APH

Sensor failed. 3d Trim could work but not ideal, temporary suspend fuel trim and return to open loop will be easier to diagnose issue. Unreasonable fuel trim may not be a lambda sensor issue, it could be a tps/map sensor issue.

The total size of the log file is 33mb, even compress is 13mb.. Is there way i can reduce the data and export to .llgx file?

Here is a log of a Lambda sensor issue where no fault has been flag, where Lambda 3-4 while its driving and Lambda Trim just stay at max at all time. I suggest adding Lambda Trim Max/min fault could resolve few lambda sensor fault issue if fault unable to define. This is a LinkG4X Fury using internal Lambda. lambdaissue.csv

Some of the tunes we do are using full closed loop at all time. I wonder if requesting of Closed Loop Lambda Trim to be disable when Lambda fault on? This apply to all LinkG4X external or internal Lambda. Thanks, Brian

Adam, Thanks, for quick reply we will order the external e-throttle controller. Brian

I am a little confuse by how the manual document for e-throttle setup. So do i need external e-throttle controller or not? Thanks, Brian

2nd or 3rd only able to use a input sources, unless i use a math block (What are the way to use math block?) When anti lag status on with e-throttle target table set 0% APS and TPS is 20%. So When ALT status 1, APS reach 1%, over-run fuel function kick in and perform 100% fuel cut. I thought that is Integral Min clamp, if that is case it should call max/min duty? E-throtte idling PID doesn't perform integral negative clamp if i set the idle base position table to higher than actual.

1- There are no real way to have by pass air table for ALS using E-Throttle. 2- During ALS enable with overrun fuel still active. (E-throttle) 3- E-Throttle idling (idle actuator) Min clamp cannot input a negative value. (only add) Thanks

Thanks for quick response. Its all good now.

I am getting a error of TPS (main) (sub) tracking error. APP and TPS calibration preform successfully in setup mode, soon as switch to On mode i get this error. Thanks, Brian
