I was wondering if there is a way of adjusting the main spark table in TP5. I know how to add and subtract timing. My issue that my timing light is off 1.5 degress to the value in the same spot in the table. For example I have all timing in by 2800 RPMs 28.83* above 2800 at the same point on the timing light shows about 30.5*, I've verified this with 2 different lights. I'm only using the main spark table for timing, PE mode SA is all set to 0.

 

It depends more on the code than Tuner Pro on how you would accomplish this.

Make sure your base timing matches your initial timing for starters.

 

yeah check the base timing in the bin and whats on the timing light with EST disconnected. Make sure they match. Also you sure the balancer timing marks are accurate?

 

yeah, I checked base timing with est disconnected and its set to 8* btdc in the tune and shows that on the light as well..as far as the balancer timing marks, they were all setup by my engine builder

 

The other item is the latency settings. This table compensates for the latency of the ICM. And it caries between various modules.

See this link for more information on latency:
