When I had mine I ran around 9 or 10 (20 total) at 18psi. I didn't know much about tuning back then and tried to get my a/f ratios around 11.5:1 which was way to lean on 92 octane. I managed to squeak out a 13.5 @99Mph with that setup.

I've seen some maps with 13 (23 total) or higher.

well where? what rpm and MAP?

My timing changes quite a bit ...

I will say this though ... drop it down inthe mid range and ramp it up to redline as boost goes down.

I run about 15 in the mid range and ramp up to 26 at redline ...

I run 94 octane

I ran a 13.5 @ 101 and with the stock turbo.

I will be back to the track in the spring ... and it will be faster. Doing many things to it right now

Your advance will look pretty much the opposite of your boost curve. Before boost builds you will have high timing numbers and as boost rises timing will fall. The low point of timing will usually be at the peak of your torque (not necessarily the peak of boost.) At that point you will want to run around 12-14 degrees of advance at say 17psi of boost (just aproximations.) From there your boost should gradually taper down and as it does your advance will rise. By redline it should peak again at around 22-27 degrees again depending on how much boost you hold to redline.

These numbers are gross aproximations and are based on 91-93 octane fuel. Race fuel will allow you to run more advance without detonaton. You should always advance your timing when using street fuel so long as A. detonation is not present and B. you are creating more power by doing so.

Here is a map of a 3rd gear pull at Wide Open Throttle (WOT) using a stock turbo and fueling system on 02 WRX. Notice the timing curve (dark grey) looks pretty much opposite the boost curve (green):



Always remember to add 10 degrees to what is displayed on the timing map of the Link. If you see 4 for example the actual timing is 14.

Hope it helps...

Hmmm from a low of about 10 to a high of 50 depending where on the map you are.

Timing is also dependent on the RPM's of the car. As the motor speeds up you will need to increase your timing to make up the time difference between spark and peak compression. This si where you get your most power, and how the DYNO results become so high.
