Interesting that the Dwell tables are different from the B series to the F series. The B series seem to have a simple Dwell vs Volts and Dwell vs Coil temp (i think), whereas the FG's have an additional load based dwell table (which is an 8x8 table made up of 1.615 and 1.35 values). http://www.taipanmotorsport.com.au/sct-tune-upgrades
