7730 SA Table Definition Check
Hi Guys,
For the 7730 with the $8D mask,,,,
Base Timing = + 10 degrees.
SA Table (@ select kPa & RPM) = +20 degrees.
Is the "total" advance +20 degrees or + 30 degrees to TDC?
Best Regards,
Bruce

Thanks RBob,
That's what I thought. The SA Tables indicate total advance relative to TDC.
Just thought I would check.

Nice paper. A good read!
Given the $8D Mask, is there any ALDL Spark Adder to the Total SA?

Re: 7730 SA Table Definition Check
84Alky,
Is there a way to program the ECM to always use the "Closed Throttle" SA Table instead of going to the Main SA Table (100 KpA column) for temperatures at or below 113 degrees F?
I found a parameter at 0x31. Not sure if this is related to the Closed Throttle SA set-up?

S_AUJP v4 included this feature but it has a subtle bug which was fixed in v5. The READ ME FIRST....doc provides details on what to do to use the feature.
