AFR Spikes (2JZ-GTE)

Post by SSC_Master » Fri Jan 12, 2018 10:15 pm

Hi mates,

Actually I’m trying to find some good settings that the AFR values follows the AFR target table.
I’m 70% happy with the result. When I push the pedal the values reflects what’s written in the table.

My problem are these spikes at the begin and at the end of an acceleration sequence. (see pictures)
Have you any ideas which parameter I have to adapt in the EGO Feedback section to erase these spikes ?

That's going to be in the Enrichment settings - check the log for your Enrichment's

Thank you very much for your answer.
I very appreciate it. Because it is new for me it’s
not so easy to see the influence of the different aspects.

Is it right to adapt the parameter to eliminate the first spike in the section (picture first spike) and for the second spike (picture second spike) ?

Yours sincerely
