Quick Question

Kobiyashi · 02-14-2004, 10:45 AM

Do normal knock a little when tuning???

What AFR should I run on 93 octane?

Should I lower boost and raise timing above 19-22 5k-7k, @ 17psi, or should I Raise boost and lower timing even more?

I don't feel like I have the HP gains for this setup that I should but knock is rather limiting me to anything, back of 2 degrees when I hit it.

Vs. an STi we are only talking about 2-3 car lengths from 20mph rollon to 80. I feel as if it should be better than this; should it?

besides your map that 20mph roll is one of your primary problem.
the wrx just does not do well from a rolling start especially
from 20-30mph which is between top of 1st and bottom of
2nd gears.

Kobiyashi · 02-15-2004, 02:44 AM

Not just that, I was using that as an example...

Any other input would be much appretiated.

You can only squeeze so much power from making timing changes.

You map looks pretty but there is room for improvement early on (10-50% @ 2000-3500 RPM). Without a log that map doesn't say much.

A way to tackle knock is to look at the value the stock ECU was attempting to make and go from there. I run anywher between 7-12 degrees of advance from that value. Start with +3 and adjust as you can.

I've read a few of your posts and can only suggest using MS Excel to plot where in your map the car is hitting when you test; and knock. That will show you how little of the map you use normally and where you need to make changes. I suggest using one spreadsheet for multiple pulls.

Example (one of my first conservative maps):
