LOGS. APR Stage 3. 91 octane. Leak at compressor inlet. Bit lean?
Finally logged my car with ecux. I haven't found any APR stage 3, 91 octane logs so this is a good one for the archives.
I have a known leak at the driver's side compressor inlet, so some unmetered air is getting in. Am I running a bit lean?
I'll log again when I get around to removing the inlet pipe (pain in the ***) and see what's going on with the o-ring.
Does 4.4s FATS sound about right for 91 octane APR in an avant?
Stats:
Avant. ~4000 lbs during log.
Ambient = 65 F.
Altitude = 10 ft.
Relative Humidity = ~60%.
91 Octane.
APR Stage 3. Ver 2, 91 Octane code.
AWE Intercoolers.
APR Bipipe.
APR Stealth exhaust.
Piggie pipes.
BTW, Nye's ECUx Plot is the shiznit.

I think you read it incorrectly. The leak is on the INLET. So unmetered air is going in, not out.
All the metered air is going into the compressor and then some more is going in.
