Good Job!! Is this a "Plug and Play" unit? Or are there adjustments to fine tune it to your vehicle requiring a service tech? Exciting news, please tell us more. It looks like more wires than my TDC cr plus. How long to install and have you had any CEL lights to deal with? Last question, where can I get mine????
There are 5 points where it attaches between sensor and the engine harness.
Boost pressure sensor
Cylinder 1 injector
Cylinder 4 injector
Fuel rail pressure sensor
and Quality control sensor on the fuel pump (I think)
Also one attachment to the ground.
Mercedes installation has controller box mounted next to strut plate, in separated from under hood heat area, in my case, I ran harness through the firewal and mounted controller box inside the dash, next to fuse box.
Engine started and ran for the first time like nothing changed, no CEL, no RPM jumping.
I actually just came back from dealership, they activated my towing harness and ran system scan. Everything checked out fine, no remarks, Brabus box is invisible to them.
So far I feel no difference in operation, just performance is different.
I found my box on eBay, some nice guy from UK is selling all kinds of MB and Brabus parts. If I was looking for something similar, I'd get cheaper Spider box, stat is supposed to be even better:
You can buy directly from them, they will ship to US.
BTW, here is picture of inside the Brabus box (as far as I could open it), I suppose there is more than just resistors in there.
