[DeTomaso] Speaking of EFI--Water Temp Sensor Question

[Ken Green]

 I posted the question to the Facebook XFI forum and all the responses were that both the +12V and ground had to be directly connected to the battery, and not doing that is a common source of problems.

 I assume you are not planning to only crank the engine :)

I would wire it up for best performance when running.

I’m using a Ford EFI and it has a table that adjust the pulse width depending on supply voltage, which compensates for voltage drop during cranking and heavy current draw when idling.
