Hks Fmu
 

I have an old HKS FMU that came with my old turbo, I was wondering if any one would know how to hook up the vacuum lines, the electrical is no big deal?


Supra girl its very simular to the on you have pics of on your web site!

FMU?

i must be asleep right now coz i can't think of any device other than a boost controller that uses vacuum & wiring lol

I forgot to take pics of it last night but I will tonight and post the pics so you can see what Im talking about. It has the fuel map digm. and the window for the air fuel ratio. electric harness and a barbed fitting for vacuum lines take in consideration that this unit was brand new in 1984. I got the whole set up for free at a car show a few years back and I have finaly found a repair kit for the turbo. the fmu is the only thing i have not yet figured out how to hook up.

woohooooooooo

yes pics please :D

hopefully i can help ya out once i see it :)

I,ll have them on here by this time tomorrow. All the excitment!!!!!!!!!

here is my web page it has the pics on it.http://www.geocities.com/dragoneddie...1985turbo.html

i should probably imagine that it is very close to an fcon in it's wiring

where are the vacuum lines coming/going from/to?

The vacuum lines are coming out of the back by the electrical conection, My camera crapped out so I didn't get a pic of that. But thats the question I have the complete harness from the ecu to fuel computer and to the timeing retard system but do not know where the vacumm lines would go. If you look at one of the pics you can see the vacuum lines in the back ground, They are Y'd of I have know clue!!!!!

i would imagine logically that the vacuum would be manifold pressure

makes sense to me lol

Okay but from where to I just T off some where before or after the throttle body. or would it run to the fprv? and the T that is already on the line would that go to the timing retard system, because its got a vacuum nipple too?
