cheers for the link, it's awesome.
I have a 2TGEU motor, just with a modified 2TG therm housing to accept a radiator cap. This allows the radiator to be lower then thermostat. I didn't do this, owner before me did.

Okay, I obviously wasn't clear there.
I hadn't actually hooked that up, but was thinking I could use a pot to adjust how much fuel it flows.
But......... it's a time thing, ie: requires voltage to open, and duty cycle determines how much fuel it squirts.
So.... using a pot wouldn't work.
Some sort of circuit to control the duty cycle would have to be created and be changeable by some sort of pot.

So........... I was thinking I could just power the cold start for 5 seconds or so when i crank the car.
I presume that running the engine in "warm" mode won't be too bad when it is cold.
I don't have the oxygen sensor plugged in either.

Brainwave #2:
If i just put a potentiometer with a scale similar to that graph, I can just adjust what the computer thinks is the temperature, and in turn the mixture 
I'll get a pot tomorrow.
