Thats weird about the AFM, I was under the impression they flowed well and only really need changing when going for big power as the tuning resolution is a better with a Z32 item. Mine's only running about 180@wheels anyway, and I need to get the sus/chassis sorted before I need anymore :(

Mine was maxed a little over 180rwkw as well as another mates.

Perfectly normal. You can tune them up to around 220rwkw odd but its a fairly rough tune. Essentially when the afm max's out you push in enough fuel at that load point to handle the boost being run. So what occurs is say its tuned for 15psi but the afm max's out at 12psi when it hits 12psi it runs the ignition timing and enough fuel for 15psi so not optimal.

But really you never try (thats if you were good enough to be able to do it) to hold 12psi at part throttle with the afm only just maxing out so usually it goes unnoticed. :(

The Z32 allows for a fair bit more scope. Mine went from maxing the std afm out to ~4.2-4.3v on the Z32. Then ~268rwkw was ~4.7volts and now 302rwkw is high 4.9volts on occasions flat 5volts on those cold nights. So nearing its limits again. :S

    • Yeah, whenever I say "HP", I mean HP. As in, at the engine. Allowing for a 25% discount from engine to typical Ozzie braked roller dyno figures, then subtracting the usual (more optimistic) US inertia dyno offset..... you get into the 600 actual engine HP territory from your 484 wheel number. 484 / 0.75 = 645   (that's Aussie rw intertia HP, converting to approximate engine HP. 645 --> 600 is discount for inertia dyno. Could actually be worse than that. But that would still be up around 600. So near enough for purposes.
    • Still fast enough to have fun (kinda). Time for a modern turbo with a divided turbine housing and a proper twin scroll manifold. I think 400-450kW is a great place to be, provided it's all in before 4500 rpm.
    • i'm not at 600 though 😢 its 484hp (356kw) at the wheels.. 
    • Nice. 600ish HP is probably a nice place to be.
    • In the US the EPA has been going after shops that sold aftermarket ECU tuning software that allowed you to disable CELs for things like EGR, DPF, SCR, or TWC failure. They also went after shops for selling emissions delete equipment. Their logic is that all cars built for street use have this emissions equipment and you cannot do an after the fact conversion to an off-road vehicle not intended for street use. Cobb, Hondata, and similar companies have basically all revised their tuning software such that going forward you cannot suppress DTCs for emissions-critical systems, nor can you toggle systems on and off in the tune like EGR. You also cannot adjust OBD emissions monitoring logic. You can still tune these cars. But you have to do things the hard way, basically. For example Subaru FA20DITs used to delete the TGV system to get spare analog IO for a flex fuel sensor. EGR also has to be dramatically pared back because without the TGVs the stock EGR map causes bad misfires. Now instead they have to implement the flex fuel system as a CAN bus sensor instead. IMO, this is heavy-handed but the EPA in the US gave so much leeway for so long and the aftermarket relentlessly abused that leeway to the point that they could actually see the effects of all these emissions-deleted work trucks on their air quality monitoring for cities that haven't met Clean Air Act standards. It's one thing to have a few people deleting emissions on their weekend car that spends 9 months out of the year on jack stands. It's another thing entirely for entire fleets of tradies driving around 8 hours a day on deleted diesels that emit 1000x the emissions per mile of a compliant vehicle.
