    Injector sizing problems

    in Fuel Delivery

    Posted

    The injectors where supposed to be rebuilt stock injectors upgraded from stock 285 to 325cc

     

    The duty cycle will go over 200 on certain parts of the table even during autotune.

     

    ...but does that mean from stock ecu->megasquirt injectors need to be replaced too or?

     

    im going to get these:

    thanks guys, they are 325cc injectors which is bigger then stock so this makes no sense.

    im really thinking its my settings in megatune, could yall tell me how it should be set up. for the injectors im also running a resistor pack instead of the PWM.

    I think im going to go 550cc injectors next now anyways so i can go ahead and eliminate that when i change them.

     

    Thanks

    hey i have a 240z with an L28et swap with forged pistons and 325cc injectors running a full megasquirt ECU swap rest of the engine is pretty muuch stock besides a BOV and FPR and Walbro

    my car keeps going lean above 3psi stock injectors are 285cc so? we are trying to tune the car but cant since it keeps going lean on the dyno even if the tables are maxed out. when we try and use the Autotune from Tunerstudios it creates mountains in the table very strange.

    I dont know if its a Fuel delivery problem or something to do with my megasquirt setup like the settings are set up wrong in Tunerstudio's, also the ecu is heating up

     

    Thanks any and all feedback would be greatly appreciated

    I have a question:

    I am doing a turbo swap into my 72 240z, i am swapping in a 82 turbo motor and harness, i have *most of the wiring figured out, but i am vastly confused with the fuel portion of things. my car was originaly carbed so i dont seem to have a fuel relay, so do i need to go buy a relay and make my own and wire it up that way and then run the blue with red strip switch power 5 sec wire to it and then i will be good?

     

    please any help would be very helpful i am very stressed about this at the moment
