You should get an email soon, but I figured I'd go ahead and let you know you're ready.

Make sure you 'Check for beta firmware' checked in the options tab of AP Manager and then connect your AP to get the latest firmware with support for your rom. Make sure you get fw v. 1.6.7.0-5535 or newer.

Exclamation ROM Update Help?

Afternoon fellow n55ers. I am getting a lot of push back from the dealer regarding the rom update. I've cited all the information in the previous posts regarding rough start, poor acceleration, ect. Problem could not be duplicated, no codes stored. Denied. Taking it back again citing SIB120912 and complaining the problem persists. Any tricks or additional language I can use to insist they preform the update? My SA said that if they can't duplicate the issue BMW will not pay for any programming. I really would like to use the new AP sitting on my coffee table....Thanks guys.

All else fails tell them you want it done and will pay for it. $200 or so is what I had to pay before I could run my jb4.... I only have one dealership in my state.

All maps should already be in the firmware for you. If not, you are a 98F0B rom, so those maps will apply to you. If you have any questions on what map for your mods, that should be covered here:

Just got the car back from BMW on Friday. They had it for three days. I told them the following:

"I'm experiencing a rough cold start idle and when I'm in the garage I hear something that sounds very much like random misfire. More so, and most annoyingly, the car has this horrible habit of hesitating when I hit the gas pedal whether it is from a full stop or low speeds. It seems like it takes the car a minute to realize that I want to go faster, regardless of Drive, Drive Sport, or Manual Shift. I tried looking around online and I read that there is a possible timing issue that is corrected by a software update? Mind if I leave it here?"

The SA wrote everything down including my "quick research". He did say that it was very unlikely that it was a software issue because when you check your car in they get a sheet that prints out of any outstanding recalls on the car. Then I get a call saying that not only did they verify those problems but that my DME was throwing 9 different errors. The update fixed it all. Found this odd because for anyone who knows the car was in and out of the dealer for what they suspected was an engine problem just over a month ago, and you're telling me they didn't see any of the DME error when they were checking all the electronics and such then?

Anyways, car is back now and he is happy. Got the cobb aggressive tune back on him and going to install the AA FMIC this weekend.

Anyone know what the numbers are for a 335i and the following:

Stage 1 Aggressive
Stage 1+ Aggressive
Stage 2 Aggressive

I've only seen percentages but no indication as to which car...and one graph that had numbers but they were really low and I noticed the graph was for a 135.

We generally only show percentages as it should be relatively accurate regardless of dyno and car. We have a Mustang dyno in-house, so our numbers are usually a bit lower than a DynoJet. What you're really looking for is gain from your stock numbers... percentages are the best way we've found to set expectations without having dynos come into play.

Ah, ok. So looking at about 357max on the Stage 1+ aggressive depending on conditions and such. Not bad

Hey can you tell me which variables I need to log for this? I played with the AP a bit and checked / unchecked a bunch of stuff and I don't know what is what. Thanks.

Nevermind, I just reset the log stuff. I'll log some runs and send your way tomorrow. Thanks!

Josh,

In the link you posted can you tell me what the differences between Peak and Max are?

Max is the largest gain at any RPM
Peak is the gain at Peak RPM.

For example, say I have a stock car that makes 200whp peak and 220whp tuned. That's a 10% Peak gain. Now if that peak hp occurred at say 5000 rpm and the horsepower drops after that, then say I'm making 150whp stock at 6000 rpm. If tuned I'm making 190whp at 6000 rpm, then that would be a 26% Max gain (this is not a peak gain because we're not at the highest hp point on the curve).

The max gain shows the largest delta, but may not occur at peak power or torque. The main thing to look for in dyno charts (IMO) is area under the curve. Peak values mean very little in everyday driving.

Hope that makes sense.

Rough 1st to 2nd gear shifts

Just wanted to let you know that since I've had the tune which I lightly drove on at first and than got on it a bit but never past 4K. The car jerks pretty hard in D and DS from 1st to 2nd but in no other gear does it do that. Its pretty rough. I don't have any logs, but If you'd like I can take some under normal driving conditions or what is needed. Let me know.

Okay so i've had my AP since 23rd Dec '12. I've been waiting for my support for about 2 months because my car is Euro spec. Thats until Cobb decided to remove my support due to bugged software, thats when my problem started with the dealer. i've been trying to convince my dealer that my car needs DME upgrade since Cobb removed my current ROM support. 2 weeks ago i left my car at the dealer so they will make sure my car needs an upgrade. Sadly after 2 long days they called me and asked me to remove the DownPipe so that they can upgrade my DME. Today they had me talking to the Engineer in charge and he explained how i should put back the OEM DP so that the DME will accept a new ROM after the cat converter fault code clears out. Now im putting back my OEM DP tomorrow morning, leaving my car at the dealer next Saturday. Wish me luck :'(

Yes, that makes things more clear! Thanks for the explanation!

That's definitely weird. We don't change anything in the transmission, so its possible the car is still "learning" after the flash and reset of all modules. You can definitely send me some logs using the default monitor list. I'll make sure I don't see anything odd. Do a couple logs that cover what you're seeing, then also send me a couple logs of 3rd gear WOT pulls.

Hopefully they'll get you sorted. Once you're updated, let me know if you get an unsupported rom and I'll get it added asap.
