I ordered the car from Rallye out in LI too. If i went with JB+ I would probably leave it at the default setting. I just having a car that I have to worry about in case something blows up. Its like when I had the supercharger on the E46 I never really drove it that hard because i was afraid something would blow up. Didn't want to end up with a 10K bill from the mechanic or BMW.

Ha, i IM with him too pretty often. Hit me up in AIM (GBXSport) and we'll discuss. Been running JB3 for almost a year w/ no problems.

night and day compare to our sc'd e46's. Haha. And i can't beleive you never beat on yours. I drove mine like I stole it everyday w/ the asa blower!!

And dont waste your time...i know you...you'll want to upgrade to the JB3 as some point regardles...just get it now and enjoy it!

What is the expected whp and wtq with the JB+? Crank power?

Is it posted anywhere or confirmed what the JB+ actually does to gain power? Also for the BT scanner, do you have to use a laptop to read and clear codes?

How long should I wait before I jb the car mileage wise? After break in?

Thanks again everyone

Unless the road is twisty, you will always be a couple of lengths behind a car that is provided with JB3 and other mods such as better flowing exhaust system etc. There are others vehicles though if you want to be real fast and the performance difference between JB3 and JB+ is not huge. It also depends on your references, a few shaved 10s on the ¼ mile is a lot for those competing in the same segment. I’m also driving a tuned Suzuki Hayabusa -08 and the 335 will always be slow compared to this, whether it has JB+ or JB3.

JB+ changes the car to be much quicker than stock for a low cost. It also has a lot less circuits and connectors making it more fail-safe. Others may disagree, but it is the number of circuits, connectors and added software modules that defines the reliability, and JB+ works on a safer level power-wise. It does exactly the same function as the ECU is designed to handle, changes the TMAP sensor signal, as it would change with altitude. It basically fools the engine it is used at a higher altitude than it is, thus initiating more turbo pressure, about 5 PSI more than stock. The engine will of course not be as good to compensate for high altitudes as before since the roof is almost reached already on sea level if JB+ is used on max setting.

I think most people will feel a JB+ car is acceptably strong. 0-60 will be done in less than 5 seconds and the quarter mile may be propelled in 12's instead of 13's stock when conditions permit. I have come to the conclusion to stay with JB+ and enjoy the car as is instead of spending money to gain 10s of a seconds on WOT runs.

^^ left at default settings only

If your worried abt warranty just got with the JB+

JB+ dyno from Burger's website. Granted its not independent, but you'll get the idea. Def gains power....no ifs, ands or buts about it.


And, yes, you need a laptop for the BT scanner..its just the cable and sw you get.


DUDE, JUST GET THE JB3...YOU'LL REGRET NOT GETTING IT IF YOU GET THE JB+...MORE POWA....I'LL BET YOU YOUR BT SCANNER

i disagree. The JB3 is just as invisible is you run the proper map. Only reason for JB+ IMO is if you're on a budget.

I dont think a budget has anything to do with it. Most ppl who have it would probably agree that its because the ease of installation/removal.

[JayKay335i]

I just installed the jb+ yesterday and love it. The power over stock is pretty rediculous for a mod that only takes a couple minutes to install. I did it for ease of install and the amount of time I can take it out and put it back in. Overall I couldn't be more satisfied. Pick up a used one for under $180.

I pretty much got my JB+ for the ease of it. It's only been 3 days, but I'll admit, I already want to tune it up more or get a JB3. It's not that JB+ isn't good for power, it was just so easy to get that power that I want more easy powerups.

Can be difficult to install if you have big hands. I actually had another board member help me install JB+ and DCI so after we removed the air box, it was just plug and play.

You really can't go wrong with either one. JB+, PROcede, JB3, SSTT, you'll enjoy them all IMO. You might just want to get a JB+ and upgrade to JB3 later if the JB+ isn't enough.

Any issues at all with the JB+ so far?

Installed only on Saturday but no problems so far. I honestly expected a little more in terms of gains with the JB+ on day 1, but after 3 days, it seems to pull stronger than on day 1. Strangely I haven't been pushing my car much after install.

Anyone know what the top speed would be for an otherwise stock car with jb+?

[Craig@SupremePower]

Go with the JB3 Alan...

Torque seems lose during 2000~2500 RPM (compare to stock)...does that mean more lag?

[chiaobaby]

If money is not an issue just get the JB3 . A used one here is about 425 dollar range. Yes it is easy to install the jb+ but if you turn the boost past default settings it may throw a code? The JB3 has different maps available so far I have tried up to map 5 and checked with bt scanner and no codes. I think if you keep your car close to stock and just use jb3 on lower maps it should be ok . The first time install took me like an hour. then I uninstalled it to compare the gas mileage after 2 weeks. then the second install took 25 minutes.

Been running the jb+ at default setting for about one month. Easy install but, I do not feel the gain in hp/tq. as much as I thought I would. It may have something to do with the hot and humid conditions here in Atlanta. Looking forward to the fall and a dyno run. Overall, good product and customer service.

[1slow335]

I have had a JB+ on 100% for 3 months and it only threw a code ONCE!!!! My car is a 2009 LCI Sedan with probably the latest software. The difference between stock setting and 100% is ridiculous if you can run 94 octane or better. Kiss first gear bu-bye!

Already I have the itch to get a JB3. Anyone know what the car would feel like on JB3 Map 5 vs. JB+ at 100%? Worth it?

[Alan l.]

I would wish someone would just clarify what exactly is the JB+ unit is doing. How is the AFR's and what does cranking up the settings do. Its like a mystery box that just makes more power......I'd like to know how it accomplishes this.

Just means the runs were started later in the power band. Hard to match those up 100%.

check the dyno sheet jb+

C/P FROM BMS SITE
Q) What is the difference between the JB+ and the JB3?

A) The JB+ features a faster install and does not require you to touch the ECU. The JB3 is a more robust system including map switching, direct boost solenoid control, throttle position mapping, and many other additional features that allow it to produce a lot more power. On average the JB+ gives 40-50hp to the wheels, while the JB3 gives 70-80hp to the wheels, on an otherwise stock car.

C/P FROM POST #15
It does exactly the same function as the ECU is designed to handle, changes the TMAP sensor signal, as it would change with altitude. It basically fools the engine it is used at a higher altitude than it is, thus initiating more turbo pressure, about 5 PSI more than stock.

bOTTOM LINE IS if you will add additional mods to your car with jb3 it will adapt to your mods and give you more power then having a jb+?

It's not a particularly complicated device. It alters the TMAP signal as a function of boost, IAT, and time. This safely produces more boost, higher IPW, and less timing. All without the ECU knowing. The AFRs are the same as stock just like any other TMAP install tune.

Thanks^^

So why is that when you crank it above the default setting it could potentially trigger codes if all its doing is making the ecu think its running in high altitude? Isn't the ecu still doing what its designed to do if it was in high altitude?

What happens when a car already in high altitude installs the JB+?

Is the car also designed to increase boost if outside temp is extremely hot or decrease boost during winter?

I'm just trying to get all the facts together before I slap something on my car.

Thanks,
Alan

It really has nothing to do with altitude, that is more of an analogy. You will still see a boost increase at altitude, just less of an increase as that is how the JB+ is tuned. The hidden codes from from IPW going over a threshold that would not happen in an unmodified car. Sort of BMW's trick to find tunes. The JB3 goes about defeating this directly, but the JB+ or any tune without fuel pressure control simply has to stay under the limit or risk hidden codes.
