Panos MZR Posted July 24, 2020 Report Share Posted July 24, 2020 ***WRONG SECTION*** IS G4X Hello, I have installed a silvia g4x plugin on an s13 and I have an issue were it cuts out at around 5000-6000rpm. I don't see reaching any limiter. When I progressively depress the throttle it goes all the way to the redline(7500) . I'm attaching some logs. Tried trigger filtering but still does it.

Adamw Posted July 24, 2020 Report Share Posted July 24, 2020 Two of your logs just show 1 second of idling, the other is just a free rev. Can you do a log of the actual problem occurring. Is the boost controlling ok? There are 4 counts of boost limit being hit in the saved statistics with a max MAP of 286kpa being achieved.

Panos MZR Posted July 25, 2020 Author Report Share Posted July 25, 2020 is on wastegate pressure which is rated at 10 psi. Also map limit is at 210 kpa. pretty weird. will make another log with it occuring on monday Quote Link to comment Share on other sites More sharing options...

Vaughan Posted July 27, 2020 Report Share Posted July 27, 2020 First up you are running very lean based on your Lambda 1 reading and it looks like it is missing at around 5000 rpm on the full throttle log as the lambda oscillates between ~1.2 and ~0.8. I would start by fixing your fueling as unless the lambda cal is wrong it looks like it could be causing problems. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 27, 2020 Report Share Posted July 27, 2020 Agree with Vaughan that it looks like the fuel table needs some work, even in the "progressive" log Lambda is ~1.2. But I would say your symptoms suggest you may have a lack of ignition energy. You may be able to try closing the spark plug gap or a little more dwell depending on what coils you have. Your batt voltage is quite high so dwell is quite low. Quote Link to comment Share on other sites More sharing options...
