps hold the throttle open on the highway work MUCH better for economy reasons (3-4mpg better).

Will cobb address this issue when the maps come out of beta? I have a log, will try to post later, of the drive map on v4 vs v3. I will have to figure those out. (its 2nd vs 3rd gear but still, 13.2psi max on v3 and 14's being held on v4, big difference)

With all the E85 talk lately (procede testing and now the JB4 E85 map), has anyone thought about getting an AP tuner to make them a map for an E85 mix?

Should I be hitting over 18psi on stg 1+ FMIC v4.01? I installed Wagner IC yesterday and ever since the car is way more responsive all around but the boost pressures worry me.

Anyone? 18psi seems high for stage 1 sport. Should I change to st1 aggressive non FMIC for now?

I believe 18psi is normal for stg 1+fmic. I hit around 15 with just stg1 aggresive.
