Hi, I have a little test that I want you to perform on your engine. I want to do it for my personal knowledge, but I will share it with everyone else on this board or on other forum.

I want you to take a timing light, hook it to your engine and note the where is your timing where the engine is idling. Here's the steps to perform the test :

1- Start your engine and let it reach the normal running coolant temp (about 190°F).
2- When the engine is hot, hook up a timing light to the cyl #1 spark plug wire. DO NOT BRIDGE ANY TERMINAL IN THE DIAGNOSIS PORT.
3- Aim the crank pulley and notice what is the timing that the timing light is showing (It may be difficult because there is not a lot of timing reference (the reference is from 20° BTDC to 5° ATDC). I think that the timing should be between 15-25° BTDC.
4- Note what is the current RPM (your idle RPM).
5- If you have an aftermarket boost gauge, note what is the vaccum value when your engine is idling (it should be close of 19 in-hg vaccum)

Post your value on this thread.

This will be very helpful for me and for other people who are trying to build an ignition advance table on their Engine Management system.

Thanks in advance!

Sam
