Should i just use it? I dont have the cash to get a chip/tuning right now.. unless someone has a hook up!

Someone give me some pros/cons!!

 

Ok, well i just went though some readings, and if im only boosting like 7psi i should be fine..

 

fmu bad

chipped ecu good.

 

Spend the cash now for a chipped ECU and proper tune.

Or spend the cash later for a new engine.

 

you talking honda? if you're doing the reading, you know that most of everyone on here is anti-fmu because they're unreliable, unpredictable, and not tune friendly. it's seriously not that hard or much to find a socketed ecu on here, and xenocron can hook you up with a reliable basemap for next to nothing. fmu was the answer back when options were limited and expensive as ----. there are so many other options now. on the other hand, there are a few guys out there that have run fmu's for miles and miles without a problem. if you've already got it in your head that you're gonna use the fmu no matter what, just expect to be thrashed if in a short time you're posting a "my ---- blew up. why?" thread.

 

for low boost, an fmu with a decent pump will work fine imho. But i mean LOW boost, dont get greedy. Back in the day i beat the snot out of a sohc i had running like 6 psi with an fmu.

 

these guys convinced me to get a chipped ECU and ditch my ganster *** E Manage and AFC Hack i was considering. DO it.

When you get the chipped ECU and base maps (cheap on xenocrons website) its not much more to get a mild tune to check your A/f and ignition to make sure your good to go.

(Did i do/say that right guys? lol)

 

I ran one for a year and a half at 5 pounds on a D engine. Stock pump and all. I never had any problems but I'm moving on to bigger and better things now.
I'd say go for it but keep the boost at or below 5 pounds which was hard trust me...

 

at 7psi your just fine i have seen cars run for years on fmu's

 

i bust 10psi .been 11 for the past year
stock d15b8
every day

burnin it up
(*knock on wood)

inline fuel pump, 12:1 fmu,

use it IMO

but I wish I could be chipped with a built bottom end
