5.7L Ignition Timing Table - Feedback

Honestly, my spark table looks kinda like the one in the OP. Past about 2000rpm, it's really hard to get the engine to spend much time between 90kpa and 50kpa, so I sort of get the top two rows tuned for WOT, and never really got around to modding the middle of the map. This might be why the 1800 rpm column, etc. look a little odd. Most people just smooth the map cosmetically after the majority of tuning is done.

ps - timing is the easiest way to adjust for traction in low gear, in cells that you don't really see in 2nd or 3rd, and that can make the spark table look a little odd sometimes.

pps - if you have the cells/resolution to spare, starting your spark and fuel maps in the cranking rpm range is recommended by Banish and a few other pro tuners. The ECU uses actual cell values instead of relying soley on guesses or extrapolation, and also makes the engine less "stally". I took advantage of that going from a 8 column Holley Commander 950 to a 16 column Holley HP, and the improvement was undeniable. My engine doesn't even complete one full revolution on the starter before it roars to life.

ppps - the WOT values below 1000 rpm show good thinking. Small advance numbers in these cells really help the engine rev up when you goose it in park or neutral.

IMO, it's these intangibles that really make the move to EFI worth it. They might not ever show up on a dyno or timeslip, but make it act like a completely different engine.
