It appears this will be a FREE upgrade for S2 people.

Awesome. I'm ordering now.

[gclions]

Yeah, I've already got mine. I'm working shift work, and I hope there is a good discussion on how to set up the initial settings by the time I get off and I can get the changes made to the harness. This looks promising, and if nothing else the features will be awesome.

[MattPro]

I should be getting mine in tomorrow. I'll update here when I get it installed, have the day off so I'll have time to mess around. Going to order the BCM when it comes in, they should be up next week apparently.

Get to the Dyno asap would like to see independent results. I'm a previous jb4 fan too like to see Terry's tune for the n63.

[MattPro]

Got it installed today. Ran into one snag, but I got it worked out.

I haven't gotten a chance to give it any gas yet, I will mess around tomorrow on the highway and update with my results. But so far it is working and reading out everything in the JB4 log. Very happy!

[MattPro]

Did some testing tonight. Terry recommends staying in map 1 for now, but it seems to be a lot more tame then even the stock S2 settings. Under 5k I'm seeing 13psi and lower. It only spikes to 15psi above 6k which is pretty high. Asked for some clarification on what the map numbers mean for us N63 guys so we will see what happens.

Smart he upgraded the S2 guys for free as you guys will run into issues, hit him up, and he will find a way to fix them. Still, looks promising though. This thing is barely out of alpha.

TMAP sensor took a crap on me, still haven't gotten to push the car yet

How'd that happen? Just went bad?

Yeah, appears to be bad timing. The temperature part of charge air TMAP bank 2 is reading -44C, and the JB4 doesn't intercept it's signal (it does on the TMAP bank 1). So it really can only just be crappy timing. Dealer will have one in tomorrow.

I think that's why the car was feeling slow to me. So I stopped driving it hard until the new one comes in tomorrow. I'll update when I get it sorted, and then I'm filling up a tank of E30 and we'll see how she feels then.

[MattPro]

Got the new sensor in, what a PITA. That thing is hard to get to.

On 93 the tune is definitely more tame. Probably because it doesn't trick the DME into pulling timing by intercepting the charge air temp sensor. Boost levels seem low. But with E30 it is completely different. The car feels fast again, I can't get enough. My fuel economy has dropped so much but it has been well worth it. I'm getting a BCM soon and will update again after that.

I've put 600 miles on with the new tune since getting the sensor on, no issues.

[MattPro]

Got my BCM installed and setup. The car is wild now. I don't know its full potential yet either. The boost target right now is set at 19psi but I'm hitting the 20psi overboost protection since the Alpinas are a little more aggressive. I'm working with Terry to dial back my aggressiveness a little bit so I can keep it under 20. I'll try to get an acceleration video when I get it all worked out.

badblack550xi you got this new stuff from Terry too?

MattPro E30 is amazeballs!

[IBOOSTU]

where can i buy the new stage 2? and do i need to buy the stage 1 first then upgrade to stage 2 ? or can i just buy stage 2 and install it?

[mikekilpatrick]

I just got the JB4 with all the accessories yesterday. have to pull my P3 gauge as this new system has to take over your OBDII port. I am running Dinan Intake, Dinan inter-coolers and Dinan exhaust, so i am looking forward to working with BMS to get the most power and still retain daily driving. Love the Different mappings. Can turn it off, go on a 3000 mile trip, come back and go to the track.

I am also running a digital cluster so going to be interesting if there are issues over Analogue gauges.

Think i am going to take my Ipad Air 2 9.7 and mount it to the right of the NAV screen to monitor the Boost, etc as i will loose all that with P3 removed.

Anyone want to buy a P3 gauge mounted in AC vent already? lol

I don't know anything about piggyback tunes... I thought BMS already had a piggyback tune for the 550? How is the JB4 different?

i think the new Beta JB4 is an upgrade to their Stage 2 that they had, previously, for the N63.
