Default WRX parameters

Does anybody know one place where I can get the recommended values/ranges for things such as a/f ratio, oil pressure, oil temp, coolant temp, egt numbers, injector duration,battery voltage, air flow, etc, for the WRX? The more the better.

I though I saw a thread a while back that had a few of these on it, but I coudn't find it with a search.

For instance, what temp should my EGT's be? What is too low? Too high?

My boost shows -.6bar. Is this normal? (It shows +1.16bar under load).

What psi range should my oil pressure be within?

What grams per second should the air flow be?

Other measurments like oil temp, coolant temp, injector duration, pressure, etc. - where can I find them?

I should be getting my delta dash tomorrow, my car is running fine, and so i assume numbers i log, should be normal. I'll post my info when I get that.

there are verous threads for the different ranges you're asking about. To my knowlege there has never been a single thread for it all.

A/F: 14.7 closed loop, ~10-11 open loop
Boost: ~20mm Hg vacuum to 15-16 PSI (stock turbo)
Oil pressure: 15-20 PSI (hot and no load) to 90 PSI (cold or high load)
Injector duty: less than 85-90%
Battery voltage >12v (probably 13-14)
EGT < 1600F under heavy load is the conventional wisdom

A lot of these measurements are going to vary based on your set up. Higher viscosity oil, bigger turbos, different injectors, etc...

285 is a wide tire!

Default

Boost stock is ~14 falling to ~12 at redline.

My oil temp with a warm engine is around 180-185 from the rear access galley, 195 under spirited driving.

Water temp should run between 175 and 215F, depending on ambient temps and activity.
