PPPPPS Anyone want any stainless headlight springs while I'm rummaging around in the loft and playing Postman Pat?
PPPPPPS Anyone want any Wilwood nipple caps......

The clever bit was working out a simple algorithm that could be programmed into the PIC but it is almost perfect now. Unfortunately I used a tool called Flowcode to develop the code but my evaluation license has expired and I haven't found time to either load a new install and try for another trial or to reverse engineer the code. All I know is it works well on my car and apart from a minor modification to the mark-space ratio at normal running temperature and dropping the fan threshold (for purely psychological reasons) I'm happy with it.
PS I could post a circuit diagram but without the updated PIC code, it's not a lot of use!

I just paid an extra 2p and bought the next spec. part up the list.

That bit is in an infinite loop obviously - how else did the pc evolve?
