Manhart MHtronik Powerbox for M8 Comp
Hello everyone. I recently took delivery of a 2021 M8 GC Competition which is juuuuuust about broken in, and I've been doing a bit of research on tuning of the beast. My previous M car, a 2014 F10 M5, had a Dinan box installed and warranted by the dealer and I was very happy with that, but it seems that they don't make anything like this for these newer cars.
Then I came across this: https://www.manhart-performance.de/s...petition?c=381 Clearly there's no mention of a warranty for the car with this installed, but it least appears that it can be simply unplugged when it goes in for service. Have any of you tried one of these? Any thoughts? Alternatives? Thanks in advance. BH |

Have you take a look on RaceChip?
They have engine warranty coverage too. I've sold a lot of them to F90 M5 and a few F9x M8 owners with a great feedback.

A friend of mine has Racechip on his F90, and he told me he could get it for me at a slight discount ($50 off), but I don’t need any more power, for now.

No. VMAX only can be done via ECU tune.
How fast are you planning to hit anyway? I did 150 on my X3MC and it still haven't hit the limiter.

In other posts, members have mentioned a very important point. Take great care of your BMW service adviser representative. It could really come in handy. Giving them $20 or more at each encounter is a no brainer. I had a great adviser at a BMW dealership and would get great service. He's even provided me with in-depth service reports on BMW's I've been looking at. Those reports are internal and not for the public.

Unfortunately, thanks to the coof no European Delivery for this one. So its unlikely that that I will ever need unlisted vmax. I would just a like it just in case. |

The only issue now, BMW start locking up the DME where you can't load the tunes through OBD2 anymore. The other option, you purchase M Performance Driving school (if I remember the name correctly) when you purchase your car, and they will up the VMAX after you attend.

I am not sure the DMEs have been "unlocked" if car production is after 05.2020 or 07.2020. My tuner said for example M8s produced until 05.2020 are "tunable" whereas the ones from later production months (in 2020) have the new by Bosch locked and double locked DMEs. I am sure people are busy finding ways around it, but has it been completely "solved"?

Says he can crack it and he do it all remotely. He told me he can. I haven't done it yet, so I can't verifying. But he seems positive. |
