Sorry for the up
I am adapting a Mercedes SLK supercharger to my Sierra Dohc and I am trying to delay the ignition by taking the two octane adjustment pins to ground but I do not notice that it delays the advance, I am measuring it with a strobe lamp and I do not notice anything.
(My idea is to use an Arduino to connect those pins to ground when it goes over 0.15 bars and activate a 5th injector, more or less like turbotechniks did)
What I can be doing wrong? I am joining the two wires (brown/blue and brown/red from the 3-pin connector that are next to the coil) to each other and then to ground.
Thanks in advance! And sorry for my low level of English
