    Sneak Peak at injector coding via INPA

    After a lot of reading and learning, downloading and experimenting, I finally got INPA to work with my ECU (many thanks go to nivedhm). This is a sneak peak at the injector screen. At this point, I believe I am capable of coding my own injectors.

    Few notes:

    The two 3-digit numbers actually have a decimal point separator. So if your injector has the following stamping on it:

    582
    227

    It actually means 58.2 and 2.27.

    In this screen you can see how these are entered in the ECU for injector 1:

    My next step is to verify that my currently installed injectors are actually coded in correctly! After that, I'll be replacing injector 1 in an attempt to rectify the misfiring issues I've been seeing.
    From all the things I've lost,
    I miss my mind the most!

    DUDE! Click here to enlarge I found that f* screen a long time ago but didn't realize that was what the numbers meant! lol great find...i need to check my coding as well...this is a huge discovery/help for our community...both thumbs up!

    Where do you get this software? What cable is used?

    Same questions.

    If guys can code their injectors themselves, big thumbs up!

    dzenno,

    I know that you were there buddy I know. A friend of mine helped me translate the coding dialog box. The dialog box tells you that a decimal separator must be put in. Further more, there is a screen in there which tells you the actual range of acceptable values for "energy" and "flow". The top number is "energy" and the second number is "flow".

    So basically, you are telling the ECU how at what energy levels the piezo electric circuit will operate and it also tells how much the injector will flow.

    I wish the damn weather will give me 1 warm weekend! Working on the car at sub zero temps makes it very difficult and is hard on the body. My fingers are freezing solid! Click here to enlarge

    This and whatever you would need to do when you replace the battery are important to me, thanks!

    wow, you may have just did something worthy enough for the community for me not to activley dislike you. good job on this one.

    does this raise more questions though about ACTUAL fueling limitations.... I wonder...

    Ryan, I think the battery integration can be done via BT Tool. It is in the activations portions.

    ah yes, but I only have INPA, ediabas, ncs, eldi, nfs. No BT tool at this time. And I really don't know what the hell I'm doing with the other software, but at least I don't have the seatbelt chime anymore!

    So I dug up a bit more. The flow rate is measured in milligrams per pulse. That's the second number. It ranges from sth like 1.11 to 2.8. The actual numbers escape my memory. My understanding is that this is a fixed value for each injector. For an example, my injector 1 will dump 2.44 milligrams of fuel per pulse.

    The way you would increase the flow is by changing how frequently the injector pulses. The more pulses, the more fuel will end up in the cylinder.

    We only need to know the max pulse rate of an injector to calculate max flow rate.

    Edit: I can only imagine how simple it would be for flash tuners to tune big turbo and upgraded turbos once they figure out how to control the individual injectors. I strongly believe that in order to do proper fueling, you need to know the individual injector flow rates.

    Very nice Vas! I've been meaning to learn the intimidating art of coding and now there's a big incentive to use ediabas ncs inpa d-can stuff

    I wonder what the numbers mean. I thought it was per stroke at first. I did some math to understand how much fuel we may use:
    Lets say 6000rpm 400hp which i think is apprx 200lb/hr of gas
    Thats 4mg/ms per cylinder and our injection window is basically the intake stroke so 5ms at 6000rpm
    Above fuel usage is constant, so 4cycle stroke is 20ms that means 80mg per stroke so 80mg in 5ms window.

    Oh boy who cares to check my work.

    As long as the ecu knows the flow (done with the coding) than its done . The fueling increase per cylinder is calculated by the ecu itself.
    if you need help with some german translations let me know.
    i just found a inpa version online. Just need to get the proper cable.

    Normally you would lengthen the pulse (i know little about DI specifics though), are you are saying there are multiple injector pulses per cylinder per cycle instead?
    Never thought I would see the day...

    This is my question. Can you lengthen the pulsewidth instead of having to inject in a truncated fashion which offers less resolution than one big pulse that is timed perfectly for each stroke @ RPM?
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    @enrita, i paid 6.95 i think for 1 month membership..well worth it...download took a while, hopefully it all works, working on installing all the $#@! right now...

    @Blaizon, progman has 2 cds, 1st cd is fine, 2nd cd is missing some rar files though and the extraction fails...its asking for rar 36 and i guess any others after that..know what's up?

    I am going to tackle the injector in about 1-2 hours. I put a space heater in my garage and unplugged the battery. Hopefully the fuel pressure would subside a bit. I'll try to take as many screen shots as possible while doing the injector coding. After that it is just a matter of typing it up in a DIY.
