Base spark

[limited cv8r]

Do the base spark tables/maps have any effect on timing outside of ide conditions, can they effect your timing at part throttle or WOT?

[Doc]

Is this on an Auto or Manual?

My car is an auto, but asking just as a general question.

Refer to B5916 & B5917. Base is generally only used for idle conditions.

Depends whether your car is a manual or auto.
Holden Autos only go to the Base Spark table when TPS is below 1.19% and road speed of less than 6.4kph.
M6's drop onto B5932 at any speed below 410kph soon as TPS is below 1.19%
Then onto B5933 when in Park or neutral.

Typically, when I tune cars, I set the Base Spark reference in line with the Idle mode and Throttle Cracker settings.

Example:

Base Spark Closed Throttle B5916 - 1.19%
Base Spark Vehicle Speed B5917 - 255 MPH
(this puts you in the base map anytime you're under 1.19% throttle)

Max Speed for Idle B0107 - 4 MPH
Max Throttle for Idle B0108 - 1.19%
(set in line with B5916 & B4312)

Throttle Cracker Activate B4311 - 5 MPH
Throttle Cracker Deactivate B4312 - 4 MPH

This keeps timing simple (you know where to make changes if need be) and it keeps the active idle controls from interfering with the TC settings.

This is a post good info for anyone feeling their way.
For an ex-military simpleton like me I agree with it 100%.
Though if what they say is true about similar minds thinking alike, I'm truly sorry "SSpdDmon."

I can take it if you can...
