Today , I was driving my 2003 350z, when this happened while driving. I am using a brand new Hitachi TB. but the Aux9/10 have been happening quite often and randomly recently.
AS you can see in the graph, not only the TP signal was affected but also the intake VVT soleniods. During the duration of the spikes, the AUX9/10 Supply stays at around 14V but once I let go off the Accel pedal, the Aux9/10 supply just slowly dive to 1.2V
The fact that both the intake VVT Solenoid and TP signal are affected makes me think this is a hardware internal to ECU. Once I shutdown and clear the codes, the ECU is acting normal, so it does not look like a permanent error.
Here is the log ( CSV format since I couldn't split logs, if you do know how to split logs and save them under the llg format, let me know! )
Throttle.zip
And here is my "tune"
latest.zip
What should I do ? I am thinking about reverting to the previous firmware before the latest update.
Thank you
The accel channels only work with the Thunder ECU which has built in accelerometers.
You should be able to use the gearshift control function to do the downshift blip. It will look at clutch switch and throttle position to determine if it is an upshift or downshift and apply the appropriate strategy from there.
Our 350Z base map has injector deadtimes and ignition dwell times for the stock injectors and coils. I have notes that the injector flowrate on our car was 284cc @ 345Kpa, which was the base fuel pressure. The fuel system type is returnless.
