Hi guys, just came back from a tune at tilbrooks in adelaide by martin.

Tune was done at 16psi....at first we got 240 rwkw at 18psi but i decided to settle for 235rwkw @ 16psi as martin said r33 conrods and internals will not last too long will too high boost.

Your power curve looks nice and smooth, but your AFR's seem very rough

OK, not picking on the poster of this comment, I have deleted who it was for that reason.

But I am getting very tired of this slavish belief that having a flat A/F ratio trace is somehow a reflection of good tuning. It's NOT, all it indicates is the guy doing the tuning decided on an A/F ratio and then tuned to it. Any idiot can do that.

But (there is always a but) that ASSUMES that the one A/F ratio results in the best power at that rpm. And we all know that is CRAP, 12.X to 1 may well yield more power than 12.Y to 1 at certain rpm points. A GOOD tuner aims for a smooth power curve, not a smooth A/F ratio trace.

I know which I would much rather have.

:) cheers ;)

excellent result from the 2530, thats a great looking curve gotta be happy.

id say hes seeing 16psi by about 3800-3900rpm, as id see ~18+ at 4grand.

Actually, lets do an SK and do some maths :rolleyes: from the looks of the curve, he hits full boost at about ~110km/h. divide by 29 gives us 3793rpm (give or take, assuming 245/45/17) :lol:

saw your car there today by the way :)

Did you flow test your Nismo 555's? and did they all come in at about the same readings?

Nope...I did not flow test them, they came with a flow test report. Average flow was 565. Minimun was about 560 I think.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
