My cartech fmu is adjustable on its ratio but it does not mention in the instructinos how sensitive the adjustment is. Such as 1 turn of the **** = + or - 1 part fuel:air.

I'm just looking for a general idea of how much a turn should affect it.

 

That would work if I had a fuel pressure gauge...damn those things are expensive. $195 from summit

 

Ghetto thats too ghetto

Can you mount a mechanical gauge inside the car if you use high pressure fuel line? It says not to from autometer and personally I dont like the idea of fuel in the cockpit either.

Anyways autometer says you can use it with their "isolator" ATM-5280 but its discontinued apparantly.

I suppose if I absolutley have to I'll get it...not looking forward to spending that kinda money though.

 

Well how about this...

Its cheaper and they have excellent feedback on all of their products. Matches my dash lights being red...Besides I'd like to have one anyways to see if I have any pressure drop... lean engine go boom boom

 

I'm also interested in knowing if these are any good.

I'll take a look at those gauges in a bit...

I mean if my fuel pump is being overworked or just decides to take a poop I'd like to know. I need to upgrade my intake pump.
