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.

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
