2002 Ranger, 3 liter engine. Vehicle can't get over 85 MPH. At this speed
the engine seems to give out, kinda like it's starved for fuel.
I've checked out some performance chip sites, they alter the performance,
and almost as a sideline, increase the governor speed. That's more money
than we want to spend, considering we don't want the extra performance.
All that I want is to be able to increase the top end speed. On my sons car
(Japanese), the fuel pump is controlled by the ECM, so the question is, does
the ECM stop the pump at the preset limit, and starve the engine. His car
actually has a "test" connector were you can connect 12 VDC (as pointed out
in the shop manual) to turn on the pump. Can I just bypass the ecm in the
truck and power the pump with a constant 12VDC (enabled only while the
engine is turning, say from the ignition).
If the speed limiter is a safety issue, why is it so low. We'd be happy at
100 MPH. It's not like we are racing this truck, it would only be for
passing. The truck isn't used for carrying anything more than some hand
tools. Ford is really quite about details of the governor. The local
dealer claimed ignorance, that it even existed, till it was point out to him
in a very heated discussion, he check, and then admitted it was true.

Thanks for he help
