C63s Multi map ?
First post here and have a big question 😅
I own a C63s Wagon and been really satisfied with it
Recently did a couple modifications but came across an issue, multi maps!
I come from a world of M and GTR so it was never really an issue (jb4, stand-alone ecu, mhd, bootmod etc) but it seems like for our cars is not as easy.
Pretty much I come here asking if any of you as come with a solution or knows of one
I know weistec and DME offer a handheld tuner that stores tunes and allows me to switch but they also force me to tune with them (I live in Portugal, EUROPE)
Follows bellow the mod list and a pic (yes it’s yellow 😝

KW V3
upgraded brake lines
Eventuri intake
CSF Radiator
reentech blow off valve
armytrix decat downpipe and full exhaust
upgraded Pure800 turbos
BMS methanol system
Everything else stock
Wagon was running 620hp and lil over 900nm on decat and map only
feel free to ask any questions, thank you!

I have that handheld device, its the same one I used on my M3, and you can purchase it on your own, or discounted with some tuners. WIth that set up you should easily be dynoing in the 700whp range. I personally use kevin baldi at golabworx in NJ for my tunes, because I prefer to tweak things, rather than an "off the shelf" tune. Heres the link for the handheld...

I used a mygenius handheld for a Eurocharged tune on my W204 C63. Super easy to use for installing tune files, but you have to reflash each time. I have seen other MB email tuners (as you mentioned) use different types of units similar to the mygenius, but they also require a reflash each time you change a tune file.
