Hey fellow 335i JB3 owners -

While my car feels fast, it isn't the holy crap feeling I had hoped for like everyone on here talks about.

Here's a little 2nd gear pull, does this seem a little slow to anyone else?

2009 335i E92 6 speed - JB3 Map 7 + BMS DCI
93 octane
73 degrees out, moderate humidity
1/2 tank of gas,
165lb driver
golf clubs in trunk
I've had the JB3+DCI installed for 2 months now. I don't have the DP's installed like my sig suggests

i dont see anything!?!?

[Jeff@TopGearSolutions]

Well, umm...

Your problem is map 7 and no other mods sir.

Try Map 5.

And try shifting at 6300 RPM. (and shut traction off all the way)

I am not sure what that video is suppose to proove?

This. The DME is probably pulling ridiculous timing to make up for you using a way-too-aggressive map.

I was told Map 7 is okay with intakes? I had been running map 5, map 7 definitely feels faster.

[mazdaspeed6]

its all depends on the car, 93 oct? seems normal for just jb3 and dci... can you do logs

[Sal@AUTOcouture]

Traction off completely and Map 5

[Forcefed3]

lolz you only went from 60 to 80... and your on map 7 with only DCI. Theres your problem.

[Clap135]

I would personally get rid of it and try the procede. With all the weather changes and various conditions, the procede will autotune everything for you. Or you can continue to scratch your head and wonder which map you should run or if the car is running ok.

[JhnR]

you really dont have to wonder which map is witch. its pretty simple if you read a little.

[BOOSTED4DR]

map 3 and 5 traction off, Map 7 is overkill considerin mods you have......

No actually you do. Because map 7 in my conditions is not the same map 7 in your conditions. There are poeple running 15-16 psi on map 8 and people running 15-16psi on map 5. The boost dances around based on what the stock ecu does. So in order to actually figure out what map is good, you have to log it, and then when you do, conditions and boost will changes and you just simply wasted your time.

The map quide, is just that, a general guide. Sort of like flash tunes, theres a general stage 1 stage 2 ect ect file that each car gets, some cars run concervative and some run aggressive on the same file. That is why anyone who is really concerned about getting power out of their car, starts logging and tuning themselves, or get it tuned by a professional. That however does not work to well with a jb3.

[luv135i]

lol at this post. There sure have been alot of Jb3 is slow posts popping up

[JhnR]

i keep it on map3 and works flawless and has tons of power over stock.

i would have gone with GIAC if there was no way of BMW knowing my car was flashed.

only thing i like with proceed is the "delete codes" feature, and i believe it has an AutoLaunch for A/T cars?

[Misturrtinnie]

Wow map 7 with just DCIs? Haha crazy. Pump some MS109 into it and you can be in map 7.

+1 to the lol at this post

[Bodie217]

Just went on a cruise on map 5, still feels the same as 7, but 7 had a bit more grunt

Then tried map 0, never doing that again

Thinking of going back to map 7 after catless DP's are installed

Thanks for the input all -

It's sort of hard to tell from a video. Throw it on a dyno, or do a few track runs, or some datalogs, to see how she's running. Map 7 is on the edge for tune only 93, you may be just as fast on map 5.
