:banghead: I just did a turbo set up on my 97 civic vtec but once i boost 7 psi and stop (like a light for example ) i wont accelerate and it will try to shut off and if i turn it off and then on it will run normally ....
...what can i do ?:banghead:

Hrm... odd. Could it be a vacuum leak? Do you have a vacuum/boost gauge? If you have a vacuum leak, it should register at low RPMs such as idling with no load.

Hopefully the Honda guru's can help you out.

Ahhhhh.....LIMP MODE. What are you running for fuel enrichment? SAFC, VAFC? anything. List your kit..mods all info will be helpful

more info is needed.

oksy there is no leak because my guage is estedy and just like it was on vacuum before i even installed the turbo .
i was told that i could run turbo at 7 psi with stock ex fuel pressure regulator .

i'm running a t3 turbo with 7 psi external waste gate and greddy intercooler and bov i conected the wastegate(top) port to the brake boster vacuum line and the bottom port to the bov and intake manifold..
my timing is set to factory's point that is 12degrees....

ones my car runs higher than 5 psi and fully stop i have to shut it off and on right away or i won accelerate ...

i don't have a map sensor bypass .. would that be the problem ??? or could it be that i'm running stock plugs set to .030 or fuel delivery problem..

cels? you need the check valves, go get a missing link. once your map sees boost, fuel is cut off. wont accelerate only in vacuum or after boost? anything covering the turbo inlet?

go pick up some injectors and ems and schedule some time on the dyno.

What I tried to say, my car did the same when I was running 13lb on the factory map sensor on a safc. I could never get a pass down the quarter because the car would always shut down as soon as i shifted 3-4. Go get the check vavles or like he said the missing link or I think a gm map sensor is like 75 bucks or so.

dont the stock map sensors handle up to 12 psi of boost?

yea but not 13. it wont do anything until you let off the throttle then the ecu cut out, I use to just turn the key off real quick while rolling and turn it back on and tadda, back to

who says the map sensor cant handle 13psi hell it can handle 17psi you just get a real nasty rich condition between 9psi and 16psi. but a motorola 2.5 bar is between $25-$30.

if you want to be super cheap then do the coolant temp trick and up the base fuel pressure then add some check valves. it wont be reliable but it will run

thanks for your replies i fix the problem i got me the missing link and i wont shut down .!! but now when i run from take off , first i won't boost on 1st gear (i don't know if that's normal) and second when im in second gear i get full boost but it wont go down on third and i have to shift on to 4th rightaway cause my boost is not going down between shift ....

any ideas.???:banghead: :banghead: :banghead:
