Hey all howsit?? hope ur all well

I have a serious over fueling problem i just found out, i made a previous post a few days ago regarding a erractic idle, so i took it to my mechanic because it wasnt doing this when i had the car for the first three weeks. Now my mechanic told me its seriously over fueling and which is causing the bad idle, however he cant seem to tract whats causing it but says to start from the computer. The overfueling is so bad the car nearly stalls and i was told its damaging the engine because its washing the oil away.

I'll give you a list of whats done,

500hp walbro fuel pump
800cc secondary injectors
Remapped ecu

Now the fuel pressure regulator is most likely standard from what i can see. What i dont understand is if it was fine a week ago what went wrong??? Now i would love to take it to a rotary specialist however most of them dont have a clean reputation and ive been told of a shocking story from a close friend. The reason i need ur advice is i also know a tuner who is very good with jap cars doesnt get that many rotors but doesnt take up a job he cant do, my plan is to purchase a Apexi SAFC=II (fuel computer) and get him to dyno tune it, do think its possible to fix the problem??? Please any ideas how to stop over fueling at idle, the car runs perfect over 2000rpm and all the way to the buzzer.

Cheers !!!!!!!!!

 

so you're running rich................get an SAFC or any form of fuel controller and tune it.......the FC runs rich at idle to begin with and your larger injectors are most likely causing this... are the injectors and pump newly installed? What are your other modifications?
