2020 M550 RK Tune

Just ordered the RK Tune for my 2020 M550. Got the cable, will be flashing it here pretty soon. Will report back on how the car feels. I MIGHT be able to get a before and after dyno tune done as well!

Are you running downpipes? Interested to see your results. I've watched Jordan's YouTube video on the 2020 M550i he tuned up to 644 hp

Check out Jordan's YouTube videos. I believe he tuned a 2018 M550i. Just search M550i RK Tune.

No. Im stock. Only "Mod" was me removing my resonators.

Im excited to see some gains. Hopefully I can get some dyno results, we have a fair bit of options of performance shops here so finding an AWD dyno should be easy enough.

I got the cable in and the initial file, but I was unable to pull the info off the ECU. Said an incompatible version. It MIGHT be the new flash I got from my dealership to have Wireless Android Auto, but Im unsure. Ill report back when its fixed and flashed.

Woah. Bootmod3 is available for the 2020/2021 models?? Nice! I don't even see it on the bootmod3 website. What does the ECU patch entail? How do you go about doing that? My 2021 is on its way and I plan on doing a tune and exhaust once I am done with the break in period.

You need to apply the ecu patch on bench in order to be able to flash via OBD. ( BM3). This can be done by an BM3 dealer near you.

Looks like there is only one dealer in Dallas... looks like I'll be giving them a call in a few months :-)

I just got a 2021 M550i a couple of weeks ago . Im waiting for the Dinan tune to be ready, as Im worried about warranty issues .
I did bring it to Atco and ran a 12.20 @119 mph. I only had three runs , Track was crowded and there were several breakdowns most needing a cleanup .Next time Im looking for high 11s.
If it wasnt for the Warranty I would ,get a non Dinan tune, remove catted down pipes, change exhaust and add a fresh air intake . Id like to get it into the 10s

Look up Carbahn. Steve Dinan runs it, I've heard not so good things about Dinan after they sold out to VC's.

They also retain the factory warranty and crank out wild numbers.

2021 M 550 mods

Thank you so much for this information. Your response is exactly why I posted . I dont want to make the same mistake I made six years ago. I bought the first C 7 Corvette in Ct . Immediately put a blower on it ran low 11s high 10s . Cranked up the boost ,on a dyno, blew the motor 🙈.
I will call Steve Dinan’s company Monday and see what they have or are working on. I will post the results .
Thanks again , Jim

The wild numbers is just crank numbers, but when they go testing in real world customers hang themselves after spending so much for nothing.

This is a good point. I can't find anybody running the Carbahn tune but the dealer I spoke to claims many are running with amazing performance.

They don't have the LCI M550i listed, so who knows.

Thanks for the reply. I guess I am a little confused. Protuning (and bm3 tuning) have the BM3 for the N63TU3 listed for $895. But, bm3 tuning also has it listed for $1,599. https://www.bm3tuning.com/g30. They are both listed for the 2020+ M550/M850.

What is the difference between the $895 version and $1,599 version? Are they the same thing? Am I missing something?

All the 2020+ model cars will need an OBD Patch/ECU Unlock to be performed prior to being able to flash through OBD (Bootmod3)

So, it is the same version, but the $1,599 includes the patch/ecu unlock, etc. ?
