cold start on 4agze

does anyone know the rough settings on the factory computer with regards to the cold start injector. Im running an aftermarket ecu (wolf v4) and for the life of me cant get a cold start out of it without cranking it for a week an messing with the throttle. For me this boils down to one thing not enough fuel can be supplied through the injectors, i guess thats why they added a cold start injector form factory... der.
The info that i require if anyone can help is the supply voltage for the injector, temp ranges and roughly how long it needs to run for so i can get this sucker started in the morn without hassles and without flooding.
cheers

This is probably not a great deal of help, but a start.
There are two senors on the back of the head, one of them is used to sense when the cold start injector should come on (should be easy to work out which one it is). One sensor is green one is brown, one measures the water temp and the other is for cold start.
On my 4AGTE I have an 86kw throttle body and the wax pallet is hooked up to the coolant lines (this works perfectly on cold start ups on mine running a microtech, starts first go down to minus 7 degrees), but the ZE throttle body is a little different I think, it's not quite so simple??
I don't use the extra injector on mine either.
Others who are more knoweldgable will probably reply soon and offer more help.
Cheers.

cheers, its a start, but the problem seems to be getting a good shot of fuel before the car starts which the injectors dont seem to supply enough, cause im giving it bulk injector timing at cold but still nothing. So i have to work out a way to get this cold start injector running.

The ZE injectors are more than big enough to start the car, if the injectors are maxed out at startup, I'd say you're running too much fuel and flooding the engine.
Getting an aftermarket ECU to start nicely is a bugger of a job.

i would be pulling some fuel out of it, sounds like your flooding it,
put some new plugs in as well,
i have never had a problem getting a car to kick when it is cold
