Hi there,
Every time the boost goes to zero from vacuum my AFR goes lean and beyond that. It feels like a fuel cut or something. The only way to get rid of it is to let the 2nd injector give some more fuel at this moment.
Now you are thinking...now what's the problem...
The problem is when I am driving with 140km/h cruise the extra injector is on and the engine goes very storch (rich)
Maybe my hardware install isn't right and maybe I change it today.
Connections now:
Fuel line goes to the 2nd injector, then a T-connection, the T goes to a Power boost valve pressure regulator, The otherside goes to the std. injector and the output goes back to the fueltank.
Pressure main fuel line is 4 bar and the vacuumhose should push it a little further on Full throttle.
Pump is 148L/H @ 5 Bar.
The std injector I don't know but it's on the max otherwise the cold start is not right (to much fuel)
If I change it then I will try this:
Main fuelline to the std injector T-it to the 2nd injector. Retour from the std injector goes through the PBV regulator back into the fuel tank. And the pressure on 3 bar.
Maybe it give to much fuel in low RPM and deflection but that should I compensate with the Piggyback (SMT-6)
The std injector should be able to run the engine to around 0.2 0.3 bar right?
And if this isn't the solution is it possible to place a LED light over the injector leads so I can have an indicator if it stops at that moment?
