Timing Question??
Timing Question?? I'm just wondering how you guys with HP Tuners or any tuning software, know how much timing they need to run for a certain type of cam or know what they need to do with a particular part up-grade. I'm trying to tune my motor, get the best out of it that I can, I just really don't know where to start with it.
Your best bet is to go to a dyno and increase timing until you don't get an increase in HP.
If you get KR back it off until it's gone.
I've seen alot of posts saying "Just increase it until you log KR, then back off 1-2 degrees."
This is not real safe, but has proven to be some what effective.
I never did the timing until after I went to a dyno day. Then took the dyno print out and made my adjustments at home based on the printout. I knew the rest of tune was spot on for fueling, so added timing at the dips in power.
If you go here you can see the difference having the info from the dyno made.

My next time to the dyno I picked up 200 ftlbs of torque at 4500 rpm and 80 rwhp at 6500.
