HELP: Stock S15 running EXTREMELY *Rich
Ran my STOCK JDM AUTO S15 SR20DET on a dyno today.
Fuel ratio was 10:1. At this stage, I believe there should be heaps of black smoke coming out. But there wasn't.
AFM was good. O2 sensor was good. Spark plugs was good. Timing was good. There wasn't any leaks spotted. Water temp and oil temp good. No boost leak.
Dyno equipment all good.
Injectors maxing out at 100% duty cycle.
Ran about 115rwkw. (auto).

So, what's the problem?
Can a blocked cat converter cause this?
