Rough Idle and Electrical Problems.. HELP!

***TitaniumTT*** · 04-30-2010, 07:24 AM

I'm really curious to see what the dyno tells us when I test all the different ignition systems. To me, a CDI is just a band-aid for a near stock car but what I believe to be the better answer isn't possible with the stock ECU. While I completely agree with what you're saying Ted, I think a 4 coil system would be a better way to go than putting a CDI box on. The slow rotor speed, I would think, would want to see the slow burn of an inductive coil.
Personally I was running 4 D580 (LS1) coils and never had a hiccup at idle...... except when I wet fouled the plugs once after rebuilding an engine. Those coils I believe are inferior in the higher RPM/higher boost just becuase of a lack of ignition energy. Voltage not being an issue as my alt pumps out 14V @ idle.
Now get to combustion pressures higher than what I'm making and a CDI might give more of a benefit.
