after install everything come with Drag turbo kit Stage1 GEN2...Car runs very nice in Vacuum mode in boost guage..As soon as I hit that first LBS of boost, Boom power fall on it face; cant accelerate any further...
I use check valve for map and FMU for fuel mangement..Dont know what my problems was for boost...

Wondering any expert Honda-tech out there can helpwill be appreciated..
Thanks

 

If the turbo is making boost, it sounds like you might be running lean as soon as boost hits. I would check out the FMU, you do have an inline fuel pump right?

 

it comes with the drag kits..it a Airtex High presure fuel pump....You think it running lean?..Most people I ask they said I run rich..
So, is that basicly my major problem..*FUEL*..
Or something else can cause this problem?

 

Go directly to a tuner with a wideband O2 sensor

enough said

 

Are you sure it's not something stupid like a blown off intercooler pipe?

 

but at 1psi? got a check valve on there? are you sure you have your fmu lines correct? did u remove the vac line from the stock fpr? polarity of your fuel pump right?

He wouldn't be seeing boost then... boost gauge is most likely being driven by a vacuum source off the IM so if a pipe is blown off or not connected properly then the gauge will not read boost because the IM is not seeing boost

 

How do you have the "check valve" installed?

Do you have a high pressure pump installed inline (before fuel rail)?

If so, is the polarity correct and is the pump running?

If so, is it pumping fuel the correct direction?

 

pick up a inline fuel pump

 

Pump running fine..smoothly, but little louder..Just hook up A/F guage; It jump like hell.. Rich to lean to rich to lean etc.... It just flying back and foward like a maniac..Just kidding..Yeah even at idle, fuel guage sence same thing lean to rich, back and forward..

As soon as I hit 3k rpm boost kick in on boost guage, car stall up, cant go further unless I release the gas and slowly press on it... Fuel should be enough cause I had 2 fuel pump running..(stock and Drag High Pre)... But the fuel guage is running crazy all the time, you guys think it was the FMU?? or something else?..Anyone know how can I set the FMU or readjusted??? or anything else that can help ..

Sounds like a problem with your 'check valve'.

MAP is seeing boost somehow and cutting fuel (reason why no boost)

 

you think it is the check valve?...I put 4 of them in..replace it with the map..
Any other reason how to install check valve correctly&gt;&gt;??

My opinion I think it was the FMU need to be readjust? was it?...Vortech FMU using.. How could I readjust it?..or chnge it setting to run better in fuel iconomy????

Buy a missing link and rid yourself of the check valves.

Do you get a check engine light once you hit boost? If you do I'm willing to bet that its your MAP seeing boost. If not then it is probably lack of fuel.

 

Anyways how can I check this fuel thing?..I think is my FMU need to be readjusted.. Do anyone know how to readjust this FMU??? I was planning to get a apexi AFC thing and 440 injector anyway, could this solve all my problem if I had them and get rid of FMU + check valve?????

 

How do you have the check valves connected. If they aren't connected the right way they won't do you any good.

 

Well I took out the map thing..use a plastic tube tap in that hole then run the tube with 4 check valve in that line...with ''T" fitting.. Between the tube I got it hook to valcuum line to map sensor.. Is that the correct path to go??..is very hard to explan the picture of a bunch of tube.... If that the wrong setup then please explain how you exactly you do the valve and I will follow it to see if I did it correctly or not...

Thanks for the post again

 

do you have anything covering your turbo inlet? any sort of filter?
Before, when i first installed my turbo, i used a shirt to cover the inlet. couldn't hit boost at all and car was so fricken slow. If u did the same thing, try taking off the filter and running the car again. Good luck!

 

check all your couplers get a walboro fp, and use a standalone and get some good tuning. You will be very happy

 

cant you try a missing link of somebody else.

maybe your computer is going crazy under boost because of strange map sensor readings.

 

once your map reads boost there is a fuel cut, I think somebody else already said that. Like I said in the long run hondata or AEM ems will pay themselves off

 

Hey guys..so if I get some other devices like hondata, standalone, or apexi afc could that solve all of my problem??? I mean the map and fuel cut, because with them I'm can get rid of FMU and check valves and my ECU can run boost after those install correct????

 

if your running the shitty check valves(fish tank one-way check valves... on drag for that) it takes a certain combination to get your car to run right...like it was stated before...does your car throw a check engine light when you try to boost???? Your check valves could be going bad(famous for that)even if you just installed them but sometimes it wont throw the check engine light on....best bet is get a missing link...it cost 60$ and will be alot safer then the fish tank check valves that drag sends...good luck..

 

My question is could this solve the map problem if I get good fuel management (hack,hondata, or standalone) and big injector.. cuase with this you dont need those darn fish tank stuff or missing link....

 

you will need a fuel management so that you dont have to run the fish tank valves or missing link...hondata or aem will do you good...
