Where and what is the warm up regulator. what does it do?
-
It's bolted to the right-hand end of the block as you look at the engine from the front. It has an electrical connection and two high pressure fuel lines attached to it. The purpose of the requlator is to lower the pressure of the fuel system during the warm-up period of the engine. This reduces the pressure acting on the top of the airflow meter thus allowing it to rise easier, this in turn richens the fuel/air mixture.
Think of it as a kind of choke mechanism for an injection system.
Hope this helps

yeah cheers

you can get the WUR adjusted so that it lowers the overall control pressure on the car and makes it more reponsive & pull harder thru the rev range
i've had it done on mine and the difference quite noticable. but you need to take it to somebody who knows what they are doing!

Yeah cheers gambit. Thats my plan, just thought id find out a little about it so that it sounds like i have an idea of what im talking about when i take it to the garage. Im guessing that basicly the fuel pressure needs to be adjusted to 48lb/ft and that should do the trick?
-
aye control pressure should read 48psi with the valve shut on the measuring gauge
also, i need your address again!! i lost the piece of paper i scralled it down on d'oh!!

Ok will resend. Cheers.
