In tank fuel pump upgrade

[Loweredon33s]

Like said unless they disabled the variable voltage system then it's not running that high of a voltage all the time. There's an easy way for you to check and I can promise you most likely your custom tune did not disable it

Why can’t you believe that it could be manipulated by custom tuning just like the other stuff? Is the variable voltage system so sacred that it can’t be altered? We do it all the time man.

I take it you have very poor reading comprehension? As I've already stated unless it's been disabled the variable voltage system will regulate the maximum voltage that fuel pump's going to run. There's no magical transformer in the fuel pump module that would increase the voltage to the fuel pump.

ohhh boy what did I start! lol

A silly argument that shouldn't have started. It's okay it's not your fault

This is what we call "A solution looking for a problem".

It’s not disabled. An alternator can make additional voltage right? It’s manipulated by the tune to make as much voltage as it can at wot, it then uses that voltage for the pump. It’s very simple and my comprehension is quite fine. The charging system, just like the fuel system can be adjusted in the tune. It’s not disabled but broadened in its capacity.

My basic reason for the upgrade was to get it built, so we the ranger crowd could upgrade if we so deemed it necessary, now the upgrade is available thru DW fuel systems.

If you feel that's how it works then please go ahead and prove it. We would all love to see the data showing it does just that.

As a reminder my 2019 Ranger was tuned I Livernois and never did what you're talking about. Even at wide open throttle system voltage would still be wherever the PCM chose which was usually not above 14 volts
