And here's my basemap that I built from that:


As you can see, I have 18 degrees at 17psi.



Keeping everything linear and smooth is key as you can see in the 3D view.

Start with something similar to mine but retard the whole graph a few degrees. Then on a dyno, bump up the whole graph a degree at a time until you knock or stop making power then back it off a degree or two. At that point you're 90% there and just fine tuning is left. Ideally, you'd have a load bearing dyno to fine tune the cells in small groups from that point and extract the last bit of power/drive-ability.

This is the same map that did 293whp and 299ftlbs on an S15 turbo with poncams spiking to 17psi and falling off to 14psi by redline on a 95F day. Obviously, get your AFR's right first before you mess with the timing.

Hope that helps!

what did you use to make sure running all that timing wasnt causing knock wot? you use alot more timing everywhere than i do, and my map is basically the pfc base map minus a few degrees in a few places; pfc runs an aggressive base map iirc.
