Probably not the best suggestion until next summer depending on where you live, but you can blast the AC during the last 5 minutes of your drive to get the water temps back down to 90-95C to cool everything down before shutdown. I do this and still hear the aux water pump whirring away after I park but the fan no longer comes on.

 

Why would this not be a good suggestion? The car is still going to be hot even if it's cold outside, I would think letting it idle down for a minute would just let the oil continue to circulate while the turbo cools off for a bit.

;-) blasting that ac when its 3° out just gets a bit cold in the cabin

 

Hey, up to you It's what i do but it's 80 degrees outside.

 

It's not 80° here right now, but it's been in the 40's and 50's mainly during the day, with the occasional 60° day like today the last month or so.

How does this look guys?

94 octane gas
70% on the dial



Can i bump her up?

 

I have used toluene as a booster in my R56 JCW racecar for several years. Also have used mmt, and recently have been trying 20% E85. I have also run 102 RON racefuel.

I run toluene at 15% by volume, but you can run up to 20%. This gives a strong anti detonation benefit. Also the burn is slightly slower. The antiknock effect is similar to running a percentage of E85. The cooling effect is not as pronounced as E85.

Running 15% toluene (or 20% E85) allows a safety margin with a stock tune under extreme conditions eg racing under prolonged high load, high boost high temp conditions. If you wish it will allow you to crank up the boost a little higher.

I would use toluene or E85, whichever is easier to get your hands on in your local area.

 

I'm sure this has already been covered, but I got lazy and was hoping for a quick answer:

I just threw a CEL light (according to the manual it corresponds to an emissions error or what not), after having the JB+ in for about 150-200 miles. I'm still waiting for my CAN tool (non-BMS) to show up in the mail as I left it at my exe's house, so I haven't cleared it or pulled the code yet. Anyway, I'm assuming this is due to the JB+ as all other things are equal. Am I correct in my thinking, or should I be on the hunt for something else? I have no other modifications on the car, so it's all stock minus the aforementioned.

Also, I'm going to have it read and cleared today I just wanted a lazy mans answer lol.

DHfreak, there is honestly no way to tell if the JB+ caused it without knowing what the code is.....

i suppose you can remove the JB+ and see if the CEL goes away.

 

Yeah I knew that.....I was just wondering if anyone had any off the top ideas. No worries, I'm heading out to have it read now.

 

one possible way to tell is take the JB+ off, clear the code, and see if it comes back. also, if you get a chance, open up the JB+ and see if it's a green or brown circuit board inside. if it's brown, drop terry a line. i highly doubt it'll be brown, but you never know. nothing to be alarmed about, but during beta testing, the brown circuit boards threw error code 277A.

 

Read the code and if you need tech support just email it in.

 

I just now found out that JB stands for 'juice box'. That's a pretty cool name and an apt descriptor for a tiny tune packing serious punch.

 

I'm glad you like the name! Lol.

It's just such a fun word. Say it out loud, "Juice!", "Juice Box!". It makes me feel like I'm 5 lol (and like I belong in a psych ward).

 

Lmao. So how did you just find out that it's called the JuiceBox?

I stumbled upon a PDF of it. At least I'm sorta sure it's called a juice box. Now that I'm Google-ing it nothing is coming up...

Also, Is my juice box the only one that's a PIA to remove?

 

At one time "JB" did stand for juice box (I saw this on the BMW forums a while back). I'm not sure if it still does.

 

The only way to really know for sure is to do it, but I would NOT if it was my car.

 

Well if 93=50% and 97=100%, then you're probably as high as you should go running 94 unless you upgraded something (intercooler, liquid injection).

 

JB stands for Juice Box. But we just go by JB now. Easier.

 

trader joe's sells a juice box as well:

 

I knew it stood for JuiceBox for a while, because Burger is so well known for their N54/55 work they have been doing over the last X number of years. I'm glad I joined the bandwagon and bought the JB+ for the MINI. awesome product!

I've had his tunes on my cars since 2008. Always a great product that keeps evolving and getting better!

 

IIRC, the piece of paper that shipped in the envelope along with the JB+ says "Juice Box" = )
