I just bout an adjustable jackson racing FMU, and it never came with any instructions, can someone please tell me how to adjust it because i'm not sure if its adjusted right, my setup is going to be a ZC using a 1g dsm turbo, w/intercooler, stock dsm 1.8" piping(will be upgraded in the future) so yeah if anyone has some info, please let me know, it came off a integra GSR running 6 psi off a supercharger, but i still want to make sure its adjusted right.
what should my air/fuel guage be reading while at idle with the FMU installed and also at 6000rpm what should the reading be?

 

i swear to god if you dont post in the right section i will de nut you.

please post in the right forum.

 

lol, sorry dude, i'll try not to do it again, its just that all this time i posted all my ---- there and no one cared. ne way can you answer my question?

 

i thought they wernt adjustable? u get disc's for then like 8:0 and stuff

just get a 12:0 disc..

 

ok.. I think you need a little lesson on how FMU's work.

they raise fuel pressure based on boost psi.
12:1 means 12psi of fuel for 1 psi of boost

which means at idle you will have STOCK fuel pressure.

at 6000rpm, you want rich for power. lean = bye bye engine

 

OMG that was funny!

Yeah, I don't think they make any that are adjustable. You need to change disks if you want to change the ratio. Your POS A/F gauge should be in the green at WOT.

yeah i know how they work, however my FMU, has a hex key nut on the top of it, and the guy who sold it to me said its adjustable, i have not played with it yet because i dont wanna mess something up, and in my next turbo setup that is going on the CRX, i will have an air/fuel guage.
but ne ways guys, what do you think this nut is for? could it be for adjusting the disc inside?

 

so at Wide open throttle its supposed to be in the green? and at idle its supposed to jump around from lean to green? well what about in between when the car is between 1k and 6k how fast should it be rising.

 

How fast should what be rising?

The gauge should be green when you have it floored and it will bounce all over the ------- place when it's not floored.
