Misfires at engine loads above base tables
I?m getting misfires here and there (found via logging not picked up by cel) with loads greater than base tables but less than optimum, like 185 190.
On other cars I?ve helped tune these haven?t come up even with loads beyond optimum tables.
They show up on random cylinders. I have about 20k miles on oem mb sparks. I haven?t upped inj pulse and similar but have increase fuel rail pressure to 20.55 and fueling under power enrichment and component protection.
