is this normal? what could it be? is there any way to "toggle" it to make it move with my manifold pressure?

perhaps you have the MAP hook-up wired incorectly

or check and see if the other gauges arent moving becuase if im not mistaken, there is a "freeze" button or something... maybe its "recall" im not sure..

hrmm i have a missing link check valve if that makes a difference

Civiclx

is it my check valve?

I believe that it is supposed to be in the negative's then close to 0 at WOT.

Recheck all your wiring to make sure that's not the problem.

hrmm even with the missing link its supposed to move? ill check again

are you running the AFC hack? if so, then you need to get rid of that missing link ASAP. the AFC hack works by scaling back the map sensor voltage output to avoid a check engine light and if you have a missing link, the map sensor isnt seeing any boost, which means the AFC is scaling back EVEN FURTHER the map sensor output. I wouldn't doubt it if you are running in the first column only of your ignition and fuel tables, which would mean EXTREMELY advanced timing and very low injector pulsewidths.

no im not running the hack, i have an fmu and missing link with the settings zeroed out

it would still move though.....my pressure fluctuated when my car was idling...then as I got closer to WOT..it go towards zero then a positive number

hrmmmm, just to make sure im correct the map sensor on my 1997 is split and connected to the yellow and white wires correct?

Civiclx

ish?
