I would like to know the same thing. I need to dissable it so it will never enter cold start. This is a temporary fix until i get my idle problems sorted. Anyone know where it is and how to do this?
Me too. Apparently there are 2 valves controlling idle. AAC valve which I have found how to clean and IAC valve (which I think is the cold start idle control). I would like to know where it is also so I can clean it. Someone must be able to help us!!!!!!pls

It's located on the underside of the inlet plenum, near Cyl#4 runner.

If you disable it, you will never cure your idle problems. You will have a permanent HUGE air leak.

It can't be cleaned. It is a bi-metal strip that is heated by current to close off a "gate" valve, thus preventing air by-passing the throttle plate.

Really? Basically i dont have the idle control valve connected at the moment (due to engine transplant) so to keep the car from stalling the warm idle is set to 1500. However In coldstart mode this idle goes up to 2200-2500 which is a pain in the arse. I was thinking since cold start idle should be about 1500 anyway i could somehow disable the cold start mode as essentially my idle screw has it in cold start all the time. Does that make any sense?

Open to suggestions,

Cheers,

Will

      Thought i'd update on this. I was able to get in contact with Craig Lieberman and later on Darryl Alison (owner of Kaizo Industries). Darryl was able to help me verify that my car was in fact one of theirs and is helping me find more info on mine !

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
