Power Fc Sensors

[Sambo33]

Hi everyone. i have recently bought a power FC for my R33, i have not installed in yet, but i have a few questions. the fc will fix all of my problems regarding air/fuel, iginition timing ect, that the stock un-tuneable computer cannot.

a mate with an S15 was accelerating up to about 6000rpm when his aftermarket fuel pump failed, the stock computer immediately sensed this and shut the whole car down, preventing an engine failure.

i know the power fc would sense the lean-out of fuel, but would it shut everything down? or would the engine just die???

also how does the fc compare with the cold-start settings of the factory computer?

thanks in advance,

Sam

Sounds like bs to me...

lean out....ping and show knock...then die

so if a fuel pump were to fail, stock computer or not, you would end up with a blown engine?

The standard s15 computer would sense an open circuit and deploy what some people call the rich and retard stategy, hopefully averting a broken enigne.

or if the pump failed entirely maybe it just stalled?

Sounds like a little bit of bull to me..

As Mr. Duncan stated, possibly the fuel pump completely failed, loosing all fuel pressure, as a result no fuel squirting in to the pots = no bang.

Fuel pumps 'generally' start to slow the amount of fuel supplied, as a result the tune will begin to lean out and either melt pistons and or ping its self to death.

The PFC is safer in this respect as at least it will flash the dash light like crazy and display a knock reading.
