The cal is scaled to +40's but my fuel pressure is under 55 so I should see knock. I plan to raise the fuel pressure back up to 55 this weekend and start tweaking the cal to run without knock. I'm hoping to get 24 psi out of it.
The CEL I get did not show up the other day when the outside temps were around 40*F. It started to show again when the temps reached 55*F. So, I think I'm real close.
