Smile G12 Performance Improvements

Dear all,

I recently purchased a CPO 2018 750i xdrive M-Sport. It is truly a beautiful car and drives wonderfully. I previously owned a 2010 550i and an E38 before that. I love everything about the new 750i except for the acceleration, even in Sport Mode. This is especially true when merging on the highway or passing other vehicles. I know that the G12 is a different type of car and other options such as the B7 and M760i were out there. I believe I have reset the adaptive transmission from the previous owner (put the car into ON and depressed the accelerator for ~1 min).

I would welcome any advice on potential performance upgrades/tuning that would improve acceleration without damaging the car or invalidating my warranty. Now that BMW and DINAN have ended their formal relationship (and the DINAN upgrade would invalidate my CPO warranty) there do not seem to be many options.

Thanks a lot!

I don't believe they support the 750i G series yet. Not sure why. They support the 740i G11/12.

JB4 has a beta unit right now

I also have a CPO and having come from an F10 M5 I was so disappointed to see the G series lacks any performance parts. Even Dinan had more mods for the F series than they do the G.

I personally went with DME Tuning Stage 1. I remove the tune before i go to the dealer.

Either way, if you blow your motor, if they dig hard enough, they can find either products.

You are better off with the DINAN over any other product if warranty is a concern since DINAN will cover their product and any issues caused by their product that the dealer won't cover.

What about AC Schnitzer? They give you up to a 5yr warranty depending on country.

UK you get 3yrs.

Thanks a lot! I contacted the Dinan distributors in Tulsa and Kansas City and they have stopped doing the installation for some reason. Will investigate other areas.

Does anyone have experience with the Racechip system?

Hi,

Not sure what you mean about the acceleration, I picked a 2016 CPO with 35Km, the car is a beast especially in Sports Mode. The pickup is unbelievable considering the size and weight of this vehicle. I came from an E60 545i Sport which was also tuned and crazy fast but nothing compare to the 750ix. I would chat to your dealer and check if they have. another 750 to test drive and compare!

Also not sure if you can reset the adaptive transmission on these cars, I know this was a feature on the E60 but not sure if it is the same on the G-series.

Thanks Moopai for your feedback. I made an appointment with the dealer to have it reset. They said it can be done. Agree it performs better in Sport mode but would like more acceleration when passing or entering highway without changing modes. Might be the best option.

Let's know what the dealer will do and if you see any improvement.

Good Luck!
