Long term fuel trim

Postby z350tt » Sat Nov 04, 2017 3:43 am

I’m ready to turn on my long term fuel trim. Default settings in the provided z33 VE turbo file has +\- 8% correction and 6 sec as the trigger before making any changes. I don’t think I am ever that far off for that long. Is that as Low a correction trigger as I should be running? Just looking for a recommendation.

Also where can I see the long term trim being applied? I see the reset button on the setup page but didn’t see a new table show up on my list so I could see it.

Platinum pro plugin

Thanks

There is no table on these older systems. You get a LTFT for low middle and high and these are simply channels you can view.

I'm viewing the LFTFs now and O2 control %. Are these two values additive and does a value of a 1 represent the same amount of correction in each?

Yes. 1% is 1% of the fuel. It is additive to the short term.
