We provide tuning support to race teams around the Globe including the USA, Germany, Australia and have tuned everything from street/strip/road course setups on stock turbos to big single/twin conversions to winning 12-hour race events such as the Bathurst race in Australia. Our approach is based on years of tuning experience on and off the dyno and we're a certified Cobb protuner shop and a dealer.

In terms of load by gear, you cannot do boost/load by gear on the Cobb right now. Its being tested on MHD and to our knowledge it isn't confirmed yet to work 100% but we could be wrong.

Let us know if any other questions at all.

Thanks for the reply PTF.
Will you all support the MHD app / tune through that app for android? I'm really hoping to not pick up a JB4 and stick with cobb. I just hope us cobb owners can get boost by gear soon.

Basically, I see no benefit of going full boost in 1st or 2nd as it will translate to wheel spin even with LSD.
Sorry if that's a newb question.

There is a way to limit power output on the onset of WOT for drag racing if this is the intended use. There is no specific gear by boost unless you have a newer N54 and that itself is limited

On the MHD development they do or will have where you can set different load targets ie boost by gear

The JB4 make it a lot simplified yes, but not exclusive for the goal you want to achieve if we are talking about drag racing.

Btw, Wedge - Ken is WedgePerformance, BuraQ - Dimitri is BQ Tuning . Its still all WedgePerformance .

Understood. Thank you both for your kind replies as I learn this new (to me) platform.

I have a ques i have a stock 2011 335is i recently installed the stage 1 aggressive map. The other night i had an extremely rough idle turned the car off and restarted and it went away. Then it happen the next night and same thing happen. I pulled the codes and i had a misfire in cylinder 1 and cylinder 2. My car is still covered under CPO warranty if i reinstall the stock map will the 2 codes still be in the ECU or they get wiped clean when i reinstall the stock map??

Wiped clean

Getting the following:
P0303 cyl 3 misfire
P29CF cyl 3
P2EFF electric fans self diagnosis
P2AAF Fuel pump plausibility

Lasts a day or two, and before I can take it to my dealership, they clear themselves. Is this common for Cobb to clear these codes automatically?

This has been happening for months. And the engine runs like a champ with or without the codes.

Can I please ask for help from Cobb Tuning or someone to review my logs and tell me if logs are normal?

It looks like I have a decent amount of timing corrections on the E30 Map and I'm not hitting the boost target.
I can't tell if I have a fueling issue, I hope I recorded the proper measurements?

I have a 135i manual with FBOs, I was running 4 gallons of E85 with the rest 91 octane.
I did 2 runs on the standard Cobb E30 map and one on the aggressive map.

Thank you for the help, I'm new to logging.

MHD Tuning Is there any ETA on boost by gear? To aid in traction, etc...

Still don't understand why these codes are clearing themselves after a day or two.

Need help guys, I think I TIFU'd.

My car went into the stealership for injector replacement, and, silly me, I didn't uninstall my AP prior to this, but had flashed back to Stg0. While there, they updated the BMW programming as well. This morning, I went to put the AP back on the car and proceeded to flash to the Aggressive Stg 1, which felt extremely sluggish pulling out of my driveway, so I stopped and reflashed Stg0. It now occurs to me that I have no idea if the maps are related to the software it finds in the ECU (i.e. i was on IJE0S), and now that it has been reprogrammed, I might be flashing bad maps into it, or if it is based on the hardware in the car (in which case, my car is always going to be IJE0S); can anyone clear this up?

Since I didn't uninstall and reinstall it, I also assume that uninstalling it now will flash back the ECU programming from when I originally put the AP on my car, not what it recently recieved in the dealer; is that also correct?

Really hoping I didn't ef things up too bad. and thanks in advance for your help!

I guess the question is: Is the coding for the injectors lost? My guess is yes. Why where the injectors replaced?

COBB Tuning I'm brand new to tuning and trying to understand the different maps. I just received Cobb V2, and I'm completely stock with access to nothing higher than 91 octane. It seems the Stage1 Sport is most appropriate for me, but the documentation doesn't seem to align with the massive list of maps.
For example I see:
IA80S Stage 1 Performance
IF80S Stage 1 Performance
IGD0S Stage 1 Performance

Is Performance the same as 'sport'? And Race the same as 'aggressive'?

What's the difference between all of the map IDs?
Thanks

Those all refer to different ROM's. You need to find which ROM your car has and then load the appropriate map.

Can my ROM be found from the Vin? How do I know what version I have? Sorry, brand new to tuning

[Rezinator]

Plug the Cobb AP into the OBD port via cable. It should tell you which ROM you have and will only allow you to download maps for your vehicle.

Easy enough, thanks!

[Flex68]

I'm looking At buying a access port v2 .... Any major difference between the v2 and v3 ???

Would Installing a Cobb erase my coding done to my vehicle ?

Awesome thanks for replying saved me starting new thread

Sure it's been asked. Switching from jb4 to Cobb. With jb4 it didn't "activate" until you were over 160 degrees (or something like that) for safety reasons, is this the same with Cobb? Or is it "on" all the time?
