He's got corrections in every single cylinder? And multiple corrections in most of them. IIRC, only one cylinder had just one correction during the pull.

Hmmm Actually no. Probably not a bad idea! I usually drive it around for a bit - hard but no WOT runs.. And then log it..

I'll do a few WOT pulls and then log. Watch this space!

Thanks!

Thanks. Any FMIC you could recommend? I talked to the service manager at dealership yesterday and he said don't worry about getting Dinan. A FMIC shouldn't void my warranty.
You might already know this but just incase you dont. Dinan parts can still void your BMW factory warranty. You are supposed to be covered by a Dinan warranty but your factory BMW warranty can still be voided even with Dinan parts. With that said I haven't heard of one person on here having warranty issues over an upgraded FMIC.

It all depends, I wouldn't walk confidently into a dealership with an upgraded FMIC...
You never know the SA you're going to get. The first one I went to when I got to Atlanta and still had warranty was an unenthusiastic, unpleasant person who I am sure would try to screw me if I had a FMIC.

Wanted to update everyone on this. I have been Cobb Stage 0 map for about 2 weeks now. The lean code is not coming back, but when the car sits for 8 hours then you crank it, you hear a bit of a stumble. This is very indicate of fuel injector leaking. Last time I had to wait till I got the check engine code... wondering if I can get it reviewed prior.

I don't like all the timing pulls, but it seems worse at light load sometimes than WOT so it's not as scary as thought when I first started scanning. What fuel are you running? I would back down to Sport if it was me, or start using ATR to make a custom timing map. I wouldn't run it on a road course that way, but it's probably not going to hurt anything on the street with just a few seconds of WOT here and there.

I’ll look at that log when I’m home from work…but just putzing around town the DME uses timing corrections and ignition advance/retard as a normal part of its logic. There is nothing remotely odd or wrong if you are seeing timing corrections under partial throttle. It’s under WOT that you want to see things settle down.

I have a couple of questions before I buy one of these and I don't have time to view all 380 pages. (Already looked through the FAQ's)

1) What is the difference between the v2 and v3? Just touch screen? I can still use any maps on v2?
2) Do they have a quick way to reset it back to stock without unmarrying it (if I want to take it to the dealer to get it checked out)
3) If I have catless downpipes will it clear the o2 sensor codes (like JB4 auto clear?)
4) Is Accessport now available for my tuner?
5) Do they have the ability to add multiple maps? How many? Switch on the go? (it just says it takes minutes)
6) What is the best map for DCI, DPs, Charge Pipe/FOrge DV's, and FMIC?
7) Is there a special map I need to use or any extra things I will need to use E85? Or can I just fill up with E85 and set it to my FBO map?
8) Does this work with MAC OSX? or If anything will it work fine in Parallels?

Thanks guys.

I know I can tune it out. Why would I want to let it do that as part of normal operation? I still want to know what fuel he's running, because I don't think it's good enough for that timing table.

1) What is the difference between the v2 and v3? Just touch screen? I can still use any maps on v2?V3 allows for multiple gauges to be displayed at once and a little larger than the v2
2) Do they have a quick way to reset it back to stock without unmarrying it (if I want to take it to the dealer to get it checked out)There is a stage 0 map that sets it back to a stock mapping but the cobb is still married, if the dealer updates the ecu or anything you will probably have a problem if it erases the tune
3) If I have catless downpipes will it clear the o2 sensor codes (like JB4 auto clear?)Any stage 2 map will auto clear
4) Is Accessport now available for my tuner?A tuner can buy the ATP tuning software or you can use ATR
5) Do they have the ability to add multiple maps? How many? Switch on the go? (it just says it takes minutes)The AP can hold a good amount of maps, mine has like 9 maps on it but i only use two. You can switch but not while driving or anything. You will have to pull over and turn the car off to switch maps.
6) What is the best map for DCI, DPs, Charge Pipe/FOrge DV's, and FMIC?Stage 2+ is created for those mods or you can try any of the race maps.
7) Is there a special map I need to use or any extra things I will need to use E85? Or can I just fill up with E85 and set it to my FBO map?Cobb has a beta race e30 map that you can use just make sure to log and make adjustments if needed.
8) Does this work with MAC OSX? or If anything will it work fine in Parallels?Not sure myself but haven't heard of any problems using either.

Thanks guys.

Ya going back to Sport, I think GAS octane rating is BS here in Chicago. Anyway that was on 93 Octane, I have full bolt ons. Scheduled PRO Dyno tune at P and L Motorsports anyone knows their reputation for tuning?

P & L in franklin park? I know they did a really nice job on a PRO tune on my buddies 2010 WRX. From what I've been told they do really quality work. I personally didn't know they even did bmw until a few days ago. I was going to go with an e-tune from PTF, but now you have me thinking of making the trip from plainfield to P & L. Keep me posted on how it goes!

Yep Franklin Park IL. I don't want someone that is not qualified to work on this. They told me they will fly some guy by nick name of Junior to do the tune on many cars. I rather pay couple hundred more then pay like 5K for a 2nd hand engine if they blow. Got their address right off COBBs web site so I hope they are good. I have seen cars blow up on dyno lately and after that I changed my mind and went with P and L. I let you know after 11th of Nov.

Anyway I really need to learn how to do this tuning my self but not on my car LOL.

First p29e0, then p29e1 (fuel mixture) and then eventually p0171 (lean condition). Typically when cold, less frequently when warm, but every day now. Once the third p0171 occurs then the SES light comes on. All clear fine but it repeats. Here are two logs:

http://www.datazap.me/u/jeffman/e10-...ottle-diagnose

Does anybody have any idea what could be causing these codes?

Sorry to bring up an old thread, but Im having the exact same problem. I was running the OTS Cobb E30 map and calculated wrong ending up with an E34. Car ran great I happened to check for codes and got 29E0 fuel mixture control,
29E1 fuel mixture control 2, and P2AAF fuel pumpe, plausibility. The car did kick a SES light at one point but no limp mode. I was running low on fuel so I cleared the codes and filled up with a quarter tank left with shell 91 and switched maps back to Stage 2 +. The P2AAAF code never came back but the 29E0 and 29E1 keep returning even after the 2nd full tank of 91. I do have UR catted downpipes which never threw a code after I installed them on the car stock before I got a tune. A buddy of mine said the E85 could have killed the cats which is why I'm getting the codes now. Ive read these are the codes you get when you go with cat-less downpipes. The car runs and pulls great LPFP is in range not sure what else to check. If this is a cat-less down pipe code I'm gonna ditch these UR catted down pipes and just go cat-less.

I have I8A0S . Ive been running the cob for about 6 months with no codes until about 3 weeks of running the E30 maps then the P2AAF, P29E0, and P29E1 started showing up. now that Im back running 91 with stage 2+ ST I'm just getting the P29E0, and P29E1 codes

I'd just keep an eye on it. If your trims and afrs are fine then I think it's just the dme reacting to a fuel mixture it was never intended for
