To many sparks
Posted: Thu Jan 24, 2013 9:17 pm
Hello, first time poster:
I'm working on a Suzuki GSXR600 2003 4cyl. motor for a Bonneville car streamliner project. I've fitted a Microsquirt 3.77 with a Quadspark to drive the ignition in wasted spark. I'm using the Suzuki COPs and the stock 8 tooth trigger wheel with one tooth ground off and the stock VR sensor. No cam sensor to make it simple. My problem is I'm getting to many tach signals some how. With a timing light on # 1 CYL. I can see two timing marks 180 deg. apart at cranking speed. When looking at the plugs sitting on top of the motor, grounded and firing, they all look like they are firing every 180 deg.
My settings are:
8-1 wheel, skip pulses 4
Dual/ multispark ign. options: I've tried , single crank wheel, and no dual multispark settings.
I've tried enable and disable auto trigger.
Some tries result in no spark at all and other combinations that work have to many sparks-tach signals.
Any input would be greatly appreciated, Thanks, John
