How to Display AFR ERROR Using HP Tuners VCM Suite 3.X Software

[@LegitStreetCars]

Can you do a video on this but using lambda? Great videos BTW

[@JJREKracing]

It's virtually the same thing. Just use commanded and actual lambda then use the %Err lambda math.

[@jameseaston1329]

thanks for all the 3.X tips. Any tips on how to change the commanded AFR for turbo application?

Great vid, please turn the mic up though!!! :o)

How do yo know that AFR ERR is going to use your wideband by default? I remember having to put the input's PID in the Function in earlier versions of VCM Scanner to tell the Graph from where to get the error.

[@TheTuningSchool]

The HP Tuners scanner knows that the MPV-I input you selected is linked to a wide band. It also knows commanded AFR if you have it selected in the Channels list. It just simply does the Math in the back ground and puts it in the table

[@cameronjohnson6321]

i have two widebands one on each side in there. What will it do then? How do I verify its using the wideband. Also, you guys are awesome. Thanks so much for making this!!!

[@Good-Enuff-Garage]

@@cameronjohnson6321 Did you ever figure this out, I would also like to monitor both banks with two Wideband sensors and would the AFR Error know to take the average of those two?

[@jw334]

Great Video But I cannot for the life of me figure out how to add AFR Commanded it simply is not in the drop down like you show in the video. My ecm is an E40 and maybe it doesn't have that ? What would I use in lieu of AFR Commanded if that's the case. I've been trying to get this to work for two weeks. Any helps is much appreciated

ME EITHER

What changes do I need to do this on a Ford? Using HP 3.2, I do not have the same parameters. I am assuming I select MAF volts, but how about the rest of the graph?

[@TheTuningSchool]

This video was made using a GM tune file, but the process is the same for Fords. You want to select the AFR Error Math as the parameter that will put information in the graph. Then set the row and column axis to directly reflect the table in table in the VCM Editor that is controlling the wide open throttle fueling for the Ford you are tuning. Then as long as you have AFR Commanded and a wide band in the main channels list everything will work as it should.

[@victunner1189]

The only AFR commanded I can pick is "equivalence Ratio Commanded". Should this work? When I play back the log I can see the high lighter cell in the graph moving , but no data. Thanks

[@raptor700yfz]

It it possible to make a afr error table like this for a mafless tuned vehicle?

[@Logicinfact]

raptor700yfz it would be nice if the Tuning School responded and showed how but then again, they are a tuning school. Can't give it all away...

[@JJREKracing]

Yes, depending on the computer, you would do the same thing and just use the VE table like he used the MAF table.

[@richbayer7523]

seems more like this is setting up a MAF error more than anything..

[@1987FX16]

Okay so you NEED to put "MAF TUNING" in the title...
