Can someone with a BT tool and Cobb AP do us a favor:

Please, check your program reference reported by the BT tool with what Cobb AP detects and post it here!

Thanks in advance.

Ian knows what he's doing. He'll get you squared away.

nah, I actually found a solution to the timing drop issues for the most part

but now my car is doing some funny things in regards to boost and just feels overall slower then when I first installed the AP... same tune/conditions, butt dyno notices a huge difference though. And I doubt it's because I adjusted to the power since i'm talking 2-3 days and I felt something off

hmm now that you say that, i'm not sure if they reflashed mine, because I took mine in August for the HPFP recall and they kept the car over night to "update software". but I'm going to assume they reflashed it.

What was your solution?

well, assuming my theory is correct.... My car was so accustomed to the bad tune that was on it before, it adapted to having to constantly pull timing and so even with a new tune, my ECU would automatically pull timing around the same areas as before regardlessly.

Didn't know I could do this at all and never did it once since owning my car, but I hooked up the BT tool and Reset My ECU and adaptions such as: Air Control Adjustment, Knock Control (Which I think helped the most), Throttle Valve, Fuel/Air, Secondary Air Injection. And poof, the constant timing pulls in 3rd gear dissappeared.

Very interesting might need to get me a BT tool....

Is it weird that i might be having the same problem, coming from a tune that was running badly on my car?
Now on cobb if i run aggressive maps, whether S1 or S2, i get the same timing drop at exaclty 5800rpm. If i run the sport map i get the timing drop at 6200rpm, everytime on the same position. My logs look identical all the time.

Rob, does the "ECU reset" option on the AP resets the above stated parameters? or shall i just do it on the BT? Ive never seen a log of a timing drop at the exact same point everytime, or 4logs out of 5.

+1 would like to know, save me buying a BT cable.

have you ever reset your ECU at all since moving to the Cobb? i know some members do it between maps so I'm sure doing it between tunes should help overall

[vasillalov]

Come on guys... There has to be a lot of people here with Cobb tune, BT cable and a software update from BMW for the hpfp.

Can someone else please compare those numbers for us?

I've reset the ecu many times using Cobb hence why I asked rob the question, is it the same as doing each individually using the BT.
I will try it anyway.

I want to say no, because on the BT tool, they have a separate "Reset ECU" option and then different adaptions you can reset.

I will check, but I haven't had the hpfp replaced or any software updates well at least for the last 2years.

On the BMW AccessPORT, the "Clear Codes" option clears only codes from the ECU memory. The "Reset ECU" option resets all ECU learning/adaptations.

I just checked and what BT shows is different than the Cobb for sure, I'm on my phone can't remember what BT number was, but it's definitely different.

False alarm everyone!

I got some more information. Yes, COBB is absolutely correct! The BT Tool does not report the correct ECU program reference number. I managed to get INPA to communicate with my ECU and here is what I pulled out today:



I've sent an email to Bavarian Technic and I pulled a log for them to look at. Hopefully this will be resolved soon!

For the time being, until Bavarian Technic fix their software, ignore the program reference number reported by the BT Tool

[vasillalov]

I just received an email response from Bavarian Technic about this issue. They confirm it! Their software detects the wrong (earliest) ECU program reference. They will be sending me a test file and if it works well, this will be fixed in the next release of the BT Tool Software (hopefully):

Hello Vasil,

Thank you for the log file. We find that the program reference displayed by the BT tool is the earliest. This is the reason for the difference.


We might have a quick solution to this issue. We've made a small change to the file the tool uses to read this information from the MSD80/81 engine unit. If you would like to test the change to see if BT will display the correct information, let us know and we can send you this file for a quick test.

awesome!

I noticed you used INPA. I'll be doing some coding later and so was wondering how you got there?

Look into the Sneak Peak thread for Injector Coding. I posted a video.
