Im sorry to bug everyone, but I need HELP A.S.A.P.

Iv'e installed a D16B VTec from Japan, into my 90' CRX HF.
It's Turbo'ed with a T25 and I have a Rising rate FMU (stock injectors for JDM motor) Rewired the injector clips. Also have a adjustable FPR. 7 PSI from turbo.

Now its in but wont run worth a crap. It Idels like crap , I check my fuel and spark , I have great spark and plenty of fuel. But it runs really rough and runs Idles really low. It also keeps fowling the plugs( dry , not wet ). Timming is correct , The map sensor code trips everytime I start the car, I've replaced it. But it still trips , I checked and double checked the connections and the vacume.

I really cant find anything wrong, so any info would be Helpfull.

Bryan, sounds like timing right off the top. Does the map sensor trip even when it doesn't see boost?

What ECU are you running?

Have you just tried to disconnecting the charge pipes to see if that changes anything?

D16B?? or do you mean B16B??
either way are you using check valves or a missing link?? You need to if you're using a FMU
Maybe there is something wrong with the swap if it doesn't idle right

Map sensor trips at start-up , its not seeing any boost,
also checked timing for a 10 or 12th time, it is correct.
Can you explain the install of check valves. And where can I purchase these.

Im running the 91 PM6 CRX SI ecu , the motor is a D15B VTeC


GGGGGGGGRRRRRRRRRRR, Im getting so pisssed.
