  1. Injector Timing

    in G4x

    Posted

    I am more familiar with using End of Injection, when I try to use that on a G4x it tells me if I plan to use a Fuel Cut in Seq. mode I should use Start of Injection. 

    Just wanted to understand why that is. 

    Thanks

    I agree, all inside of 1 box is nice but if you get a CAN controller it has some minor advantages and isn't much wiring... and with the Extreme you gain a couple inputs as well.

    I called Link on Thursday to get an ETA for the Fury and didn't get a call back. Now looking into the option of forking out the extra for an Emtron KV8.

    If you want the new X-series I'd do the Xtreme and use a separate WB controller (CAN or Analog) what kind of car? whats it being used for?

    Ive got bosch 980cc top feed injectors, its running around 43.5 psi base fuel pressure. Ive got the deadtimes and short pulsewidth correct in the ecu not sure if they are the right values to have. It seems the cars idle control also makes the problem worse. I added a minimum pulse width at 0.89ms, that was the lowest value before it started missing and afr was at 11 to 1 which I feel is way to rich to be drivering with. Should I try much lower fuel pressure? Or will it not be able to get as low as I want I do have an adjustable reg. 

    Dead times 

    10v - 1.689

    11v - 1.44

    12v - 1.245

    13v - 1.100

    14v - 0.989

    15v - 0.887

    Short pulse adder

    0.375 - -0.1

    0.500 - -0.2

    0.625 - -0.2

    0.700 - -0.24

    0.875 - -0.22

    1.000 - -0.2

    1.125 - -0.18

    1.250 - -0.16

    1.375 - -0.14

    1.500 - -0.12

    1.675 - -0.1

    1.750 - -0.08

    1.875 - -0.06

    2.000 - -0.04

    2.125 - -0.02

    2.250 - -0.02

     

    post the current map and let me look at your idle control stuff with the things you have changed... include log if you can

    if you look at your effective PW... it is quite low between .7 - .9ms   you could simply be lower than the injector can function and you are definitely in a non-linear range of any injector. 

    what injectors are you using? and do you have the deadtimes, short pulsewidth adder correct? what fuel pressure are you running? I don't see it in the log so I assume no sensor.  

    you could also add a minimum fuel injector PW and that might fix it, but you might not be able to hit that lean of an AFR at idle.

    Remsk2, you should look into setting up charge temp table, for IAT sensors that are mounted in the intake manifold it creates a bias that you can setup for ignoring IAT temps under certain circumstances. for ex. low rpm / idle you can have the table only watch ECT and once the rpms pick up and load comes up it can bias the other way. 

    hope that helps
