Problems tuning AutoVE

[stevedarman]

Can anyone help me?
When i am tuning as per the AutoVE tutorial The ben's always over compensates
eg. if i have a cell that shows 0.89 then next log will show it around 1.12 and this just goes on

There is a couple of spreadsheets floating around that
can manually adjust the percentage of BEN.

A calc.pid formula for 50% of BEN would look like this:
{BEN}-1.0)*0.5+1
This is the percentage to reduce or increase.
-50% =.5
+50% 1.5

Can you tell me where to find this spread sheet ?

[mr.prick]

Here it is.
5935
A calc.pid is easier tho.

I have just been looking at the cal.pids I can see where to put the equasion but dont know about the other numbers (slots and PRN )
do you have all the infomation i need to enter for the pid

[mr.prick]

This is for serial WBO2
Change {CALC.BEN1} to the BEN you are using.
*CLC-00-001
factor 0.0 1.4 0.2 "({CALC.BEN1}-1.0)*0.5+1"
================================================== ===
CALC.%BEN1 F001 CLC-00-001 factor Fuel "BEN 50%"

These numbers should match.
The next cal.pid in sequence will be F002 ect.
They don't have to be the numbers I post here but the must match and it's
easier to start with 001 then keep going. IMO
I have 30 calc.pids

When you say
"Change {CALC.BEN1} to the BEN you are using"
what do you mean?

[mr.prick]

Which BEN PID are you using?
Are you using serial WBO2 or analog?
If you are using serial you will change it to the BEN PID that matches your PCM.
Example for serial:
BEN Factor Bank 1, Serial Wideband, E38 style {CALC.BEN1_E38}
If you are using analog you will change it to the BEN PID that matches your WBO2.
Example for analog:
Base Efficiency Numerator 1 - LC-1 {CALC.BEN_LC11}
Or if you use a WBO2 that is not pre-defined by EFILive and
you have made your own BEN PID, use that one.

Ok i get it now I am using serial wideband lc-1 ls1 style
so i will use calc.ben1

[stevedarman]

Not quite there i have it all in but it shwoes as unsupported
it all looks to be ok must be some thing i have missed

[mr.prick]

{CALC.BEN1} will need to be selected for it to be valid.

[stevedarman]

Found it "({CALC.BEN1}-1.0)*0.5+1"
Needed to be *0.5+1
It is working now and the tune is dialing in easyer
Thanks for all your help and quick replies

It needs a number to the left of the decimal to work. :doh2:
I had it dividing by 2 to reduce BEN by 50%.
For future editing purposes it's a little easier to multiply. IMO

If you want xx% of BEN it would be *0.xx+1 ect.
If you want to increase BEN by xx% add 1 to the multiplier: *1.xx+1

[stevedarman]

This has made it a lot easyer now and it has dialed in quite well.
The tune seemed to be quite ok for the first couple of days, now it doesnt like to idle
can you sugest any causes i am runing with maf, closed loop, stft, and ltft turned on

Read thru the Idle tuning link in my sig.
