My tinkering shall commence next week.

Them's the breaks.... or in this case brakes!
Will be interesting to see what happens audio wise as the inlets and outputs are hardwired but we’re driving different speakers in different locations..AnubisZed wrote: ↑Mon Jan 27, 2025 7:45 am My Saturday job was to upgrade my 676 amplifier, that I retrofitted last year, to a 677 system. New power supply, fibre optic and speaker adaptor looms were all made up and the system worked "straight out of the box" (** EDIT - after coding!!). The only downside is that the amp was from an E70, so although is the correct part the firmware isn't set up for the E89, so that's the next job to sort, but it is working as it should![]()
The only differences are that the E89 has the additional rear centre channel that I've added into the correct plug (four pin shared with the MOST), and that there is a minor change on the rear negative pins, but this seems to be working fine. So I just need the firmware update to match the E89 environment (Subwoofers in the rear and not under the seats, and the woofers in the front footwell instead of the rear 1/4 panel etc). On researching this, I should be able to sort this with ISTA and my ICOM. It's useable for now, just a little bassy, certainly works with the surround functionB21 wrote: ↑Mon Jan 27, 2025 10:19 amWill be interesting to see what happens audio wise as the inlets and outputs are hardwired but we’re driving different speakers in different locations..AnubisZed wrote: ↑Mon Jan 27, 2025 7:45 am My Saturday job was to upgrade my 676 amplifier, that I retrofitted last year, to a 677 system.

Yes I was referring to the firmware with its assumptions..glad it’s worked outAnubisZed wrote: ↑Mon Jan 27, 2025 11:46 amThe only differences are that the E89 has the additional rear centre channel that I've added into the correct plug (four pin shared with the MOST), and that there is a minor change on the rear negative pins, but this seems to be working fine.

I assume neither of these is fitted to an E89?sakamoto wrote: ↑Wed Jan 29, 2025 12:43 pm I used 6P Brembo calipers on an AMG CLS63 before, and I was trying to increase the standard 360mm outer diameter to 390mm with an adapter, but I gave up because the caliper curve and outer diameter were just barely within the limits. Isn't 380mm too heavy for a steel plate?
Also, there are twin calipers for the rear, what do you think?
In Japan, you have to pass a vehicle inspection for structural changes, right?
