Hey guys,

I bought an r34 skyline almost 2 weeks ago and yesterday went to check the tyre pressures. The wheels are 18inch and 225mm at front and 255 at back. The front tyres said their max pressure was 50psi and there was no such info on the back tyres (weird?). The pressures were down at 28psi so I pumped them all up to 42psi, was this right? Should the backs be the same as the front?

Also the front left is a Nexen, front right Kumho Ecsta spt, and rears are Falken Ziex. Is this a problem that there are 3 different types of tyre on the car?

Thanks heaps.

well whoever you bought the car from was somewhere between a super-tight arse and mad. I guess I can live with different tyres front and rear, but different side to side is downright dangerous in my book....you need consistent grip across the axle. and the thing is 3 of the tyres are terrible (nexen, ziex) and the 4th is not too bad.

if you want your car to handle well it is worth replacing at least the front 2 tyres. Not sure where you are based as you didn't fill in the profile, but you should be able to get ok to decent tyres at 200-250 a tyre.

no point buying one of the best balanced, affordable sports cars around and then trying to drive on shit like that. You might as well have bought a camry.

as for tyre pressures, 50 would be a max level, not recommended. I would normally suggest 32-38 (cold) pressure front and rear - lower for comfort and higher for handling. And keep them within 1-2psi front to rear as well so the handling is consistent

    • 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.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
