Well i decided to pull my ACC valve off last night, basically because of the ongoing cold start issues.

The reason i did was that eaven if i wound the screw all the way in on the ACC valve, i couldn't get a lower RPM then say 600.

SO cleaned it up, pluged it up and all good workes well, the valve was clean, but i still can only get to 600 rpm.

NO i don't want it to idle at 600 rpm, it was just an observation.

I have set the idle as per procedure and seams to hold ok, but if i pull the ACC valve plug off the car will die, i suspect that this is correct?

I have tested the ACC valve with the multimeter and the computer and all work OK, as per spec.

Is there any way that one can test if the ACC valve operation is abnormal.

ALSO found that my Cold start valve is a bit stuffed, if you put it in the fridge it only opens half way, so it is never fully open when cold. I kinda bodged it up to do so, and it work a bit better, but need a new one.

Any idea on cost????????

The car still starts like a dog, leaning more to fuel injectors. I am going to deperesurise the system, and then push compressed air through the system to remove all fuel and see how we go.

Spoke to kutsie and he recond it has to be the fuel injectors.

well what i have doen since, is to remove all fuel from the fuel rail, by turning the pump off and pressurising it wil air, runnign teh engien untill all fuel was out of the system. There was nooo fuel at all, not a drop.

This morning i connected it all up, including datalogit, and started the car, still went like a dog, the data didn't swop up anything funny, except at cranking the voltage droped to below 8V so not sure if that is BAD????? this happens for propably 400rpm till the voltage pics up, could this be it, couls this couse my cold starting problems.

    • AFM looks to be a z32 The injectors maybe old Nismo 555cc The turbo tag when looked up seems to be a gt2871 , imagine it would have the bigger rear housing .82 all look like the mid 00's mods when he started building it up. Vac hose seems right but would need to see a diagram. Great work going up there and sorting it out, be a good club car for someone wanting a good reliable rig.  I know I would like to have it but no space and too many other race cars at the moment.
    • Heys guys I got a r32 gtst speedo is out by 10kph seems the faster I go the more it be out  just seeing if anyone else had to problem and knows how to fix it 
    • I can't agree. If we hadn't all been brought up with the noise caused by the inefficiency of an ICE, no-one would actually ask for all that. An EV is like any other car, it just goes better. 
    • 2 more things I have to work out Easy one first...can anyone describe how to pull the fuel pump and sender from a 33? I can feel there is some sort of mount and clips but don't have a manual and don't know the trick......if not I'll spend some quality time in the boot witha lighter tomorrow. Second question is harder.  He had changed the upper plenum to a plazmaman but clearly got to a point with the vacuum hoses where he said "f**k it, I'm going inside for a beer" and never came back to that job because it was a mess. Am I right to think that I need: 1. Pre throttle (16mm nipple on inlet) to AAC's main 20mm fitting as the main pre throttle feed 2. ACC has a second 13m outlet joined to that 20mm fitting which I think is the pre throttle air supply for the cold start valve? 3. Cold start valve's outlet fitting then goes to Plenum (to bypass throttle?) There is some adapter on the back of the ACC with 2 fittings (13mm and 10mm), do I run the 10mm through a 1 way valve to the Brake Booster (4) and the 13mm back to a 13mm nipple on the Plenum as the Idle control (5)? 6. Run a 6mm vacuum line from the Turbosmart BOV to the Plenum? 7. Run a 5mm vacuum line from the Fuel Pressure Reg to the Plenum? 8. Run a 5mm vacuum line from the Turbosmart Boost controller to the Plenum? (Wastegate already has a pre turbo pressure source running to the solenoid then the wastegate on the other side of the bay)  Any help appreciated, the GTR is quite different setup and while the Stagea also has FFP it is different again. (And no Dose, I'm not pissing it all off and putting a ethrottle on it....)
    • OK, onto some questions to try and speed up the process a little. Does anyone know what core this Garret is? I know it is a high flowed standard turbo but nothing else about it. Tag says OK 0169J - 446179-5032 Same question for the injectors, I don't know what they flow and ideally can work it out before it hits the dyno, they are a mustard yellow side feed
