Motec ignition expander with 8 denso coils

[Daniel]

Hi

Just i am wiring up 8 ls1 denso coils to a motec ignition expander and wast sure if the ecu earth pin out of the coil was ment to go to A10 A11 (m800) or into the expander?


Thanks Daniel

Hi Daniel,

The ECU Earth pin on the coils should attach back to the expander GND, but this should be close to the ECU GND pins anyway, so wont really matter as long as the wiring is reasonably heavy from where you splice it in, to chassis GND.
