How do you set the total timing on a high performance engine?
How is it set?
- Determine your desired total timing.
- Set your Timing Light to your desired total timing.
- Start the engine.
- Rev the engine past the point where your mechanical advance is fully engaged.
- Watch the timing mark on the harmonic balancer using the timing light.
When do you set the base ignition timing?
And of course when you’re dealing with a car that you’re building from the ground up and you’ve freshly installed the ECU, then setting the base ignition timing would be a relatively standard step. It’s one of the steps in our 10 step tuning process that we discuss in our practical standalone engine management tuning course.
What’s the best way to set your timing?
It shouldn™t take much rpm to peg out the advance without the springs installed. With an adjustable light set at 36 degrees, align the stock timing marks with fi0fl when the timing is fipegged out.fl With the non-adjustable light, align your new 36-degree mark with fi0.fl Rev the engine a little to make sure the timing will not advance any further.
How to set your timing for peak rpm?
Start the engine. It may kick back a little due to the advance coming in immediately without the springs. If you™re using an adjustable timing light, set the light to 36 degrees advanced. Now rev the engine just a little while observing the timing marks with the light. It shouldn™t take much rpm to peg out the advance without the springs installed.
How do you find the timing number on a harmonic balancer?
Shine the light directly onto the harmonic balancer and find the number. Though the wheel is turning, the light should seem to “freeze” it at a particular number. This is the timing number. Note the number of degrees to the right or left of zero. As the RPMs increase, the point at which the spark plug is firing should also increase somewhat.
How to check ignition timing on a Harley Davidson?
At every 5000 mile (8000 km) service interval. Check for proper RPM and ignition timing as follows: 1. See Figure 0. Thread TIMING MARK VIEW PLUG (Part No. HD 96295-65D) into timing inspection hole. Be sure view plug does not touch flywheel. 1a. See Figure 1. Locate the proper timing marks for your engine.
