JB3 for 135i in JHB

[Baracus]

Hi All, just want to share the following (I'm a newbie to this forum and this is my first post, so forgive me if I accidentally trangress any forum protocol!):
Recently managed to get my hands on a late 2009 135i and am really exicted as I've just ordered the new JB3 v2.0 piggy back chip from BMS, thanks to Twinz & Revo! I know that other x35I owners have tried out the previous JB3 1.4 at Tarlton without much success, this was because the maps were only speced for sea level. BMS is based in California and holds most of the world 1/4 mile records for 135i/335i's. However what makes the new JB3 special is that v2.0 now allows BMS to custom tune specifically for my altitude and octane rating (BTW 95RON is only the equivalent of 90 or 91RM in the US :bawling. The problem with turbo's at altitude is that they work a hell of a lot harder and need the boost levels to taper off at higher RPM's. The combo I ordered comes with a BT scanner and a data logging R32 to USB cable which is pulled though to the cubby and then connected to a laptop. This allows for a whole host of parameters (boost levels etc) to be captured when driving and then mailed to BMS, who in turn mail back the appropriate settings to be inputted for altitude use. Chatted to Terry the owner of BMS is he is extremely confident that I'll acheive the performace numbers I'm looking for without much fuss. Expecting at least 40-50 kw gain. The nice thing about the JB3 is that its PnP, no cutting into the wiring or flashing the ECU. Furthermore once I've got the custom maps sorted I'll be able to change, while still in the drivers seat, between stock and othe race maps for higher octane as well. Also ordered the Dual Cone Intake to improve breathing. Will keep you posted on the outcome

That sounds awesome... please keep us updated.

Also have a 135i (at altitude) and am thinking of doing similar things so would love to know how it works out for you.

nice !:thumbsup:

not sure if it's true -BMW wants to can the turbo set up on the 335 engine -i'm guessing they the same as a 135- too much loss over warranty claims -2009 tax year for a specific model- this would take place in the new models :cursin:

i'm sure it's a plot :cursin:

guess all the boys with them engines are lucky -cause i doubt the newer versions will have the same brute.

As far as I'm aware the new N55 engine is definitely still comming with a single scroll turbo setup?

Baracus...i think we are connected in some way...Revo asked me to do a write up on the JB3 version 2.0 etc...infact i have written about it and my experience with it on another forum last month....and was about to copy-paste when i saw your thread...nice...:thumbsup: It will be great to see how the Juicebox performs at altitude...:thumbsup: In addition to the settings that Terry will send you...we will be able to custom tune your specific car once you have datalog the required WOT runs etc...its going to be awesome to see the result...i really hope it works out.

I will run my thread by this evening or early tomorrow morning:thumbsup:

Good to see you posting, Baracus.
Exciting times ahead to get the JB working well at altitude.
BS just need to get the DCI stock so that the order can ship... but I'll keep you updated :thumbsup:

Hi Baracus. As soon as you got your JB3 tuned correctly and are keen for a run let me know. I would be very interested to see a comparison of the good JB3 tune vs a flash tune.

 

[Dmonic1]

This sounds exactly what im looking for! being a PnP it will never be detectable by the agent! what are the costs involved here.
Twinz/Revo can you guys get the Injen CAI?

Hi Baracus. As soon as you got your JB3 tuned correctly and are keen for a run let me know. I would be very interested to see a comparison of the good JB3 tune vs a flash tune.

Good idea George...but the mods will have to be even out, in other words two stock 135s with just JB vs Flash tune....your car is a monster and it would not be a fair comparison to run against Baracus...

But knowing you as a very helpful person...a friendly run gainst Baracus; to see how far he can hold you off; would be interesting even though the odds will remain in your favour. :thumbsup::thumbsup:

But if baracus adds catless DPs in the future :thinker: my money would be on him... :thumbsup:

I am installing my stock cats for a service as well as the stock intake on the weekend so will be stock for a while. I can load a 1bar map to take the intercooler out of the equation.
The maps I have are probably not as refined as I would like but its nice to see the capability of the 2.0 especially when its correctly tuned for altitude because up to now the JB cars up here have a bad rep and its a shame considering they running 11secs state side.

 

[Twinz]

Thx George...your feedback will certainly help...hope this can happen soon. :thumbsup:

Have been looking into AR DP's but first want to get the JB3 sorted. Only just got the car, big adjustment from my modded GTI. Wanted to ask you how difficult/easy the DP's are to install and remove? Can I do it myself with some tools & a jack, or do you have to take into a xzorst shop? BTW what boost are you running with the intercooler at altitude?

The Dps can follow at a later stage, I pulled 292kw & 566Nm with stock cats and stock exhaust...so don't worry with this for now. We can ship you the DPs in one day from cape town when we come to that. The DP install is a challenge to do by yourself.

Twinz I'd be very happy with 292kw for now, was that on the wheels or calculated at fly? I assume that was with the new JB3 v2.0, what map and octane fuel were u running?

Baracus, if u need any help with the JB3 install just give me a shout
Although the plug n play one is childs play, I had to do the pin out version he he he

Many thanks Scouse :thumbsup:, would definitely appreciate some installation advice, looks like it can get quite complicated. The JB3 will probably only be arriving end of next week though. Could you perhaps PM me your number in the mean time, I know you had the previous version of the JB3 and wanted to ask you about it? Thanks

292Kw...was attained with the very old version JB3 1.3 on map 8. I had intercooler and racefuel (102 octane)...the rest of the car was stock. I wanted to see how far i could push the car on its complete stock exhaust and stock intake.

We then accomplished a similar figure on JB3 1.4 but on map 6...with the same mods above.

With JB3 2.0 we were running catless DPs; Intercooler;DCI and racefuel/meth...so map 4 took us to 301kw & 599Nm.
The important thing to remember is that these power outputs are delivered within the "safe" parameters of what the turbos can handle...
When you have the required supporting mods you can run less boost but gain higher power outputs...or run higher boost for even more power. But for most power hungry street purposes a max of 13psi is enough, when called upon.

The JB board can also be upgraded from 24ohm to 18ohm or even a stronger board (for purposes of meth and NOS) to enable the car to hold more boost but this will take you out of the safety parameters....for those brave enough we can modify your JB board to hold boost of 18psi, if you so desire...but it is not recommended unless you have a very specific goal in mind. I will update the JB 2.0 thread sometime to explain these options.

I only run my cars on:
Zeemax: www.hyperdyno.com
And the Bosch Services: Dynamometer
My outputs have been reasonably consistent on these considering other variables such as weather.

Well done Scouse, believe u ran a 13.4 1/4 mile stock standard today :thumbsup:

We are battling a couple of issues here at altitude and it's not something you can compensate for with other changes. The turbo's are running super-inefficient up here so you can't hit the boost target you want. Timing it totally dependent on the octane so you can't try to recover a few hp with some advance. Fuelling, I'm pretty sure all the tuners are running similar fuel curves. I don't think there's anything else the piggies control, that can make any significant difference to the way they run at altitude.

So the way I see it, you need to just graft away and find the optimum settings here. That might end up being 0.9 bar for a car with no hardware. But Terry will soldier on and I am sure he will get the car to run the best it can with the limited functions he can control. If anybody can do it, Terry can.
