  1. need more D. Ive had hell with some LS based throttle bodies. The increase in derivative gain will help dampen the oscillations.
  2. Has the ecu been appropriately tuned?
  3. @Khaled Abdurhman What vehicle do you have? Some vehicles tps is only an idle switch and wot switch, for example early model MX5 miatas.

    Unlock Code

    But when you input the serial number into the link code generating page it asks you to leave off preceding zeros
  5. what fuel mode are you currently running it in? What is the injector scalar or master fuel value at?
  6. How high are you reving the engine? If only going to 7-7500 rpms, then you should be fine. But if your winding it out to 8-9k then you may have some concern. You typically want roughly 10psi for every 1000 rpm. Ive built many subaru engines. Most would be around .001 on the mains and .0015-.0018 on the rods. Did you reuse the oil pump from the first motor? Did you inspect the internals of the oil pump?
  7. Why not just start your tuning with the new large injectors and not have to worry about the change once youre ready for the power tuning?
  8. Any ecu can delete the IACV without going drive by wire. You simply set the idle speed with an idle throttle stop so that zero throttle is you set idle. You can do this with the cable but I would recommend adjusting the closed stop on the throttle body(ies).

    I/O Expansions?

    will need to verify your voltage values in the analogue tab of the runtime values page. Then verify that they are registering as cruise functions in the ethrottle tab of runtime values page.

    I/O Expansions?

    The way the logic works in the software is just like any modern car. There is an on/off button, set/decel button, resume/accel button, cancel button, and brake switch. It works very well and i have implemented this into several cars using the AN volt and DI method, really just depends what inputs you have available.
  11. when you turn the ecu off the injector drives are going to ground.
  12. Car im working with, im going to attempt to use the ABS system in a standalone application with the G4+ xtreme talking to it over can for wheel speeds.
  13. @Adamw would it be possible to use a spare aux out to control the relay for the ABS system with a gp out that controls the relay with engine run time >= x seconds? Also could you email me the 350z doc youre talking about? burnettbrad84@gmail.com
  14. If this is a plug in unit, i would stick the stock ecu back in and see if there is any change. May be easier to diag the abs fault with the stock ecu present. Im very interested in the outcome here as im busy with a rather standalone build with the 350z abs system.
  15. Just also be sure to double check all you I/O to verify everything is in the correct place. I recommend disconnecting all your loads while making config changes.
  16. I had this conversation with a link tech guy yesterday. I have attached the 12v supply for the lsu 4.9 to the link power supply on the A connector.
  17. It will still get you in the ball park. Yes you will have to adjust some ignition parameters and change some settings for the vvt, but it will be a good starting point.
  18. there is a 2jzgte base calibration in the software. Maybe start there?
  19. didnt even think about that. But that is perfect.
  20. then test it out with normal and 2500 and see how far that gets you.
  21. go to starter control in the chassis and body tab. change starter switch mode to normal and deactivation to 4500rpm The starter button or switch should then act like a normal system where you have to hold it till it starts.
  22. the kick back is from the combustion event happening while the piston is still on the way up the bore. with the negative timing it will happen after it passes tdc so the combustion event will help push the piston down the bore.
  23. I have fought this kind of cranking issue with single and 2 cylinder motors. The compression on cranking really messes with the ecu's ability to accurately read the triggers, clearly. I have always remedied this with very low if not negative timing in the 0-250 rpm and low TP area of the ignition map. It would be nice if link could add a cranking timing setting in the main ignition settings but considering that is not there, you have to do it in the main table. As Race Jase in the other thread said, he damaged starters and Bendixes due to kick back. The low to negative timing values fixed that for me as i even sheared teeth off the flywheel as well.
  24. I have had inconsistent results with changing map sensors. Switching between oem sensors i have had odd offsets and tune has needed adjustment to compensate. I would recommend at least a double check before just calling it good when changing anything sensor related.

    CAN Hub

    If you can bus wiring between the ecu and the CAN lambda unit is short, you can get away without the termination resistor.
