realeom.com says your guy was right, but BMW has disabled access to their official ETK on the German website so I cannot verify as realoem’s database is from 3/2019 so there could have been changes.

The springs were released before the Comp model so BMW had likely developed them on a base model at that time and did not bother with approving them for Competition models in Europe. Just like the wheels are M8-only wheels too, but they have the same specs as any other F90 wheels.

BM3 Initial Review and Stage 1 + 2 Dragy Testing


i have some Dragy testing data I wanted to share with everyone from doing some BM3 beta testing on my M5. I had bootmod3 on my F80 M3 Comp for 2 years and I really liked the platform. I have used a lot of tuners/ tuning platforms in the last 15 years ranging from old school EEPROM burns to ProEFI and Syvecs full standalone ECUs.

Things that brought me back to BM3 second time around:

Internal Logging – anyone who’s custom remote tuned before knows logging is a PITA. you go out do a pull, connect to the device, pull the log, email the log to tuner, wait for revision. in BM3 you just double click to start and double click to stop and the log sits on the cloud and can be viewed by you and your tuner or shared with car buddies via link. Viewing/ Trimming the logs is very easy and clean too, can be done on computer or mobile. You click on the fields to show/hide them to make log easier to read.

after log is complete, you can label it to keep track of what it corresponds to, so that you can easily go back and compare to previous ones.

Fast Flashing – the initial flash takes about 5-6 minutes all in because it has to do the ECU unlocks and there are 2 ECUs in this car. The subsequent map change flashes take 2-3 minutes, again dual ECUs. Both are fast, so changing between 93 and E30 is quick at a gas station.

Below you can see all the maps I have tested for Pump gas for example. They are all available for me to flash unless deleted.

OBD WiFi Agent – this feature is awesome. Allows to log and flash using my cell phone, without needing a laptop. A good thing for someone looking to jump back and forth between pump and race fuel maps. Lately I have only been using this to log and flash.

User Adjustments – I haven’t played with this in the M5 yet, but I used to in my M3. I would go in the settings and easily turn boost down in 1st and 2nd gears in the winter time for better traction. Things like turning cold start on and off are easy to do also.

I’ve had the M5 for about 2 months now and the best i got out of stock was a 10.84@127.5 MPH at the track with a crazy fast 1.59 60ft. Best It would do on the street was 11.1 with passenger 11.0 without around 125-126 MPH. The rest of my testing was done on the street. I have done stock, stage 1 93, stage 1 E30 and stage 2 E30 with catless primaries and secondaries.

So 10.45 @ 134.8 MPH and a 60-130 of 6.82 was the best I was able to get on completely stock hardware and just tune changes. It’s cold up here so I was struggling with consistency on launching the car, sometimes it would work, sometimes it it would just shut the lc down form wheel spin. I swapped the summers out for Michelin AS3+ 285/35/20 all around and now I’m cutting consistent 1.62 – 1.65 60fts in the cold. I also swapped all 4 downpipes to ER catless ones. I was originally only going to do the primaries, but after talking to several guys it seemed like all the faster cars had all 4 done. My friend had a set of lowers, so I bought them from him and put them on last weekend. The job took me about 5.5 hours, but doing it again I think I could do it in 3.5-4 hours.

And the result is new PB of 10.21 @136.xx and new 60-130 PB of 6.49, 0-60MPH in 2.56 with no roll out and 2.37 with 1-ft rollout which is how the magazines time these.

Now were are still in the process of finalizing the stage 2 tune, I am hoping to maybe see 10.1x from it and low 6s 60-130.

1/24/2020 UPDATE: Slight improvement to 60-130 on V2 E30 Beta file

Luxury Meets Legend: 2020 BMW 750Li vs 2001 BMW 7-Series

A new S-Class is coming out next year I believe and it will likely further the gap between the two. BMW just needs to do something different with the 7-series, the current formula just doesn’t seem to make it a better car than the rest of the class, and clearly it isn’t the handling king it once was so BMW needs to refocus their efforts.


This generation has always felt like a lazy effort overall. It’s certainly a good car and improved over its predecessor, but it’s lacking that X factor which the Merc brings to the table. I still remember revealing spy shots of this car being panned on this forum. It really doesn’t look much different from the F01 generation or the smaller 5-series. Interior design is also quite boring. The tech and materials/build quality are first class, but that’s not enough when the Merc just “feels” more special overall.

They had to do something radical with the LCI because nobody really paid any attention to this generation. At least they got people talking about it now. The 7er is really the weak spot in BMW’s portfolio, as the rest of their vehicles are among the best in their respective segments.

Base vs. Competition X3M comparison




Base vs. Competition X3M comparison

For those of you interested. I’ve been trying to figure out if the if there is any difference in the suspensions between the Base X3M and the Competition model. Luckily fortune smiled on me and I was able to do a pretty thorough comparison.

So two local dealers both got base X3Ms with 21’s and X3M Competitions with 21s. I did back-to-back test drives at both dealerships over the past two weeks (taking advantage of the 50 degree plus weather we’ve had here in NJ so I don’t slide around on rock-hard summer tires). Exact same roads/routes on both set of drives, so this was a really good comparison.

There is definitely a difference (not massive, but noticeable) between the suspension setups on the base vs. comp models. While it is certainly possible that the actual suspension components are the same, I wouldn’t be surprised if there is a difference in the software tuning of the adaptive shocks between the two cars. Having had the Dinan Shockware software flash on my ’17 340i Adaptive Suspension package car proves what a difference a simple software change can make to a BMW Adaptive suspension’s feel/performance

I’m comparing “comfort” mode on both vehicles here as that is mode I’d need to be in 80%+ of the time in order to keep some degree of comfort on the crappy NJ roads I drive daily.

On both set of test drives, I noticed that on small, rapid sets of bumps/undulations the Comp car seemed to “crash” over the bumps and really bounced me and the passenger around much more. It felt like the car was riding over the bumps as opposed to absorbing them. It makes for a very jittery and unsettled ride. Frankly, there is no excuse for this kind of behavior out of a BMW as they know how to make a car firm yet compliant. You could actually hear the impacts more in the Comp car as well. Surprisingly, the Comp models “Sport” mode seemed to handle small undulations better. Yes it was firmer, but Sport seemed to take the edges off the impacts slightly better. Weird. Sadly I couldn’t stand driving around a Comp model in Sport all day, but maybe those of you with smoother roads could.

I asked my CAs to pay attention to how they felt going over the same set of bumpy roads to help me see if I was being crazy or not. They both agreed unprompted that the base model seemed to handle the bumps better and that they felt the bumps much more in the Comp model. They also said that they felt they were being tossed around more in the Comp. I had a backseat passenger too at one of the dealerships (Genius was really interested in seeing if there was a difference between the two models) and she said that the ride in the 2nd row was much more unpleasant in the Comp model.

One thing I did notice (and which supports the Car and Driver quote about the anti-roll bars being thicker on the Comp models) is that initial turn-in on the Comp felt quicker/more responsive than the base to me. One of my test drives lets me take some really high-speed (like 60+ MPH – might have actually taken one long turn at 90) country back road sweepers and the improved turn-in of the Comp was easily felt. This actually made the steering feel a bit better/more responsive on the Comp as well. I felt more comfortable pushing the Comp through high speed turns as long as the roads were smooth. If there was any roughness/bumps to the turns, the Base model felt noticeably more stable due to the better damping. The Comp got a bit “skittery” on me on one high speed (50+) bumpy turn, which really shook my confidence in the vehicle. Proof that ultra firm is not always the best choice for handling.

I also quickly found out that the “Economy” throttle response mode is crap on either model. Put it in Sport if you want proper throttle response. It completely wakes the car up and almost makes it feel like they put a different engine into the car.

One other item if you care about 2nd row passenger space/legroom. The M Sport seats are definitely thicker than the base Sport seats in the Base model. I intentionally drove a second base model at one dealership just to see if I liked the base seat better than the M Sport (standard in the Comp, upgrade on the Base). After my drives I always get into the back seat to see how much legroom I have. For reference, I’m 6′ 1.5″ with fairly long legs and drive in a fairly proper “racing” position (seat back fairly upright, legs relatively straight, wrists rest on the top of the steering wheel while keeping my back against the seatback). With the base seats, I still had about 1.5″ of clearance before my knees hit the back of the front seat. With the M Sport seats, my knees were just touching the back of the front seat. While it is possible that I was in slightly difference driving positions as the seats are different, bottom line is that it looks the base seats in the Base model will net about 1-1.5″ of additional legroom. They are also softer cushioned and the seat bottom is wider (if you’ve got a big ass – stick with the base on a Base model).

If I could get the ventilation, I’d probably stick with the base seat on a Base X3M just for the additional 2nd row legroom, but I really liked the support/feel of the M Sport seat. Plus the leather is nicer and you can get the ventilation option, which I love. Maybe I can find a way to change the driving position a bit to get a bit more legroom for the rugrats in the back.

So right now, I’m leaning towards a base X3M with the upgraded M Sport seats. I’m curious if BMW will address the ride quality criticisms with the 2021 model. If they improved the “Comfort” suspension setting on the Comp, I’d definitely go that route.

I’ll definitely miss the better exhaust note of the Comp (yes, it is noticeably meaner/louder) but the power difference is negligible and can easily be solved with a tune. Ditto for the exhaust and black grilles and such – easily fixed problems, though they basically eliminate the cost savings of getting a Base model.

Overall, I felt really comfortable driving the X3M and am astounded with how much raw performance is available in an SUV. This really does feel like a jacked-up M3. Yes, you do still feel the weight and high center of gravity when pushing the car (compared to a coupe/sedan), but only folks with a lot of driving experience will really notice. I’d love to drive an M Drivers’ package car to see if the weight loss of the sunroof would make the car feel even better. It certainly couldn’t hurt, but not sure if I would really notice it shy of a racetrack setting when really pushing the car.

If you’ve gotten this far, thanks for reading my novel. . .

I’d love to see M start taking some more risks or being more creative with their engines again, similar to the bangle era with the V10 M5/6
and V8 M3, I don’t really care for them making electronic brakes and more and more items to configure with drive modes.


Really look forward to more high-performance hybrid powertrains but am concerned about weight. Hybrids usually add more weight.
AMG has made huge strides with their GT 2 door models being fun performance cars carving corners on the track and on the road rather than being straight line rockets.

All these 4 door models (GT63s, M5, E63s) as well as the M8 are just getting too heavy. I really like how our M8 rides but our AMG GTC easily out handles it

The other news is AWD coming to virtually all AMG’s, including the next GT 2doors…
