5%......tell me more.

 

The JCW Tuning Kit will not void your warranty. It is worth every penny as well, if you go with this set up you will not be disappointed!

 

I have tried searching for the kit by part number, but have had no luck. The part number I found through several searches is 11122359628. I want to check price and availability on line before I approach my parts guy and negotiate a price. I have been unable to find this part number on line. I'm not even sure what is included other than the programming. Any help would be appreciated.

 

Found this on ECS;

Okay, thanks guys. I just talked to my parts guy and he quoted me $1800 + ~$700 labor. Now I just have to wait for the results of my Diminished Value Claim from a recent accident to see if I can afford it. Found it on line for ~$1600.

 

Make sure the price quoted includes the tips

 

This is interesting, but is it safe? I understand that the JCW kit makes the actual power through the tune that they install- the exhaust is just for cool sounds. So maybe the tune adds 2 PSI or so. And NM adds, what, 3 or 4? Maybe 5 on the high setting? Is that combination safe?

Or- the BMS (which I have, and love) adds 3.5 PSI, I believe. You can use their software to customize that. Wouldn't you get the same results by bumping it up to 7 or 8? Which I think that some people are doing (check their forum)... maybe with 93 octane or race gas? Can we assume that's just as safe / risky as JCW + piggyback? Or is there some other magic that the JCW tune does that can't be replicated by a piggyback alone bumping the boost?

Apparently on low the NM module adds 3 psi and 5 psi on high. Not sure what would be the result of using the BMS or NM module on high - we didn't have a car set like that at our dyno day. Again, just reporting the data that we saw at the dyno that day

 

Yeah, of course. I forgot to add- thank you for running the dyno day and posting the results! I don't mean for my post to be negative. Just wondering things =)

 

No worries at all - didn't take it negatively . Wish we had more cars with different things on them to get data from . This stuff is very interesting!!

 

Probably. To put it in perspective, the B48 engine used in the Europe-only BMW 730i is rated for 258 HP and 295 LbFt.

It would be interesting to see how much boost the factory 730i tune runs. That would be a solid number for warranty-level reliability. The "de-tuned" JCW typically runs a peak boost of 16 PSI. To get an additional 59 LbFt would likely require another 6-ish PSI, just a rough guess. As such, a big handful of added boost on a Cooper S is no trouble.

 

from talking to bmw techs the 2.0 is a time bomb at any power level they talked about replacing many 2.0 litre engines under warranty.

The setting on my racechip is 7 without any hiccups or cel in 7000 miles. When I do the jcw pro tune the setting on racechip will go back to 1 at first.


I think the magic number for the b46/48 turbo is around 300 hp and the bottom end 320 hp.

 

mct thanks for the thread. I have a 2015 S with a dealer installed JCW kit and exhaust and just received my NM power module...looking forward to installing it this weekend.

 

The JCW tune seems to alter the AF mixture a little richer to allow more boost looking at the dyno graphs. Assuming all the cars were using the same fuel. There's also timing to consider. So if the NM just ups the boost using the stock fuel/timing curves that would be similar to the BMS JB+ for the N18. You can only go so far before you need more octane and/or meth.

 

The i8 spec B38 puts out 228hp and 240 lb-ft at 25psi.

 

my NM module arrives on friday. looking forward to seeing the difference.

also, does anyone have experience with the remus responder? i know how badly setup the throttle response is on modern cars. The responder looks like a good companion to the power module... I spent a bunch of money trying to properly modulate the throttle by wire on my 2001 mcoupe, the remus looks like a bargain...

If you are referring to the B48 would love to find more info on this.
How many techs, how many engines, and is this the crankshaft end play failure or multiple modes.

 

It also uses a larger turbo than the Cooper B38 to get that 152 HP/L, along with using the electric motors as torque-fill while the bigger turbo spools up.

Nevertheless, if we infer those numbers in terms of what the basic combustion chamber, pistons, and con-rods can handle (remember these B-series are all modular design), then a 2.0L *could* theoretically make 304 HP and 320 LbFt at 25 PSI.

FYI, More-BHP's Stage 1 ECU flash [UK bench-flash only] dynoed at 290 wheel HP and 307 LbFt at an undisclosed boost pressure..

 

Thanks Yesti- that's just what I was wondering. So the JCW tune is doing something that the piggyback tuners can't do. But doesn't the stock computer see the extra boost (or the mixture) from the piggyback and add more fuel / timing? Or that's only good up to a point on the factory tune, but JCW allows for more?

atlantaorange- thanks for posting that- first I've heard of that one. I know of the Sprint Booster, and I'd like to give that a try, but it seems pretty pricey for what it does. The Remus on the other hand, sounds like a good deal if it works out to under $200. But I wonder when any of these will be available for the F56... Any mini-specific vendors that carry Remus items?

 

You're gonna love it! I installed mine a couple of weeks ago. My plan is to get the JCW Tuning Kit around February or March.

 

That's what I was getting at, just didn't know the math to run the numbers.

 

The stock maps account for higher loads, assuming they are load based like the N18, with corresponding boost, timing, and AF ratios, with priority given to mpg, not max power, making fuel the limiting factor.

 

Sorry to get a little off-topic, but to answer agentorange a little further- I looked into the Remus Responder, and found that it has good reviews. For whatever reason, the main Remus site says they are priced at 169 Euros, which would be an amazing deal... but I don't see anyone selling them that low, in US or Europe. You can get them from Remus US for $250, but I just placed an order with Out Motoring. Free shipping, and a 10% off coupon through November, so it came to $225. Really looking forward to trying this thing!
