I just recently heard about these things, the concept seems pretty neat.

I am aware that they are no replacement for a fuel map though.

Running pretty conservative boost pressures on my tercel, which has 155cc injectors (say 10 psi max on a T25), are these things reliable enough and will they provide enough fuel to not ---- ---- up?

I would like to hear some user feedback

 

FMU = Lame. There is no control. all it does is ups the fuel pressure under boost. They do work and it is the old school way to run fuel. You will need to upgrade your fuel pump because it won't be able to keep up and it will run way rich. Save your money and do real tuning.

 

fmu is junk

 

i think the fmu would ---- up the tercel injectors .. those are such low flow

 

people run fmus on turdcels all the time but i would recomend a better fp

 

fmu's are junk unless you spend big bucks... get it chipped, a lot more reliable and less room for error

 

no one makes a tuning program for a tercel so unless you want him to run a megasquirt fmu is his best option. remember it is just a tercel not a bmw

my bad... got ahead of myself. what you could do if you are looking to do it on the cheap side (still not very cheap) is get a fmu like apexi sells and have it tuned by a professional. i had an apexi neo in my prelude before i knew any better it did okay for what i had but was definitely not a megasquirt or anything like that. could go that route and retard your timing by cam gears/msd setup but if you go any of these routes your talking a lil money. but hey it beats spending big bucks fixing your blown engine.

 

try posting this in the engine management section. you might get better replies in there.
