Spark table sea level

Min Value:

Max Value:

Description:This table is used for normal non-WOT operation and contains the total timing including the 10 initial at the distributor. A higher number increases ignition advance and a lower number decreases ignition advance. Base and Altitude spark tables are used based on barometric pressure. Barometric pressure above 26in/hg and the EEC will use the Base Spark Table while a barometric pressure below 26in/hg will use the Altitude Spark Table. To configure spark set all 3 spark tables (Base, Alt, & BDS) to the same values. Example: Assuming that you are using the stock X any Y normalizers, while waiting at the tree (drag racing) the vehicle is idling at 900 rpm. This puts the spark in column 0 (500rpm’s), at green, the engine accelerates to WOT. Before the rpm’s reach the next defined level in the Spark Table X normalizer, which is column 6 (2000rpm’s) the spark does not change. This is based on a 140% load from idle column 0 to column 6. Even though the table has 9 rows for spark it only reads what is defined in the X normalizer. In this case it is 2000rpm’s where the EEC will set the timing at 12 degrees and then column 8 (3000rpm’s) where will set timing at 20 degrees and so on.
