3565, RE: Update Posted by Corbin, Dec-31-69 06:00 PM If it matters at all, there is at least one person running MSI V3.0 with spark in parallel with the stock ECU. I am still using the input circuit mentioned in that old thread. My tach wire is sheilded in the MS harness. I tapped into the crank signal at the stock ECU. The stock coil pack is powered and fired by either the stock ECU or MS (selectable for emissions). Power for the crank sensor (and all other sensors) is provided by either the stock ECU or MS (selectable for emissions). Injectors are powered and fired by either the stock ECU or MS (selectable for emissions). It probably isn't perfect, but I don't have any trouble rev'ing to 8k RPM. | |
