Started AutoVE Tuning help!

[jeff keyuk]

Hi Guys I have started auto VE tuning, Please take a look to see if I am on the wright track,I am using a Fast WB,and I have done everthing the tutorial say's to do,.

Your throttle is not sufficiently steady, the transient filter "Base Efficiency Numerator" is throwing out all the data.

Also, you need to set your LM1 to 1/6 filtering to smooth out the measured AFR;

the measured AFR is tending to be rich.

[jeff keyuk]

Hi Joe! Thanks for the answer back, I will be more steady with the throttle,Question on the Base Efficiency numerator,In on the map properties,I click on to (Base Efficiency Num.1-LM (factor)-not currently selected). I take it that is wrong,Which one is the one I should of click on to!And in the Data filter 5.00% is to high, As you can tell, I new to this. Thanks again for any help.Cheers Jeff.

Hi Jeff,

No worries... post a screenshot of the filter you see...

[jeff keyuk]

Hi Joe Not sure how to do a screen shot,but this is what I am looking at in the "Data Filter"
NAME ( TPS MOVES TOO FAST OR LOW COOLANT TEMP)
FILTER CONTROL: (Exclude date Frames) and I think that should be [U](Include date Frame )
and in the FILTER TYPE is ( Changeing mor than 5:00% per 100ms.)
than I have inthe Filter (Sae.ECT)is changing more than 66.80degrees C.per 100ms.
Hope this is ok what I just posted to you. I will try and do that screen shot.Thanks again jeffkeyuk@live.ca

Find the filter that looks like this:


13680



if it has a condition for RPM < 2500, delete that condition (highlight it, click Remove, click Ok).

[jeff keyuk]

Hi Joe, No luck trying to screen shot my filter data. The printscreen tab seem to not work on my key board???? I have the image editor greenshot,Question Can't you just click on Log file up top to see the filter data Log_jeff keyuk_autoVEtune8 on the first page and see it there.

[joecar]

When Greenshot is installed it intercepts the PrtScrn key-press and captures the screen (you have to mark a rectangle on the screen using the cross-hairs).

[joecar]

Your filter may not look like mine... (the filter is not stored in the log file).

Hi Joe! Is this what you need to see! Jeff

Hi joe. Is this ok! and did you get my PM .Talk to you later

[joecar]

OK, that's the wrong filter...

in Name select Base Efficiency Numerator (SAE.TP)

and if it contains a iine mentioning RPM < 2500, delete this line.

Hi Joe This is the one.jeff
The line with RPM<2500 I just removed it ??? in the data filter!

[joecar]

Yes, just like that;


click Ok to close that box.

[jeff keyuk]

Hi Joe! Ive click ok on the box,2- question! I will go right out, & start logging data and come back to see how it is and second what about the Rich condition in on the car ???

[joecar]

The log will show you how rich, then when we apply the maps it will be corrected.

[jeff keyuk]

Thanks joe! Have to wait till tomorrow,weather is bad here,finally we have rain,I will do a logging data on sat.am,post it for you to see. I never told you what I have change on the car, New 215ETP Heads,Street sweeper cam,228/232 612/600lift 112+2*advance. Fast intake92mm,90TB,underdrive pulley,Might have to much injector for it FMS-M-9593-M39,???? Long tube Headers,high Flow cats.SLP85mm Mass air,MSD coils ,vera air ram,ect, My plan is get a handle on the motor, This winter I am installing new RPM Trans,upgrade the rear end,and so on.And again thanks for all your help,and to all the guys on the EFI Form.Talk to on sat.cheers!

came back to see the file,car very rich! Went to apply filter and this message came up !
Check pid list for what it was asking for ,could not find.??????
So What am I doing or have done wright. Thanks jeff

Base Efficiency Numerator (SAE.TP)
references unselected Pid:GM,FTC
Filler will not be applied.

[jeff keyuk]

I work it out,I thought it was in the pid list,it was in the data filter,made two logs,sure seams to make change slow!!!!!Is that normal !

need a little help! with data Filter !

[joecar]

Something is wrong with that map...

[macca33]

Jeff, this attachment depicts what your map and filter should look like (see attachment). Ignore the metric measurements and you can see that I've only chosen the two filters. My BEN map is set up to show values in thousandths (3 decimal places), I think the deffault EFILive set up is in hundredths (2 decimal places)

Filters are set up to:-

- EXCLUDE TP changing more than 5% in 100ms; OR,

- EXCLUDE engine coolant temp below 85 degC.

So for you Imperial measurement people, the first one would be the same, but the second may be the 176 degF you have in your current filter.

For basic AutoVE determination, those are the only two you need. You can include other exclusions / inclusions in the filter once you've got the hang of it and you wish to get the most accurate result you can achieve.

If you go through the tutorial, you'll get it fairly quickly.
