hi guys i post nothing before but an old member since 1 year before.

Now just done my f22a prelude with ihi turbo, engine everything is stock just hooked up a legacy turbo, front mount intercooler.

after i start the engine it seem to be all right to me, the engine sound ok and no leak. After i test the car on road the first gear boost up to 5psi then the second gear same, but after the engine rev up to 3500rpm it climp up very slow and the car i can feel a little shake. Is that a fuel problem? or boost problem?

I got SAFC hook up but it doesnt seem to be working properly....

Should i need some kind of engine management or ECU chip?

Any idea how to solve this problem?

Actually, you registered today. :P

Is it tuned correctly, or did you just slap a SAFC on there?

gbydf

yes i got my id registered last year but forgot the ps, also HMT does require a membership to view the topic

The car hasnt tuned yet, I hook up the SAFC before i start the engine. I m not very sure if it is the safc gone wrong i ll take it off then try it on road.

What will cost this problem? and what should i do? bigger injector? or chip?

Did you install a larger size injector to scale back with the safc? Or are you trying to run stock ones? Any check engine lights yet?

gbydf

no i wasnt install larger injectors i thought the SAFC work with stock injectors?

yes the engine check light on and also when the check light on the TCS light cant be turn off(i mean it on aswell )

Any idea?

get some larger injectors.

That's usually the whole point of using an afc on a turbo honda setup...so you can scale back a larger injector to get more fuel in those cylinders

sorry about my newbie question again, is that a must to upgrade the larger injectors for the turbo charge, should i change the fuel pump and fuel press regulator as well?

or what about i take the safc off run with the stock computer? will that way the problem gone?


Thanks

you could change to a 4-5 psi wastegate. but that low a boost is pointless.
it's easier to get some dsm injectors for 40-50 bucks.
you dont need to change the fuel pressure regulator.
