Hey peoples.
Just wondering if there are any actual benefits to run 12V straight to the pump instead of using the fuel pump ecu at all?
How can one tell that the fuel pump ecu is actually changing from 9v to 11.something V whilst driving?
Would or SHould i just be using the Bypass when on the dyno or track to make sure the FPecu doesnt suddenly lean out a tune?
Thanks for any input... Its something ive thought of in th epast but never asked.

The fp ecu also provides engine off safety cut out. So just use its output to drive a relay I'd guess?

Safety was my main concern(forgot to include that).
