At least with burger, you'll have @r33 to easily help you because he is most familiar with their tunes. That's one advantage.

I'll have more of an update after this weekend. I'm planning a trip to Napa. It will be a nice excuse to put miles on the new tune. |

Ok, so I plugged the tune back in with S2=A. Here's what I noticed first. No CEL. I decided to drive and test how it feels and went to my grocery store nearby about 7 minutes away. The setting with A instead of B is very different - the throttle lags a lot perhaps even worse than stock or about the same. I definitely don't like this setting. I went to the store and came back 20 minutes or so later. Started the car, and the CEL returned. I called Paul of RaceChip back up and he told me to send him pics of the install, which I just did. He told me to put the dummy plug back in. I did and cleared the CEL. He said to drive with the dummy plug for a while (not sure how long) to see if the CEL returns with this to make sure the harness isn't bad. @42pilot, patience is definitely going to be a virture, lol. Any tips or pointers? He wanted to see the install before suggesting any other settings since I asked what to try next. I guess he really wants to know if the harness is the cause or not. Any advice is appreciated. I really liked the chip with S2=B. It felt like a monster.

So, this is confusing. This was Paul's response after I sent the installation pics I showed you guys above:
"Hello Omar, This location would be incorrect. Please see the attached picture. The wiring harness goes into the sensors at the intercooler towards the front of the engine. Thanks Paul" He attached this image, which doesn't really look like the F15 5.0i but may be similar?: Any thoughts? I told him the first installation didn't work with the connection he is showing. I used the 4720 plug (TMAP red plugs) for that and it put the car into low power mode with drivetrain malfunction and CEL. The 8720 plug however works by plugging into the same location as the BMS tune. Also, the 4720 plug is MUCH deeper and longer than the 8720 plug, which is why the 4720 did not fit into the the TMAP plugs that Paul is showing and only work in the MAF sensor area that bluelodge400 installed his tune into. 4720 (TMAP) vs 8720 (MAF) plug:

Spooling a turbo faster is done by creating as much exhaust gas as fast as possible - ignition timing (advance the hell out of it) and CORRECT fueling (too much will put the fire out). I am surprised your 4.6L V8 is laggy. My 550i had nearly the same motor (a few ponies less cause it was an '11), and there was no lag. That's why BMW installed two smaller turbo's rather than one big one or two sequentially. In addition, BMW has a great design to put the exhaust and turbo's in the center of the engine (down the valley) to all but eliminate lag. To prove that, the motor provides nearly peak torque at 1700-ish RPM. That's freakishly good.

This is exactly right. There's a slight delay in eco-pro and comfort modes in this manner where the engine is all ready to go and give power but it takes a second for the wheels to realize they have to go when the throttle is pushed down. @42pilot, you'd have to drive the 5.0i each day to really understand what X5Jouster and I are talking about. I know a few other 5.0i members noted the same feeling. This is what got me on the RaceChip idea in the first place.

Now if you plan to go in a straight line, big ass wheels and tires are stable BECAUSE they have rotating mass - think gyroscope. Spin those tires fast and they'll stay stable in one direction if properly installed and balanced. Try to turn them quickly though and you have a hand full of crap - no turn-in. Then if you want a nice ride (tighten up as you put it), you'll need a bigger, tuned suspension to absorb and dampen those huge meats tires/wheels (an increase in unsprung mass). If the shocks aren't adaptive or aren't big enough to handle the job, the springs and wheels/tires will overwhelm and you'll float merrily down the road. Then, think about the additional work of the brakes trying to stop all that additional rotating mass. It's a rabbit hole when talking about putting big wheels and tires on cars. But I guess they gotta look good...

It would be interesting to know when the torque converter locks (what RPM) in each of the settings (ECO, comfort, sport). I know for a fact that my 35d locks up around 1000 rpm in sport (versus 1200 slip in comfort) which gives the feeling that the car has "more" power. It doesn't - it's just how it's applied. The chip adds the power. For you, hopefully the chip manages the TC strategy too.

Don't ever plug in the way he recommended, as you have damaged the sensor and got away with it. Man, I was hoping that you got it sorted out already.

Yeah, but I guess I'm gonna have to be patient and see what happens. He didn't respond to me after I replied back explaining the two situations regarding the two types of installations and each plug difference. The CEL went away with the dummy plug, and I drove the car pretty fast in an open road with no one around just to see if the harness would cause any issues. None. No CEL, so I know that the MAF sensor plug install can't be incorrect, especially if the BMS install is done this way, otherwise, how could the RaceChip activate properly with this setup and the CEL go away with the dummy plug? Makes no sense. I'm guessing RaceChip didn't study the 5.0i engine as deeply as they should have? No offense or anger here, but why create a separate harness that works with a MAF sensor and send it to me if only the TMAP is the way to install?

So in April of this year I put the GL up on SwapALease and got a guy who wanted it and we went through all the paperwork. I placed an order for a fully loaded 35i M Sport in Mineral White, Mocha Nappa with the leather dash and yada yada yada. Sure enough several weeks goes by and the guy finds out that he'd have to pay tax on the lease even though I've already rolled my taxes into the lease. Well he backs out and subsequently I have to back out of the X5. The X5 was ordered on 4/30, arrived at the dealer on 5/23 and then sat on the lot until the weekend of 6/14(found out the hard way). Well my GL was parked in the street on 6/20 and a drunk driver doing 80MPH(cops estimated) hit my GL head on and his MDX flipped. Well my GL was totaled and the very next day I go to BMW thinking my preordered X5 that was sitting on the lot for 3 weeks would still be there. Well by the 4th week on the lot it was sold! You could only imagine the elation I had watching the tow truck driver tow my car away knowing I had my 'dream' truck(not really dream truck but you know what I mean) waiting for me at the dealer, only to find out it was SOLD! Well I couldn't order a 2014 X5 any longer and I couldn't wait till now to be receiving a 2015 by the end of August beginning of September, I had to look on the lots. Well there were very few M Sports and the 35i M Sports that were available were bare bones. I wasn't going to buy or lease a car I wasn't happy with the specs. The only alternative I has was to take an X5 50i and make concessions like the leather dash and door trim I really wanted or the LED headlights. Quote:

Those are numbers at the rear wheels??? That's over 575 at the crank with 12% power train loss. Do you have a dyno sheet for that? I would love to see where that makes power in the RPM's.

My 550 has the N63TU motor which should be the same as the F15 5.0 motor (just different covers) and my engine has those sensors on there. Burger tuning originally sold me a tune using those sensors for my car but later on told me that the tune wasn't effective anymore tapping to those. It was fine for the old N63 but for the TU bmw changed something so he revised the TU tune using the MAF sensors instead.

42pilot,
You seem to be a wealth of knowledge on the N63tu engine. I was hoping you could explain how the BMS Tune might work? Since it only attaches to the MAF sensor, does it only increase the air fuel ratio? Since nothing connects to the ECU or TMAP does it not change any of the settings that would give the vehicle even more power. I can’t imagine a few wires connected through a 2” x 1” chip would make that many adjustments to the engine. |
