Pretty coincidental me and my brother both got new cars within the same time period. I got 10' 335i and he got a 10' audi s4, but he pays about 100 dollars more a month than I do.

My question is: is the jb+ set at default and DCI enough for me to be faster than him ? I just ordered a jb+, and am very fond of the plug and play feature for such a small price (bought used on ebay for 150 shipped)

Hotrod got these #'s with jb+ using 91 octane
With JB+ 50F ambient temps

13.0 at 110.1 mph 2.1 60' 0-60 4.6 sec 0-100: 10.8 sec
13.0 at 110.3 mph 2.1 60' 0-60 4.6 sec 0-100: 10.8 sec 60-130:14.8sec

Stock: 55F (you can see the numbers are right on spec for a 335i)
(1st gear launches)
13.5 at 105.2 mph 2.1 60' 0-60 5.0 sec 0-100 12.3 sec
13.4 at 105.7 mph 2.0 60' 0-60 4.9 sec 0-100 12.1 sec

Should be enough. Is he auto or manual?
Let me know if you need some help My New E90 only has JB3 on it at the moment.

He's manual & im auto... and I am pretty sure a jb3 will easily take him. But would be awesome that a 150 dollar jb+ mod will triumph him and by the looks of those #s posted above looks like I have a strong solid chance since the s4 is about a 13.0 flat. Can't wait

Edmunds says the S4 does the 1/4mile in 13.2 @ 106.1mph, So the JB+ could have you ahead by 2 car-lengths and pulling away at 4 mph (if driven properly )

btw... what would be the "proper" way of racing from 20mph to say 80mph on a a steptronic. It seems if I am in the "manual" mode, and have it in 2nd and floor it, there is about a .5-1second period where nothing happens and the car just downshifts to 1st and goes from there. So on a 20mph run I would assume starting in 1st would be ideal to eliminate that "lag"

and from a dig to launch I would turn off the DSC, and just launch it say 2-2.5k rpms in DS mode for an ideal race ?

The JB+ is definitly very price worthy, but can not be compared to a real tune (Procede, JB3 or GIAC) regarding smootness, response and power.

I had a JB+ and found myself wanting more.. you till too..

Pretty curious if I will, saw some vids of jb+ keeping up or passing e39 m5s.

Drove and road in that car plenty of times and that thing is insanely fast, I can't see how I will want more, but who knows....

I said the same thing as you... watched all of the vids... other people's claims... etc.. and I still ended up with a JB3...

The JB+ is a great tune for power, price, and I had it for about 15k miles... but when JB3 2.0 came out I bought one.. and I am so glad I did.. the JB3 and JB+ is night and day...

You will find the JB+ falls flat on it's face on the top end compared to JB3.. from a dig the JB+ pulls hard!

Yea... i probably see myself getting the jb3 after, but It's nice that you kept the jb+ for 15k miles- must have held down your mod hunger for quite a bit. I would probably want more after the jb3, so I don't want to just jump right into it first.

[htoudiee]

I can tell you about a GIAC S1 that I pulled on a 2010 S4 in a 45 to 130 by about 3 cars. JB+ should not have a problem. Just try not to go from a stop I'd say.

+1, i had JB+ for about 6000 miles, then couldn't hold any longer and bite the bullet of JB3. JB+ gives you the feel of a single turbo engine, either it doesn't pull at low rpm or power just comes in ~3k rpm and flat out ~5k rpm or after.

JB3 runs a lot more smoother and very stock feel, less power jerk and 5k rpm after, power keeps coming in. also if you are planning on getting exhaust, i notice JB3 will quiet down the exhaust a bit which i like.

i tried to put a full tank of 100 oct when i had JB+ @75%, it sure felt better but there's only as much JB+ can give you if you are running higher octane. after JB3 in map 3, a full tank of 100 oct, which is day and night compare with JB+ @75%.

OP can try out the JB+ for a few months first, until to a point you need more within the 6 months period, you can always upgrade to JB3 from BMS

What setting was hotrod on? 75%? or 100%

Sounds about right, unfortunately I won't be to get the upgrade from BMS since I bought a used unit on ebay, but it came out to 169.99- (8% live discount of 13.52) so not bad, and I could always sell it for about the same price once I am done.

Thanks for all the advice support guys!

[Mr. 5]

It's never enough.

[PhiDeltBeers]

Even on map 3. Still not enough, but fun.

[Bagelfast]

Do a 40mph roll. keep it second manual mode.. Dont heat soak or floor the car prior to racing so the car is cool. But you want the oil temps to be around 180*F or higher so you have full performance.

Let me know when its going down, i would love to see it, ill even give you a hand installing it.

haha... sick your in brooklyn. I should get the jb+ on thursday, so friday would be a good day to have it installed. Some help would be really appreciated, reading about the install process I see its pretty hard to find that TMAP.

Once the car adapts to the jb+, me and him are gonna have some little fun races =]

[finesta101]

With a JB + you might have a chance to take him on a roll but highly doubt that you'll stack up to him off a dig and make sure by the time you get your chip he doesnt get the MTM which is giving him 430 whp

[chiaobaby]

Once you go a taste of more HP you will want more just Get a JB3 first then you wont say to yourself I should of got a JB3 in the beginning.
