  1. Attach a log and the latest tune and I can look at the other stuff.
  2. I would say mostly it is the idle control gains too high. Try these changes in orange: I would also give the idle ignition control more authority as E-throttle is too slow to compensate for sudden changes in RPM/Torque. Something like this would be more typical: I would also increase the idle control MAP lockout to about 65Kpa and update to the latest firmware as 5.6.8 had several CL idle improvements. There may still be other factors contributing but they will be easier to see when the big oscillation is gone.
  3. I dont think so, The ecu cant fire injectors or spark if it doesnt know crank position and speed. If you want any further help you will have to attach the tune and a PC log.

    Attach a copy of your tune. What ECU? Was the WB1 purchased recently? Have you swapped the CANH/L wires at the ECU end of the adapter cable?
  5. Flex fuel is never going to work well with your current map, traditional fuel equation results in a lot of compromises with blended fuel. Using multi-point injection mode is also a big compromise as the injection events arent timed to valve events. You really need to start from scratch using modelled multi-fuel equation and sequential injection mode.
  6. Why do you suspect the trigger? If idle speed is high then it has too much air, this would typically mean the idle valve is too far open, the throttle blade is too far open, or there is an air leak. Attach a copy of your tune and a PC log may get you more specific advice.

    ECU Error Code 70

    If you copy the idle control settings out of our 350Z base map it will likely behave a bit better. The basemap has closed loop idle enabled and idle ignition control which helps a lot with E-throttle engines.

    Link G4x boot mode

    Usually boot mode means the ecu doesnt have power on the correct pin, so is only powered up via a back feed. The most common cause of this with a Nissan plug-in is the connector is not seated properly. Undo the bolt in the middle, and reseat the connector again, making sure to wiggle the outer ends on the plug home as you tighten the bolt.

    ECU Error Code 70

    The TPS hasnt been calibrated or you didnt store after doing a calibration. So the error is from the throttle hitting the mechanical stop before reaching the commanded position. TPS main and sub should show very similar values when calibrated. Put the min clamp back to -95 before doing the cal.
  10. Yeah stick to post turbine, especially with NTK sensors, they are about 4x more pressure sensitive than a LSU.
  11. Change the CAN mode to the alternative AUDM/JDM option.

    Idle steps issue evo

    The base position table in the G4+ is "steps from fully open" so smaller values means more air. You should have smaller values at the colder end of your base position table. At power off the the idle valve will do a reset, then park at "home" (50 steps from fully open) so the ECU knows where it is at next power up. At power up the idle valve will then move to "base position - start up step" while honoring the min and max clamps.
  13. I notice in one of your pulls when the diff fuel press takes a big dive there is an increase in batt voltage about the same time. No auxes turn off at that point so those events are possibly related. Pump sucking air? Lose connection? You could do a similar static test with FPR pressurised and measure voltage at the pump to confirm how much volt drop you have in the pump supply. Your batt voltage reported by the ECU is quite a bit lower than typical at about 13.0V where as that should be more like 13.8-14.5 so that is not as good as it should be which will be contributing but I dont think is your main issue. For some extra safety in the meantime you could set up a 5D fuel table like below so the a drop in fuel pressure is compensated with increased inj PW.
  14. I have PM'd you.
