Ive gotta see my uncle on the weekend, hes an SS driver, and he always points out my 'rice racer'

i need a timeslip to stick in his face.

Rocko eh.

I used to live down there, dad still works down there, so ill give him a ring and see whether theres a nice breeze in by then.

Just got back from the drags, I'm kinda happy but still dissapointed with my times.

Got a few flat 14's out and a best of 13.9, but the car had shitloads in it, it was the driver that ruined it.

EVL R33 got a best of 13.4, of the runs I saw, but he may have bettered it. We were swamped by the number of STI's, all running low 13's or better.

It was a bit of a poor showing from the Skylines, with only a handful there, probably the hot weather putting people off.

The heat was unbearable as the start, and even at 9:30 was still uncomfortable. I think times may have been slightly down due to the heat and shitty track conditions, better traction on the normal road, but there are no excuses.

I've got a twin plate clutch and no matter how many ways I tried I just couldn't get a decent launch, usually lighting the tyres up through into 2nd. But if practice makes perfect then I'll be down there next Wednesday.

I must say that to all who told me that low tyre pressures work, you were dead right, and doing a burnout, with the tyres Hicks not the clutch, also helped. Other than that with top speed at 170km/hr I should have gotten a better time, so I'll be there next Wednesday early again.

I would have gotten 15 runs in, pretty good value for money if you ask me.

Yeah, I suppose I shouldn't be too disappointed, I think I'll have a better idea next time. It will be good fun racing one another, as we should be pretty close. I had the top end power to roll most of the other Skylines and 300's and some V8's, but everybody got the jump on me big time.

Looking forward to next Wednesday already.

meh.. with mid to hi 13's i'd say u must be running the slow v8's most gen3's down there are atleast pulling mid 13's nowadays :P

not to mention wheel standing torana's and the like. Altho there are a fair few slow v8's there, try lining up an unasuming grey VT HBD with BBS hockmesh rims. just bolts ons and a new Torque converter, should give you a run :)

Well, sort of happy...

best of 13.6 @ 102mph, 60' of 2.00 (best of the night 1.8).

When I got a good start, I stuffed something up (read missed a gear, damn shortshifter:D ), and when I had good top end runs I bogged down..

But practice makes perfect so I'll be down there again don't you worry. Had a great time, met Paul and a couple of other skyline owners.

Don't get me wrong, some of the V8 guys have awesome cars, like the totally bombed torana's, but I was sursprised that I managed to run down some of the others, I expected more top end from them. I think one of the torana's managed to just get into the 9's.

It was a great night, and nice to see EVL R33's new ride, even though there was one almost identical down there. I hope conditions are a bit more favorable next week, and they prepare the track better, but I'll be there trying to improve my times.

    • @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.
