  1. 3sgte unstable ignition

    in G4+

    Posted

    Hello guys. 

    I have a plug in link g4+ for 3sgte with COP setup. 

    I try to set the ignition with the timing set feature with a timing light. 

    I set it to 0 from pclink. 

    Some times hit 0 at pulley some 5 some -5. 

    Why it is not solid?

    if it sprays before IAT sensor....but he said he doesnt use methanos spray

     

    also what d you mean " Almost looks like electrical noise "

    I would assume IAT would follow this trend.

    You can get electrical noise/interference when you run sensor wiring beside items like coils and alternators. At around the 6600rpm mark the IAT drops randomly. Not the reason why the engine blew but IAT should follow the trend like the pic.

    Some strange settings, but fuel seems to be fine. IAT´s are strange unconstant.

    Knock control isn´t setup as it should be! Can´t see, if it was knock related failure. 

    However i think ignition timing is 3-4 degrees off, what i have seen to other high power 3sgte´s.

    Is the ignition timing matched between engine and ecu?

    Could you let us know more about the setup?

    Early Gen3 3sgte tend to blow the cylinder wall with forged internals.

    Well guys, today I strip the engine to see the damage!

    About spray no I don't spray.

    About the IAT maybe was of the poor connection but if I remember it doesn't affect the timing at that point.

    Before a week I was on dyno  and the fine is knock free.

    The timing is synced yes.

    I believe that the COP setup maybe run out of durable spark at 12v. What do you think about this?

    Are you running a methanol spray? Your IAT is all over the place. Can you post a map?

    No I don't have methanol my friend.

    I have an open element link IAT sensor

    I will send a map later.

    Do u have a log of that run that it blew?

    I have a log from ECU.

    it would make sense for it to run lean if it dropped to ~12v and your injector dead times were badly off for that voltage, and that might cause knock, but you would see the whole log go lean, and at high RPM dead times dont make that much difference. Knock control probably would have seen it too.

    If the log shows good AFR, and it also shows the timing to be sensible values, then i'd be looking at a mechanical failure in the engine. Oil and coolant level ok? head gasket maybe?

     

    I was about to tune the knock control yesterday but I haven't that chance now.

    If the injector cut was very minimal just one or two injector events, the wideband can see that?

    sounds VERY unlikely. Are you sure you have cause and effect the right way around? several things failing in an engine cause cause the alternator to stop, or an electrical fault may have caused a voltage drop and something that led to engine failure.

    Do you know why you had a voltage drop in the first place?

    What type of engine failure, what type of engine, and what RPM were you at when it failed?

    Well I tune it at dyno before a week clean of knocks.

    Yesterday I make a pull 4rth gear WOT, the alternator belt came off because was old at about 6000rpm (I saw it at logs) I keep WOT until 7500 then I left the throttle.

    Black smoke from exhaust, oil from vents.

    No lean afr spots no ignition changes.

    Dwell: 1zz coils 2.8 at 13.8v 3.2 at 12v

    Hello guys,

    I just see an advertisement with KnockLink G4 ( something like a shift light but for Knock )

    Is that so gorgeous as advertising says?

    Self calibration so you must no worry about gains, frequency, high RPM noise, fake knocks and stuff like that. 

    Is that really so good?

  18. 3sgte knock gain

    in G4+

    Posted

    Hello guys.

    Yesterday I was on dyno and i make some pulls.

    I realize that my knock global count was at 1000 (maxed out) from 6000rpm till 8000rpm.

    I have Cop setup 

    My gain is 1

    And my filter is 6hz

    Can I put 0 Gain value or -1 etc?

  21. Fuel Consumption

    in G4+

    Posted

    Ok. Can you help me to set it up?

    Fuel system type? My 3sgte have stock FP on fuel rail. It controlled through vacuum. So i choose MAP?

    Base fuel pressure? At 3s forums they said base FP is about 36psi-41psi. But i have bigger fuel pump, maybe this affects my FP?

    Fuel Charge Coolong Coeff? What is tje proper way to calculate this?

    Min Effective Pulse Width? I have PL-4 1000cc injectors i found the dead times through the site of RC but they dont have the MEPW. They dont responding to my emails.

    Hello, I found a topic here with a Davidv's experiment, and i want to do the same.


    But when i try to log my Inst. fuel consuption it shows only number 0. Am i make something wrong?
