V3.0 NGK WB AFR Error works fine... with AEM 30-0300 CAN... it doesnt

[10_SS]

Is there something else I should be doing to get the AFR Error working with the AEM 30-0300 CAN update? I had AFR Error working fine with the NGK AFX, now swapped that out with the AEM 30-0300 over CAN, and I get mostly 26% error in all cells... seems to be working at WOT.. but not in closed loop.

Confused...

OMG AEM SUCKS!! rawr rawr rawr.

Now that that's out of the way...

What's your channel list look like? Do you still have the old transform there for the NGK WB?

dang, I removed the analog input on the channels list once but somehow it was still there... maybe I had two Scanners open... huh. Im sure it will work now, thanks

[schpenxel]

Maybe!

Welp, nope... I scanned with just the AEM in the channels and now I just get no value in the AFR Error Graphs... anything with AFR Error now shows no value, but the cell moves around like it should.. Its like the AEM Can value isnt making into the Maths for AFR Err? Is that possible?

[schpenxel]

Can you post a log real quick?

yessir... thanks for all the help

Add commanded EQ ratio to what you're logging and then use EQ Ratio Error instead of AFR Error and it should work (if you aren't already using EQ Ratio error, I didn't look at your config).

Basically AFR error needs commanded AFR and wideband AFR. You have commanded AFR but no wideband AFR, so that one doesn't work. Then there's EQ Ratio error which needs commanded EQ ratio and wideband lambda. You have wideband lambda but no commanded EQ.

So.. try adding commanded EQ to your list of channels and I think it'll work then

I added EQ Ratio, but still dont work.

Post a log with that one added, I'll take a look in the morning and see what I can figure out

I went back and updated the graphs to EQ Ratio instead of AFR Err and it works... so thanks you fixed it

[schpenxel]

Good deal, I was hoping that would fix it
