How to check and set up base ignition timing?
Step 1. Following all manufacturer’s directions, carefully install a timing light on the cylinder #1 spark plug wire. Use all due caution here, as secondary ignition voltage can be as high as 100,000 volts or more. Also ensure that the timing light’s cords can not get tangled in a moving engine or burned on hot components. Step 2.
What’s the best way to read idle timing?
Use this number for your idle timing. Step 3: Rev the engine as you watch the timing advance under the timing light. Note the RPM at which it advances no further. Read the timing at this point. Use this for the cruise timing.
Where to find base timing table in Holley?
When you start the Holley software, you will see a button that lets you OPEN GLOBAL FILE. Click this, click “Base Cals”, and then click on any of the files that start with TBI. At this point you can click on the spark plug icon at the top of the window and you will see a base timing table with 16×16 cells.
How can I read the timing on my harmonic balancer?
If your harmonic balancer does not have timing marks you will need to use masking tape and a marker to put timing marks out to about 50 degrees BTDC. You can, of course, read the timing using a dial-type timing light but remember that those are notoriously inaccurate so at least calibrate it before choosing this method.

What’s the best Wot timing for a LS1?
Your log shows you have too much timing at WOT/high load (32 degrees)… The LSx heads are designed to promote fast burn, so mid 30’s timing (like SBC) willl actually hurt TQ (and the engine). I think you should be good with WOT timing at 27 degrees (unless you have dyno time to play with this to find best TQ wrt advance).
