The image attached shows the a/f graph in the emanage. the connection is to an AEM wideband. The input is 0-5 volts and the graph has time on the bottom and I think throttle on the left. I could be wrong as I am not all that good with this yet. My question is how do I get the graph to display actual afr numbers and if it cant how can I convert the data to actual afr numbers?

 

thats your datalogger.....your afr will be in the form of a graph as well as everything else you have selected

 

it will show actual afr like the gauge would? I have not used it yet. please explain this graph to me if you could.

 

in order for you to get it to see numbers you have to run the datalogger and then save it as a .txt file.

 

What the left set of #s that start at 0.0 and end at 99.9? afr on a guage is like 9-16 so why would this go up to 99.9? I think I need the complete idiots guide to understanding this graph. When the data is put on this graph how can I see it in terms of #s like the gauge would show between 9-16?

 

Can someone please explain this to me and help out a new guy.

 

on the left is just a number graph....the reason it goes that high is becaue your also datalogging fuel trims and what not...your afr gauge shouldnt go above say 20 numerically.....bottom is time.....like i said...just start your datalog when your tuning and then stop after a pull.....save the file as say "1.txt"....then open the file in microsoft excel and review.

 

Did you hook up your WB to the Emanage properly? Have you set the scale so the Emanage knows that 0v = 10:1 and 20v = 20:1 AFR? You have all the conversions on the AEM manual.

 

i didnt have to set voltage on mine...just a scale from minimum afr to max

 

Was asking OP - not you :p

 

regardless if you were asking the op your not.....you dont have to set voltage if you have the uego.

 

The aem is in but the bung needs to be welded on (today or tomorrow) then I will see the data. I would have been easier to read if the graph could display the afr range of the gauge without all the unused range 17-99. I guess I can make more sense out of this once I see the data. As far as setting the range im not sure when you select a/f option in the emanage I would choose other then what is the next two boxes? The output from the gauge is 0-5v just like the emanage wants so im assuming thats ok but what is the boxes for? Seems like they effect the time line on the bottom, is that what its for?

 

It's not setting a voltage - the voltages are there. It's telling the emanage what voltage = what AFR. And you do that as you had said - by setting min and max AFR.
