I'm think of buying th estage 1 kit and having my mechanic install it. I know the intake and exhaust would be real easy but what about the software? Anyone one know anything about this?
Also, what is this overboost thing I see from the description? How does it work?
You could do the intake and exhaust, but there is no way to load the ECU software yourself (unless you steal one of MINIs computers/peripherals.) I'm not even sure if you could have a tuner load up the JCW ECU.
Overboost is just, when your MINI is pumping, the ECU says "Give it more boost" and you get more boost then a stock MCS, thus giving a bit more oomph.
so am I correct in assuming that the "overboost" feature is completely out of the drivers control?
Also has anyone heard of someone just bringing in their mini for the ECU flash while having everything else installed elsewhere?
What if I dont install the ecu software? What does it do?
Thanks!
Having the intake and exhaust only provides about half the power. The other half is gained from the ECU. If you aren't going to bother with the ECU you'd be better off just going after market and saving about $1,000.
If you install the other parts yourself, then the ECU flash at the dealer, you'll only save about 1 hour of labor, as the ECU takes ~2 hours, and the entire install is rated at 3 hours. Really not worth it in my opinion.

Not to mention that once hooked to the computer, the tech will have to do some updates BEFORE installing the software.
When I had my Stage I kit installed, there were 27 updates which took about an hour and a half before we could even start the stage I upgrade.

It is possible to load the software yourself but there are risks involved. Have a read here about retrofitting.

Firstly you need a Pass through tool, the only one I found that is below $1500 is a small one from Drewtech, called a "Mongoose", get the ISO/CAN version and they run at about $285. Then you need a DC power supply to hold the battery at 13v throughout the whole session. A battery charger will not do!! BMW recommend a 40Amp supply which will maintain the voltage even if the windows operated, lights came on etc.. I bought a 36A supply online that had a varable voltage from 12-15v it was around $150. You will also need a HARDWIRE network connection to your garage..wireless is risky..
Nevermind the extreme hassle and possible trashing of your computer but you'd have as much in buying parts as the entire kit was. I wonder why that guy went through that much trouble? Exactly how much problems was he having that he had to have some of the diagnostic abilities the dealer has?
Oh well, to each their own.

I'm still really confused at what it means when the description of the JCW stage says that "with the over boost function, temporary peak values of as much as 200 lb-ft are possible in the range from 1750 to 4500 rpm." when does this come on? am I the only one confused?

I'm not sure why you're confused
What they're saying is the overboost function built into the new R56's can get a little bit of free TQ when you hit the gas in the 1750-4500 rpm range.
Think of it as nitrous, they've got the software setup that under the ideal conditions, when you punch the gas, it allows the turbo to produce even more TQ than from the factory.... much like getting a shot of nitrous for lack of better description.
(the software probably leaves the wastegate open longer or something to that effect... I'm sure someone more technically knowledgeable can chime in)
Point is, it's free power during that rpm powerband range.

OP the JCW ECU remap, which comes on a CD that's VIN-specific for yr car, also takes into account the freer-flowing airbox and exhaust setup in addition to the overboost function. I took delivery of my stock MCSa last Nov, and I was able to feel the diff when I had my tune kit installed 6 weeks later--much more oomph on the low (<2K) and high (>5K) rpm spectrums. The latter can really be felt on the highway and track. Hell, I rarely use 6th gear until Im well over 95 mph--on the track, that is
But Im not a big fan of overboost--Id rather manually downshift to gain my power.

my mini dealer said they wouldnt honor warranty if i installed anything myself. even original mini parts... i think its a scare tactic, but im not willing to find out...
