See below. Hopefully this helps everyone:

Stage1: Connection to both TMAP sensors only. This allows performance equivalent to the current Stage1 system for someone looking for a quick and simple install.
Stage2: Adds in OBDII CANbus cable providing in dash map changing, boost gauge, boost by gear, stronger and smoother mapping, etc.
Stage3: Adds in two pairs of wires to the DME for fueling support allowing the use of E85 fuel mixtures.
Stage3+BCM: Adds in a BCM module that connects to two additional pairs of wires in the DME for direct wastegate control. With sufficient octane this allows the system to fully maximize power.


n63 JB4 MAP GUIDE:

Map 0: JB4 disabled
Map 1: 4psi over stock additive
Map 2: 6psi over stock additive
Map 3: Undefined
Map 4: Stock map w/ CANbus enabled
Map 5: Undefined
Map 6: User defigned boost additive map. Enter boost over stock values to use. Requires experienced tuner.
Map 7: 8psi over stock additive, requires BCM
Map 8: Undefined

Firmware Updates:


Current dash settings as of OBDII v1 firmware:

'***************************************
'OBDII In Dash Menu
'***************************************

'0 map menu, map shown on tach (TACH shows Map)
'1 Unused
'2 Boost gauge on fuel, scaling in dash is 0 to boost safety setting, turns on when gas pedal is pressed 50% or more and turns itself off when you resume low throttle use. (OFF tach = 0, ON tach = 1000)
'3 Unused
'4 Delete fault codes.
'5 1st gear boost limiter. (Tach = boost cap / 3)
'6 2nd gear boost limiter. (Tach = boost cap / 3)
'7 3rd gear boost limiter. (Tach = boost cap / 3)

Do you have a link that image?


Is there a noticeable difference in Map 2 With and Without the BCM on just a tune only F10 N63?

I do but I deleted it to keep the confusion down.
