Stormie,

Probably a bit late but if it helps....I had the same problem. Looked around at a lot of tyres (considered the Yokohama's 'cos they are OEM on the 370Z but couldn't get a reasonable price) but finally went with a newer offering from Falken, the PT722. I had not thought about that brand as my impression was just cheap passenger car crap, but these are actually pretty good tyres. I went up a size so 235/50-18 on the front and 255/45's on the rear and walked out with change from a grand!

And don't get caught up in the bullshit about speed rating - at 180Kph that's it, so why pay through the nose for a Z rated tyre?

The Falken's probably don't have the same level of adhesion as say a Continental tyre, but they do have a lot of feel when pushing the car hard.

For the price not a bad deal.

Because there is more to the speed rating of a tyre than the actual top speed that the car will go.

Its more about tyre construction, and torque handing characteristics of the tyre.

Not to mention voiding your insurance...

In SA (and I think other states are similar) the law says:

"The speed rating of the tyres fitted to a passenger vehicle must be at least 180 km/h ('S') when the tyre placard requires a higher speed rating than 'S', for all other vehicles a speed rating of at least 120 km/h applies ('L')."

So putting S rated tyres on any car won't void the insurance, nor is it illegal. In my opinion, if a tyre is rated to 180 kph (and you can bet there is a decent safety margin - the tyre won't explode at 181 kph), and I'm not using it on a track, I believe that the tyre construction & torque handling characteristics will be more than sufficient for our nanny-state speed limits.

Agree with you GeeDod.

The PT722's are rated V so 240Kph should handle it.

I understand that the higher the rating the better a tyre [should] be, but you would like to think that a modern tyre of this size and profile would provide the expected quality.

My point was more to the significant jump in price when you spec W or Z tyres when realistically most of us wouldn't push quite to the limits where we would notice the difference.

370GT SP has 19in wheels as std

370GT SP has 19in wheels as std

I think wogboy is bang on the money. I was going to say the same, and surprised nobody else has mentioned it. Each and every one of the 4 sp's my mates and I have brought out had 19" wheels.

So either;

1. It's not an sp model.....sorry

2. It's an sp with de-specced wheels.....sorry

3. I'm misinformed....in which case, I'm sorry

    • @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.
    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
