VE table done now what.

[joecar]

For CLSD you can just enable trimming B3801 and closed loop B4205 (copy those into the new file).

High lighted are the things I think should be copied over to update my tune on the previous 1 bar tune( in red)

So I just need confermation that the stuff below in red is what I need to change to update my 1 bar tune to the new 2bar clsd tune. Is this correct? thanks in advance.

I think some portion of your VE is not filled in with current data (where it dips down)...

on ve i couldn't get an cell above 4000 rpm under 100kpa so I just kinda scaled it up...

[lstruck]

Fix these:

how do i fix that set them to like 90% 95%?

[lstruck]

I hope you set the cells in B3647 and B3649 to values other than stoich (EQR 1.00) during tuning...

if you didn't, then the COS would have trimmed using STFT when running on these cells.

Even if i had STFT and LTFT set to disabled?


So does this mean i need to redo my ve table?

[joecar]

Yes, all the COS's will do semi-open loop (STFT trimming on stoich cells) regardless of LTFT and/or STFT being disabled...

this means that the PCM was correcting ahead of you (so your wideband shows that no correction is required).

Yes, you will have to redo your VE table.

[joecar]

BTW: your COS has no STFT disable.

[lstruck]

they were when I logged I just changed it to try to finish it up...damn I've spent like 100 buck just on fuel for the ve tuning lol..

So can I just change all the ones in tables B3647 and B3649 to 1.01 or .99 or does it have to be like .90 or 1.10 ?

[joecar]

1.01 and 0.99 are fine.

You should be able to get most of the useable VE table in a 20 minute drive...
