I've got a PSI3 monitor hooked up and I'm looking at boost, knock correction, ignition advance and AFR. Now the car is an MY03STIPPP. What should I be seeing? Boost is around 1.30bar which sounds right, but what other figures are worth looking at?

I have had peak boost at 22.1 psi (1.53 bar) on my MY03STiUK+PPP . To be honest my secs is too far down in the dash (below hifi) to look to see what is going on when I am driving.

I really want to connect it to my in car PC and log the data at some point.

My STi7 shows the following SECS readings:

Max boost 1.34 bar
Water temp 83 to 97 C
Lambda ratio 0.76 on WOT to 1.56 trailing throttle, 1 idling.
Knock correction 0 to +11.5
Max speed .......??...
Injector duration upto ~16 ms possibly higher

My STi8 shows the following (during track session):

MAP: -0.85 to 1.30 bar
Water temp: 86 to 98 °C
MAF: 0.7 to 4.38 v
Throttle: 0.48 to 3.94 v
Avance : -1.5 to +45°
Knock correction : -1.5 to +12
Injector duration : 1.97 idling to 19.71 ms
Max speed : legal
Batt volt: 12.48 to 14.16

I've got to investigate a little further to find O2 sensor value in the ECU... most probably next week.

Cheers
