^^ i saw your post. I think the core engine is still the same or they wouldn't be both called N63TU. Covers, intake routing all appears to be different though.

Wow that's some story there. Oddly enough my wife also had similar series of cars noted in your post - 2013 GL550 (too big) so went to 2014 MDX (too ugly ) and now we are with 2015 50i and she couldn't be happier.

I too feel the same way about turbo + tunes! You can get some real world performance at a very low cost! Seeing how well JB4 performs on blue's 50i makes you think twice about paying big dollars on the same thing from AC Schnitzer, Dinan, and Hamann. |

Ok, so I decided to completely take apart the engine area myself and install the RaceChip via the MAP sensors the way RaceChip designated this tune to be installed. Let me tell you...this is not an easy at all. However, turns out, my mechanic did in fact use the wrong plug (the 4720 - red plug). This plug absolutely does not work and I don't know why it was sent in the first place...I was surprised because there's no way it would have connected to the sensors - no wonder there was a Drivetrain malfucntion. The 8720 plug (pink plug that is shorter) is the right plug that plugs into BOTH the MAP and the MAF sensors. So, I plugged it in and did the whole install myself. I'm about to go drive my car right now and will report back what I find. I also set the RaceChip tune back to factory settings (I never touched S1=1, but I change S2=B back to B from A). Hopefully, this works without errors.
If not, I completely give up and will definitely be selling this chip on ebay for $400. Please excuse my frustrations and give me the benefit of the doubt. I did this install and guide for all of you. I hope it helps. If you are thinking about this chip...I don't recommend it if you want an easy install. Go with BMS for sure. The MAF sensors are so much easier to just plug into than having to remove things to get to the MAP sensors. I feel like I have a mechanic's strong forearms now....can't remember the last time I did a good forearm workout, lol. UPDATE: I just got back from driving in all 3 modes. The car is again much more powerful (S1=1 and S2=B RaceChip Ultimate TB factory settings) and there are no issues whatsoever. No CEL or any other alerts present. So, the install for RaceChip is definitely using the pink 8720 plug into the MAP sensors in front of the intercoolers. If anyone has any questions or needs any help, feel free to PM me.

Back to the topic. BMW turbos now put out ridiculous amounts of power

It looks like the ripple was there from stock.
It just being enhanced by the tune also.

Just an update. It seems that I might still need to let the chip settle, but @42pilot says this is not necessary if I read correctly because the car should automatically read/implement the chip parameters. The car only seems strong in Sport mode. When I was in Eco-Pro, there was a decent bit of lag esp at the higher RPM. Looks like I'll be trying the C setting next for sure in a few hours time after I run the car a little more. Might take a quick highway run before that.

I just personally installed the BMS N63tu Stage 1 tune on @Tcap F15 X5 xDrive50i. Installation was exactly as what @bluelodge400 stated.
It literally took only 2 minutes. 1 minute to pull the car in and open up the hood. The rest was just, unplug the MAF connector and reconnect with the tune in between, then repeat on the other side. I didn't drove the car, but TCap was happy with it.

It could be, but then the "tune" isn't much of a tune if it simply amplifies stock. There are some pretty steep cliffs early in the curves.

And in order to built a map from scratch, you are pretty much need to build the engine from scratch also and uses a MOTEC sort of ECU. Been there, done that, fun but very time consuming and headache.

Just an update, with stock settings, there is considerable throttle lag in Eco-Pro and Comfort (more lag here) in the initial RPMs, so I'm going to try S2=C and report back.

OMG...wow! I just got back from testing/driving the X5 on back roads and the highway. The S2=C setting was all I changed, and I can now say I have an official MONSTER in my garage. This thing hands down will be able to destroy my brother's ML63 AMG with ease. There is no more lag in any mode. Eco-Pro now has about the same power output as stock Comfort believe it or not. When I pushed harder and faster, there was no lag in the early RPMs and there was no loss of power/tapering off in the higher RPMs (some noted this in their 3.5 testing and I noticed this in setting B for Eco-Pro and slightly in Comfort). Sport mode on the highway really throws this thing into fast M territory and I confidently say this having driven my brother's ML63 AMG...my X5 5.0i picks up faster - the shifts were smoother and the car just kept going faster without lag/delay. Obviously I would need raw data and a real dyno to prove this, but I drove the same roads I normally do with both cars, and I kid you not...it was as if the car was a completely different vehicle - no exaggeration. I did a rolling start from the highway merge ramp at 15-20 mph and thought I hit 80 mph so fast...I was wrong and the speedometer read 105mph - I was shocked. No shaking of the car or loss of control whatsoever. Color me very impressed/happy. If anyone buys this chip, leave S1=1 and change S2=C.

Thanks, Ben . I'm really happy with this now. Still, if I were to go back and choose, I would go with the BMS because it's much easier to install and take out since it uses the MAF sensors rather than the MAP sensors that RaceChip uses. The other downside is if you don't do your own oil changes or don't have someone that is NON-BMW to do your oil changes (I always do full synthetic through Midas usually for all my cars), then you have to completely take this out (not easy remember) for BMW to do the oil change for you without setting off red flags. That's the ONE big hassle with this chip if you want to keep your warranty from being voided. Also, I had to cut the zip ties again (thankfully I bought 100 from amazon for $5) and take out the 6 torx screws to change the MAP setting for S2; it is a real pain in the butt each time because their tool torx tool is too short to keep doing quick unscrewing in one easy repeated motion.

On my 2011 F10 550, Dinan basically took the stock base tune as a baseline and re-tuned the car rather than altering signals. Awesome curves and performance. That's why their tunes are over $3000 (hundreds of hours tuning/testing) and BMW will install them at the dealer.

question regarding what to do if I wanted to get a dyno to see the difference. I planned on getting the baseline runs and then do runs after I plug in the chip. Would I get an accurate idea of the gains this way or does the chip need to settle in or adjust in order to see max gains?
