tuning e67

[MECHAN12]

i have read the how to tune made by swingtan and it is a good one , but i want to do the tuning in lamba and eq so that being said. i think my pids should be commanded eq
wide band lamba instead of commanded afr and wide band afr.
it that is so what other info should i read before i start this.. so i know what to do
thanks for the help

Your BEN correction factor will now be (commanded eq) * (wideband lambda).

See the attached calc_pids.txt as an example (serial wideband).

All else is same as Swingtan's tutorial.

Oh, I should have also said this:

copy that calc_pids.txt file to this folder: My Documents\EFILive\V7.5\User Configuration

and then start the scantool, goto the PIDs tab, click on the Parameter column heading (to sort on this col) and look down that col, you will see the pid CALC.WO2BEN;

that pid requires that GM.EQIVRATIO be selected; let me know if this pid doesn't work on the E67 (it should).

ok nether of the pids calc.wo2ben or gm.eqivatio work they are not for a e67 it says has red cross through them

Ok, it seems E67 uses E67.AFRATIO, use this instead of GM.EQIVRATIO.

On your V2, use S&T enable automatic logging of serial/digital pids (i.e. EXT.WO2AFR)...

In the calc_pids.txt your BEN would be EXT.WO2AFR / E67.AFRATIO.

ok joe i went into the calc_pids.txt and changed it to EXT.WO2AFR / E67.AFRATIO but i noi matter where i look on the v2 can i find enable automatic logging
thanks for you help and i know it is hard to belive lol but i an't all the time this dumb
