Weber alpha kit
Can anyone confirm if a Weber Alpha ecu takes a feed from a coolant temp sensor. I've got a pre built car and cannot see a sensor for the ecu.
I've also gone through the installation instruction and find no mention of a coolant temp sensor
????

If its for EFI it will need a Coolant temp sensor otherwise iirc it just drops to a default setting
Wiring diagrams used to be available on the Webcon website

Ahhhh ok then
Are you using the Weber Alpha PI 150 or similar ? Which is just for carb's
ECU doesn't need to know water temp for computing fueling requirements if using carbs
Although it will have an Air temp sensor

Weber Alpha did a kit for webers using the PI 150 ECU ( plus another iirc )
It consisted of a pair of 45 dcoes and all the kit (TPS, Air temp sensor etc)
Westfield used to supply them as a complete kit
The catch is that the Early version of this ECU Cannot be re-programmed, not even by Weber Alpha dealers
The Later version of the ECU can be re-mapped though
Weber Alpha is a pretty reliable system
Only problem is its Weber Alpha dealer for mapping
