I just thought about this, i'm at work and I cant test this yet, maybe someone will know.

Now that I'm running a AEM EMS, did I lose the 9-12v fuel pump switching that the stock ecu does via the resistor/relay box? if yes, did the system switch the voltage to constant 12v or constant 9v (fail-safe mode)? or did it stay the same as stock.

side question. if indeed the 9v-12v pump switch system still works, is it time for me to cut that little wire and leave it at 12v constant?(running a TT fuel pump). Car runs fine, but I was just wondering with my current fuel set-up.(see sig)

Thanks guys
(If no one knows, I'll share my results when I get the chance to test the voltage)

I am unsure exactly. But the EMS has a constant 12V output just for the fuel pump. I am running my fuel pump off a 12v switched source for fuel cutoff safety reasons, instead of running from the EMS. Check your manual, but I do believe that the EMS is constant 12v
