Okay ive just installed a drag turbo kit on 94 accord with a h22 in it, during the install i also installed a boost gauge and air/fuel gauge. The problem is when i took it out to drive it it would build boost fine but a 5000rpm it would miss and stutter horribly bad...Please help this is my first turbo project.

 

gap spark plug to .030, check you hook up FMU correctly.

 

Okay the just to check the fmu is hooked up with the fuel line going to the rail coming of the middle of the fmu and the fitting coming of the side of the fmu is going to the return line. and i will check the gap on the plugs

 

 

Check your MAP sensor.

 

how do i go about checking the map sensor...it didnt throw a code or anything...im going to check the fmu now

 

okay the fmu is intalled correctly...anything else

 

Did you check the plugs gap? Do not go above 0.030.

 

Also, are you sure you are not running lean above 5000 rpm?

 

did you install the check valves, missing ling, or do you have some type of ems???

 

the plugs are gapped a .028 and i will check the gauge again but i dont think i was runnin lean but i will check again in a minute...thankx keep them coming

 

Is there a check valve / missing link setup on this ?

 

yes synapse missing link...and just so everyone knows im running off of the wastegate spring right know 5lbs...also someone said it sounds like detonation...detonation would not make the car stutter right its just a ping in the engine...i will go out in the morning and see if it is going lean at 5 grand...anymore suggestions

 

bump to the top for the morning..

 

How are going to know how lean it gets without a true WBo2 meter?

 

sounds like its running lean. get it checked with a wideband

 

bump for some info yO!

 

what size injectros your running? also are you running a inline fuel pump ?

Alright im runnin 440 rc injectors with the vortech fmu and inline pump. A couple of days ago i turned the boost up to 9lbs and took the car out and it pulled all the way to the redline, but in doing so it broke a band-aid i had put on a broken stud in the valve cover. Anyways i got the new stud and put it togther cut the boost down and took it out again same thing 5 grand and stuttered like it hit the box. I called drag and the guy told me to re-gap the plugs to .035 (i had them and .028) and check to see that the pump was flowing right. im going to do this in the morning and see what happens...Please someone help im getting pissed....Sorry for the long post

So you are running the kit supplied FMU meant for the stock injectors with larger than stock units, and wondering why the car falls flat on it's face? Your spark plugs are completely black with soot, huh? Little hint here, "too much fuel." Can you infer where that problem is coming from?

You should apologise for not making your first post the long one, actually. Not to flame at you, buddy, but it's always best to describe your full setup in the post you ask your Q. Any one of these guys could have helped you with your problem within the first half hour of you posting it, days ago, if you had.

Take it slow, and come back if you have any other problems with the setup... don't beat on it if it's running wierd.

 

your forcing a crap load of fuel into your car if your running a 12:1 disk on that FMU. Check your vacume lines aswell....make sure there is no slack. I had the same problem when i tried to run the vacume source of the WG from a T all the way from the intake mani. I ended up taping the charger pipe for a source.

sounds like you got to much fuel.

 

okay an update i put the stock injectors back in today and took the car out and it pulled past 5 grand i thought it was all going great. Well i was coasting down the hill to go to the road and go for a test cruise. As i was coastin the car cut off, so i tried to restart it and got nothing. So i got and a pulled a spark plug to see if it was sparking. first off the plug was soaked in gas and when i layed it on the valve cover to check the spark and got a friend to turn it over, raw unburnt gas shoot from the spark plug hole. The fuel pressure was set to a stock 43 pounds. What does this sound like to anyone. It was so flooded i pulled the dipstick and the oil had gas in it. Some one please help

 

bump for some info

 

had the same problem. i didn't have an fmu, i was running an e-manage and 440's
it turns out that i was running too hot of a rating of spark plug. when i was tuned he tuned only to be drivable untill he could get more time to tune. so when i hit alot of boost the car would sputter pretty bad. it was from running too rich and not gettting the right spark to ignite the fuel. also i blew one of my spark plug wires somehow
