That is 4 slots for REALTIME map switching, on the fly, selected on screen.

bc.1 = JB3 map 0
bc.2 = gas pedal selected map (put the gauge in this mode, and it will always remember what you had selected using the gas pedal jb3 method, so you can put whatever map you want into this slot)
bc.3 = JB3 map 3
bc.4 = JB3 map 7

When you hold the button down on the front face for 2 seconds, it will display your currently selected map, just tap to cycle between all 4, and then wait for 3 seconds and it will be selected. Super easy. You can check out some videos on my site under the install guides section.
Thank you sir I will definately be buying one soon!

thanks for the info

Then you have no idea what your speaking off...What other boost guage would not make it look ricey? I think its the best looking guage out there that doesn't make it ricey...I originally had a guage on the dash and thats ricey if anything, but I couldn't agree with you as for your accessment of the vent gauge, in fact I think you are the ONE and ONLY person that has ever stated something like that!

i don't think it's ricey, but tbh, I'd prefer one not in the vent because:
1) I like using the left vent to blow full AC
2) I'd like a non-digital one (just a matter of opinion)
3) yes, my car costs 62k, but for 400, I could get a set of DPs
But, if I liked the digital look, i would definitely get it heh
Maybe in the future

I was looking at STRI one since the gauge's color matches the rest of the car

No, I think it's in this order. bc.2 = gas pedal selected map (put the gauge in this mode, and it will always remember what you had selected using the gas pedal jb3 method, so you can put whatever map you want into this slot)
bc1= map 0

Also, typically, how much does it cost for a boast gauge install?

Thanks in advance.
I usually tell my customers thats its a good idea to have a gauge. With the JB3 you can get the Tuning Gauge or you can get Rix's vent gauge which is sweet, or there are a few other solutions out there.

Im happy with my $50 prosport premium gauge. Fits perfectly in the ashtray and is completely hidden. I would have liked to have bought one with map switching capabilities but thats too expensive for me right now.

dont get the STRI one, I've had that one too and its simply inaccurate and does not have peak recall

being in the ashtray i'm hoping it has a peak recall function?? There is no way your are driving aggressive and keeping your eye on the ashtray while also wathching the road.

Maybe its just me but I think having a quick moving gauge in the ashtray/shifter area is not ideal. Only gauges that dont move much (oil temp, oil pressure, water temp, voltage) should be in that location. Even a boost gauge with peak recall shoudlnt be there as peak numbers are not all you should be paying attention to on your boost gauge. You need to watch dips, boost spikes, bleeding boost, vac numbers off throttle, etc all the time to really help diagnose the health of your setup. You simply can not do that effectively and keep your eye safely on the road with a 400hp+ vehicle w/ a gauge that is by your knee.

my 2 cents.

Yup it has peak recall which is all I use it for. If I ever need serious diagnostic info, then I would hook up the laptop with the bt tool and run logs. I like having the gauge hidden from outside view and the dealership view.

if I'm not mistaken the JB+ wont log correctly like most piggybacks, thats why you need a good gauge. I'm referring to boost of course.

Same problem, you cannot use the BT tool to log boost with ANY piggyback, you will always just see stock boost.

Just to throw in my $0.02: I have the Rix gauge and love it. It's out of the way enough that you don't notice it unless you're looking. Install is easy, Rix's instructions are very comprehensive. Take a look through them and take it to a shop if you're not comfortable.

The air is directed at your hand, which isn't ideal in all situations, but it could be worse. I usually just leave the vent half open and it works for me.

I just leave mine in for service. I can't imagine they'd give you warranty trouble regarding a boost gauge. It's not going to mess with your engine. The guys at the dealership love it, some of the service guys asked if it was a BMW Perfomance option.
