92 octane. That is the best we have here in ak. I usually do log iat's but they are always low here. What makes the knock come in so suddenly like it does in the pic above?

 

Man, I wish we had 92. We only have 91 here.

That's how knock usually comes on. the sensor hears it, and drops timing immediately.

 

I agree, you are in the 12.xx A/F range at peak torque. Thats the point cylinder pressures are the highest. Add more fuel in that range. Maybe upper 11:1 range. Then test adding more fuel and more timing and see what results in KR and what feels more powerful.

 

What is the best way to add fuel through edit?

 

Raise the numbers in the PE RPM table.

 

OK. I had to gently lower the timing to 13 in the hugh octane table and now I am getting no knock. I am now trying to dial in my pe-rpm a little closer.

2 questions:
How do you adjust part throttle afr?
when I am cruising and step into the throttle, but not enough to let it shift into 3rd, my advance goes WAY down, any ideas there?

I will get some more screen shots up in a little bit

 

The only thing I've ever changed is afr in PE. I have it set to go into PE at 40 % throttle instead of 90% or whatever it is stock. I don't even know if you can change it at cruise?

Do you have PE delay zeroed? Stock its like 1 second.(not good)

I've never really messed with part throttle timing, so I can't help you out on that.
