Hello, I want to go biturbo on my E39 25d DDE4.0 with the 286hp 35d turbos. I have the turbos, but I dont know how to wire the second "n75" and the electric valve for compressor bypass plate(pos. 12). I have the same ECU version that was used for Alpina D10, 7788016 but the Alpina had 2 electrically controlled turbos. Where can I find additional info, worst case scenario I go DDE6.0 but the wiring should be the same and I want to keep my original ECU because it is easier for the rest of the electronics, I am going to use it as a daily so I want to keep my abs/asc.
