 hi grumpy, i was thinking of some circuit in between my crankshaft sensor(variable reluctance sensor) and the ECU. Its because the engine will be running on natural gas for a while and the advance for the igntion has to be around 30 degrees for operation. The stock ECU map provides maybe around 14? degrees at idle. I just need to advance the signals by 10 degrees in order for it to run nicely. I'm not too sure whether a MSD timing box will be cost effective as it is a school project and my budget is not all that much. thats why i was thinking of a simple circuit to advance the signals from the crankshaft sensor, the result will be something like moving the sensor around.
