| Post subject: | FPR question |
Hey Guys- Does anyone know if you HAVE to run the FPR vac/boost line tru the stock solenoid, or is it better to run the line straight to the intake manifold? Is there a difference? Does the solenoid bleed off some signal before going to the FPR? Any help would be appreciated. I have a leaning out problem at high RPMs and it seems the FPR isn't reacting or increasing pressure like it should. Thanks Guys. |

the selonoid wont have anything to do with your problem. it is there so you get fuel right at start up but it can be removed anyways. http://www.taboospeedshop.com/emissions.htm should explain this deeper. |

well....changed my FPR and still have fuel starvation on upper RPMs....any suggestions??? I am running a 4G61T with 14b, 450s, 60mm throttle body, 1G sidemount IC, 4G61T ECU, 2G GSX fuel pump, and the fuel filter is brand new. I don't know where else to look for the problem. Should I try using a 1G ECU??? Any ideas would be great. Thanks. |

You have any way to datalog the car? What boost are you running? I would venture to guess that the stock turbo colt ecu can't quite control the larger injectors and compinsate for more boost. If you can datalog look at the MS for the fuel injectors and see if where you are at in the injector duty cycle. Sounds to me like either go to a 63T ecu or get some way to add some fuel in. |
