For all of you guys out there that are running standalone or some form of ignition control that you can specify the total timing at a specific area, what are you'll running at 100kpa? Or basically what is your ignition curve at 100kpa?
Mine looks like this
RPM / total timing @ 100kpa
500 / 10*
750 / 12*
1000 / 14*
1250 / 16*
1500 / 18*
1750 / 20*
2000 / 22*
2250 / 24*
2500 / 26*
2750 / 27*
3000 / 22*
3250 / 20*
3500 / 20*
3750 / 20*
4000 / 20*
4250 / 20*
4500 / 20*
4750 / 22*
5000 / 22*
5250 / 23*
5500 / 24*
5750 / 28*
6000 / 28*
6250 / 30*
Now the problem is that I have to pull so much timing out between 3000 and 5500 that I feel a noticable power lose and EGT's start to climb noticably too. If I add back any more timing that whats shown above in those ranges, power picks up and EGT's drop, but my EMS starts showing KNOCK.. I cant hear any sign of knock and dont really show any signs of it either. I've checked my system and the knock circuit seems to function properly so I dont know what the heck is going on here.
The engine is internally stock and using standard US 93 Octane fuel.
Im curious to know what others are running timing wise at 100kpa with no known problems.
