AD filtering question?

[67SS509]

In the V2 control interface under AD filters what do the numbers 0 thru 5 represent. Sample rate? Damping? Where is the info on this in the user's manual. I couldn't find anything.

I have been working for several days trying to get the AFR readout on the dashboard to read correct. It is always 1.1 to 1.2 AFR higher than the actual but it is steady now. I'm baseing this on 3 things while running in closed loop...(1)Afr reading from the FJO to the laptop thru serial cable...(2)the narrowband sensors controlling to 14.63 and watching the L-trims...(3)sight, sound and smell for richness or lean and how the engine idles and responds to air- rpm picks up when rich and you add air.

I have went thru the calibration process and without the engine running everything is correct. Tried altering the expression to make it read 1 AFR lower but that didn't work either.

AFR will float no matter what until you go WOT
then AFR should be at it's steadiest.
In CL AFR will float +/-1AFR that is what the NBO2s do,
AFR will never be solid like commanded AFR is.
In my experience it can be difficult to distinguish rich/lean by smell.

If adding/subtracting the offset in the sae_generic.txt or your calc_pids.txt
does not change things then check to see if the analog ground gives 1volt.

I don't know how the ADFILTER in the V2 works or what setting is best.
I think the FJO can be used with serial connection, have you looked into that?

The AD filter number is the number (n) of samples used to average/smooth the AD signal...

n = 0, 1: no averaging.
n >= 2: averaging over n samples.

This isn't in the user manual yet.

A lot of things are not in the manual right not. :hihi:
What is n, can that be defined by the user?

[joecar]

Yes, go into V2's setup option screen.

I have all the grounds tied together. My FJO does not have a dedicated anolog ground. You would think with my FJO setup to give 0v-5v=10AFR-20AFR then this expression would take care of my problem...
AFR=V*2+9 instead of AFR=V*2+10

My FJO uses a serial cable connected to my laptop and works with the FJO software installed. Reading the AFR this way seems to be very accurate but does not give the feature of using the BEN map in EFIlive. How can this be introduced into EFIlive? I don't see a serial port on the V2 interface. What am I not grasping here?

[mr.prick]

It is the jack next to the USB 1.0 port.
You will most likely need a null modem not a gender bender with
the RS-232 cable that came with the V2 and you won't be able to use the FJO
software for logging. (no big deal)

Analog is a bit slower and not as consistent as serial with my LC-1 so don't feel bad.
If the V2 reads a reliable voltage supply properly then the ADs don't need calibration.
Can you change the response time of the FJO?

With serial cable, you log the serial AFR pid WO2AFR1...

the serial BEN is BEN1...

you have to copy one of the analog BEN maps and edit it to use BEN1, and save the map with a new name... you will now have a serial BEN map.

A null-modem adapter is different than a gender bender.

Looks like I had my next question answered before I asked it:cheers:

True, I have never seen a null modem adaptor walking in Kings Cross.

The serial cable from my FJO has an end the same as the Flashscan cable. Does that mean I need a "gender bender" adapter?

[joecar]

Yes, probably... does your user manual show a pinout for the serial cable...?

[mr.prick]

Here is the V2 serial cable diagram,
it's for the LC-1 but you can use it to match the FJO.

OK. Got the serial connection made today. I'm not sure if the BEN map is correct and I have the correct Pid's working. On the BEN map I was getting numbers like 1.70 but it would follow MAP and RPM.

Also did a little more work on trying to make the AFR read correctly on the dashboard thru the analog. The calc.pid seems to have no effect on it. I can substract 10 from the expression and the AFR readout stays the same. Wonder what has gone wrong there. The analog AFR has worked good for several years until a couple weeks ago when I had to replace a failed sensor.

[67SS509]

This is my calc_pid

[mr.prick]

Try this just for the hellofit
"({EXT.AD1}*2)+10"
For serial you need to change the V2's internal settings and,
use the serial WBO2 PIDs.
For the FJO it has GEN2 & GEN3, is yours a GEN1?

I tried it both ways already...with and without the brackets...there was no difference.

Searched but could not find where in the V2 for the external signal. Is it supposed to be under setup?

I believe my FJO is the GEN2.

I'll have to get it off my laptop to post the PID's I'm using and the MAP.

[mr.prick]

F4> F1> F1> scroll down to WBO2 Type
PIDs you need to select:
EXT.WO2AFR1
EXT.WO2ST1
CALC.BEN1
Then of course change your maps properties to match the EXT.WBO2 PIDs

[67SS509]

OK, was missing the scroll down past AD filter...thanks. I'll try it again tomorrow.

Is the calc_pid used by EFIlive when you are doing the serial input?

[joecar]

If you're using serial AFR, then you do not need the analog afr pid in your calc_pids.txt file...

Do what mr.prick said (enable the serial pids in V2 setup options, select the same in the scantool, create a BEN1 map).

[67SS509]

I think right now what I have left to get right is in the V2 internal settings. Mine doesn't have a choice for GEN2 or GEN3. It just has FJO. Got to spend some more time in the V2 settings.

Here is a short log so my MAP and PIDS can be viewed. I think they are right but would appreciate someone verifying them.

[joecar]

You need to enable the serial AFR pids in the V2 option setup screen;

Then in the scantool:
- unselect EXT.AD, CALC.AFR_FJO11, CALC.BEN_FJO11;
- select EXT.WO2AFR1, CALC.BEN1;
- take any BEN map, edit the Data tab to use CALC.BEN1, save with filename "{B0101} Main VE - serial WO2 BEN.map";
- on Dash tab, in charts/gauges, delete CALC.AFR_FJO11 and CALC.BEN_FJO11, and instead use EXT.WO2AFR1 and CALC.BEN1.

Pretty sure I have the MAP and dashpage set up correctly now. I followed the tutorial for setting the V2. I got down to >Display W02 and got the "Controller Not Found", cranked the engine and connected. The V2 still displayed "Controller Not Found" and the second LED was blinking. W01AFR1 on the dashpage stayed at 25.00 (commanded AFR 13.63) and the BEN map stayed at 1.73 but did follow MAP and RPM ok.

Something is still off in the V2 settings, any thoughts on what's wrong. Do you have to do the "Black Box Logging" portion of the tutorial just for pass thru logging?

Hang in here with me guys...I'm getting close and I do appreciate the help!

How did you connect your wideband to your V2...?

Was the wideband powered up...?

Used the Null Modem connector. Verified the ground lead thru the connector and the colors matched for the Tx lead and Rx lead so I'm fairly sure it's correct. Wideband was powered up.
