If worried about codes its always best to have some code management system like the BT Tool or CAN TOOL. The CAN TOOL is 80.00 with JB+ purchase so a great deal for a great tool.

The sensor is THERE?! awesome, N55 guys are very lucky

Wow. What a simple install compared to the n54. Sweet

[Busa1]

What's the difference between the JB+ quick install unit to the JB3 one? Is one better for a stock motor compared to the other one?

[henry418]

Wow, so easy to install. Hmm..

That was answered in the first post. Basically the jb3 has lagfix so better low end power.

Can someone post a dyno of jb3 stg1 vs jb+?

I don't think these exist yet, but you can compare the JB3 dynos posted to the JB+ ones I posted.

ok.... so I just installed the JB+... installation couldn't be easier. (even a caveman could do it)

I now have a aFe drop in, the JB+, a Vishnu cat-less dp and the Remus Race exhaust.

I have installed all of these parts in stages... so my butt dyno doesn't really feel a difference... am I missing something? The dyno says (above) says I should have gained approx 24 hp and approx 25 ft lbs or TQ. You should feel that .... right?

I am going to start a new thread with a video of a quick start and then a couple WOT runs...

@madman can you feel a difference with the jb+?

If you can't feel any gain with all those parts you may just need a new butt dyno. But if you have the CAN Tool you can plug it in to the OBDII port, use the boost on fuel gauge option, and ensure you're getting 12-13psi around 5000rpm in 3rd and 4th gear. If not you may have some issue or mod incompatibility going on.

hahahahaha ok... ya, I have a CAN Tool and I need to check that... I figured it would be plug/play I may call you guys in a few to make sure I do this right. Thanks!!!!!!

ok... vid posted

just a super quick sneak peak... I'm working with Terry on the boost... we'll see...

I need a dyno to be sure where I'm at with rwhp and tq... but with the JB+, and the Vishnu 3.5 catless and the Remus Race axle-back... I should be (around) 350 hp and 350 tq.... no? Does that seem right?

[madmanhiker]

Thanks to Terry I was able to see my boost on the fuel gauge via CAN tool hijack... but I don't know the exact psi. It looks like on WOT, the boost shoots up to just over the 1/2 tank mark and then goes back down when I let up. Now I see why people buy the separate boost gauge...

[PlatinumEdition]

does this work with the 2011 740i?

[Mike@N54Tuning.com]

BMS did around 315rw with the JB+ alone in 60 degree weather. I think 350rw would be about 20-30rw optimistic with Miami weather but can't hurt to find out!

BMS is taking their 135i out to the track tonight for some runs with the JB+ only on the car. They may also do some comparisons with the N55 JB4 Stage1. I would love to see a stock N55 run 12s with the $279 JB+ as its only mod.

Wow thats awesome so would 315rw be like around 390 Flywheel HP?

I think the conversion is around 1.13-1.15 or so on these cars, so like 360 crank HP or so.

is this still great news with the 2.40.1 DME firmware? My car is is currently on the assembly line and will have the latest firmware...

No, the JB+ gains aren't there with the new firmware. So you'll need the Stage1 which LOVES the new firmware.

Are they working on improving the jb+ for those who have the new software? The new software is much better for my completely stock 335. It now has much less lag off off the line.

No. They'll only be offering the Stage1 tuning.
