Talking to ultimateray this evening both of our cars are autos convertted to manual. And we both have high idles when warm around 1500 and 2k with clutch depressed. Looking about it sems in the us they routinly knock down the idle speed after a manual conversion. Is this right and do I still need to do it?

More than likely the neutral switch not wired in so the timing is sat at 25* rather than the usual 15* iirc. My grey one was the same. Possible also needs base idle adjusting as well?

Neither of us have done the neautral switch I lead to belive its best left alone.

Can't help on this mate but is Phil keeping his now?

the neutral switch was done on my manual conversion iirc and it idles perfectly

i never did my clutch switch either, or the pin 44 earth, i just set the timing at 15degrees before top dead centre using a timing light. though wouldn't mind actually doing the pin 44 earth and then setting it correctly.

Does that not mean your car is 10 degrees out across the entire rev range? I was told that the car changes to 15degrees when the clutch is released for alower and quieter idle, when the clutch is depressed changes to 25degrees to help people not stall. If youve set yours to 15 degrees when its thinking it should be running at 25degrees is that not going to decrease performance all the rest of the time?

Yeah fine hes working again now so the old bumble bee will be back soon.

well, when i did my conversion i had a good scout around to see what the opinon was, but i have no switch on my clutch pedal, from what i gathered i didnt hear any one mention what you just did. some said just earth pin 44 on the ecu, others said just set the timing using a timing light once the car had heated up. i know one thing though, its not down on power.

 

But would still want to do it the correct way at some point.

Im very confused about pin 44 and ghe neutral switchm anyone care to expandm and yeah quavey thats how I understood it.

On my conversion, we temporarily earthed out the ecu pin, then set base idle

LOL so many different ways of doing this pin 44 thing, i think we need a definitive answer on this on exactly what the best thing to do is.

I very much agree did your idle high before you chsnged tge timing vs?

nope, just had consults saying the timing was at 25dbtc and it sounded like it had a slight missfire, once i put it to 15dbtc once the engine had warmed up, it purred like a kitten, and when you put your foot down, jesus lol

 

gives a nice little burbble like the sound of a rally car when you take your foot off the throttle, so does actually sound like it might be over fueling, (or the timing is slightly out when on the move)

 

Thats why i really want to do this pin 44 thing the correct way.

It's quite easy really, the best thing to do is wire pin 44 on the ecu to the neutral switch on the back of the gearbox, it's just one wire, the other wire on the switch goes to earth. Job done. Vods mate, it's nought to do with the switches on the clutch pedal, it's the gearbox one you want.

aaah feck sake, that mean i gotta get me car in the air again lol

Yeah also get the rally car burble, and some smoke. I assumed it was my tub seals but hoping its actually running rich. Pulls like a fecking train though.

yeah same here, and im only on 11psi boost at the moment. :D (i dont get the smoke though)

Where can I find this elusive pin 44?

Make up a loom that will plug into the neutral switch and run it through the gearstick mount hole (I drilled a hole in the side of the tunnel and used a grommet). You can then get to switch through the tunnel and don't need to get the car in the air. Just plu the loom into the switch via the gearstick hole, it's a tight squeeze but doable.

Have a look in the FAQ section mate, there's a ECU pinout diagram there.

not the best picture but does show it

if iirc my neutral switch already has a wire connected to it and its all wrapped up in some tape, i just left it as is, though im sure i might be able to reach it from the center console

So do we think pin 44 to neatral switch will cure the idle?

my understanding was that the timing is approx 25 degrees when engine is cold and adjusts to 15 degrees as the engine warms up to normal operating temperature.If you put a timing light on a cold engine you can watch the timing mark creep up to 15 degrees as the engine temp increases.

probably not but you'll have real difficulty setting the base idle if your timing is out.

well when my engine was up to temp, it was still sitting at 25 degrees out, so used the timing light to set it to 15, though it might not be advancing it correctly due to it still thinking the cars in neutral oops.

 

so do you run this wire from the neutral switch to the ecu, then just plumb it in permanently to the Pin 44 on the ecu? if so i suppose i best get on the case tomorrow lol
