Also, your mid range boost is really low. All of which can be fixed.

What do you think needs to be fixed exactly? I brought it to try and get new turbos/wastegates, but dealership said it was all within spec. Carbon cleaning, and spark plugs were just done. I replaced 2 coils due to misfires at same time as plugs, but right now am not having any definite misfires compared to when I knew I had them. Just a general lag feel overall.

Thanks for all the help.

Short of doing a custom tune for your car, I would change OTS maps and see if one of the other OTS maps works better for your car.

Anyone know turn around time to unlock v2 to v3 maps? Was going to go to track tomorrow and use my PTF RB E30 map, Unfortunately can only use the OTS maps

Is there a specific thread where people share tuning insight with Cobb's Accesstuner Race software? I wouldn't mind checking out some custom tunes for these cars.

Google seach: "howto - cobb atr discussions, maps"

Theres a lot of reading, however mostly everything there is theory and elementary.

You will have to understand global PID tuning but will still need some advancing when being applied to our platform.

A more "fundamental understanding" of PID on the N54 comes from experience and dumping $500 - $1000 in gas to learn how it and the N54 DME logic works.

Here is a sample of some PID tuning and Overboost being enabled on the 335is which required a complete overhaul of PID when Overboost is enabled. Another reason why ProTuners dont mess with it cause its a hastle to dial things in properly

Hey guys, made my first log (but screwed it somehow).
However, what do you think?

cyl 5 timing looks screwy

Load is overshooting req load, and you have a serious issue with cyl 5

What could be the reason for cyl 5?

Cyl 5 is problematic for a lot of people even after ruling out the usual suspects, good thread on it over on BB (won't let me post link sorry)

Thread is titled "CAN WE GET TO THE BOTTOM OF CYLINDER 5 TIMING?"

Do these logs point to injector failure? It seems like it based on the smell of gas on startup, sluggishness, hitting boost and load, and I have no other idea.

When I run the ots e30 map, I feel like the traction control doesn't interfere as much as on stage 2+. I normally drive with a single press of the tc button, not off completely.

Does the e30 map reprogram the traction control?

Humann · 10-11-2014, 11:53 PM

Just throwing my problem out there..

Have stock downpipes on and everything is running perfect with stage 1

Put catless downpipes on and now im getting misfire codes and its spuddering and it tries to die at idle sometimes - stage 2

=C= · 10-12-2014, 01:09 AM

When flashing the ecu with cobb v3 on my 335i I noticed what sounded like a fuel pump constantly running. Is this normal? The flash lasted for 3 to 5 mins. Battery flat warning light came on afterwards. ..

Normal, and evertime you flash a map you will hear the pump running. Nothing to be alarmed about.

For the battery warning to come then you must be have a dieing battery to do that within 3-5 minutes

There is a table that you can adjust the sensitivity of TC, but thats a Protuning option thats not going to giving out freely

Reset the ECU using the Ap, thats a major mod change for the DME

Just to add on to that. Should I be using the Stage 2 Aggressive ST or LT?
