Use steering wheel controls. Set it to 5-1 to calibrate for the 135 gauges.

I still need advice on which flash do I use for my car. I have a 09/2012 built 335i e92. Do I use the DME unlock version or the other based on that MHD you no longer need to do a bench flash? Also I have a DCT is there a file for this transmission or does this no apply? Thanks guys

You want the 9E06 files. Bench unlock is no longer needed. iOS software just came out about a week ago so no Android device needed if you are an iPhone user. You will need the orange MHD WiFi adapter. Terry/BMS sells those.

I have a 6MT so can’t help with DCT other than to tell you that there is software to be uploaded for that.

Should be a very simple search

Please search. Knowledge will help you much in the tuning game.

You will need XHP software for the the DCT.

This is from post 1 of this thread:

Use Guide:

To load the flash first set the JB4 to map0 disabling it's CANbus. After loading remove the android device, select mode 4/2 in dash so your JB4 knows you're running a BEF, and then select your normal JB4 map. No other JB4 settings needed. NEVER select 3.5bar TMAP in MHD when flashing even if equipped with a 3.5bar TMAP sensor as the JB4 is already programmed to do that conversion.

PUMP: Suggested for most applications ranging from 91/93 octane up to E85 mixtures of around 40%.
E85: Suggested for E85 mixtures of 40% or more.
E85_PI: Suggested for E85 mixtures of 50% or more with the use of methanol injection or port injection.
E85_PI_ST: Same as above but optimized for larger single turbo use.
THR: Factory throttle mapping, some cars running xHP trans software have reported smoother performance with factory throttle maps.

I see that in the first post there is new information, "Once installed and the JB4 is set to BEF mode (option 4/2 in dash) the boost targets on each map will change to higher boost absolute maps designed specifically for use with BEF maps. For example map1 goes up to 16psi peak, and map2 goes up to 19si peak. " Wasn't that when we have an n20 tmap sensor?

I am confused on which backend flash file to use. I have Dual Clutch Transmission 135i with the n55. do I use a file from the newest release on 10/3/19? or from the previous batch of files. I see and special dct file in the newest release but its a pump flash. I am running stage 2 lpfp with a E60 blend of e85 and 91. the car is 2011. Thanks for helping!
