So I got installed my EU yesterday and I was trying to get it to work properly but the auto tune feature does not adjust anything at all. I'm 90% sure I have it set up correctly but I can email the setting and a wot run file if someone was willing to take a look at it.

If I select the map trace feature I can see the different cells jumping around however there are no adjustments whatsoever. The AFR readings is there and properly connected too.

 

Is it on duty cycle?

 

Yup check this it is a must. Auto tune will not work if injectors PW is set to duration.

 

This is not the same problem but may be related. When viewing a log either saved or instantaneous, the injector input and output pulse widths are always displayed as being the same, even though I know they are different.

Is this something that only works when the EU is in duty cycle mode as well?

 

^ you can log the in/out in either mode (as milliseconds or percentage), doesn't matter if you're controlling them via DC or duration - mine show up with identical in/out numbers both while tuning and/or logging in DC or duration. I don't understand why it's the same number, though.

 

Mine does NOT show up the same.

 

Kevlo, I think he needs to do the same setup I had before.

 

My in and out % for injectors are different. They should only be the same if no modifications have been done. Once you alter the injectors there should be a difference showing. Autotune doesn't work in Duration just Duty Cycle. Kinda stupid but ohh well...

Though its weird that DandyMax mentions the autotune when he's doing his map in pulse width/recommends it (I can't remember if he said it won't work in duration though)

 

Got it guys, thanks so much!
I was really frustrated because of this. Changing it to duty cycle worked.

However Input and Output is not the same for me AS LONG as it is positive change = ADDING duration. I added the adjustment map on the logger just to see whether autotune was working or not. And it tracks positive change perfectly and notes it too, but NEGATIVE change on the adjustment map shows as a 40% positive adjustment. Really weird

 

Yeah, that's what I'm saying. The number are always the same. My WBO2 confirms that the mixture is changing, but the numbers are the same. Guess the software is a bit buggy.

 

Understatement of the year.

 

Lol on half of the dialog boxes, greddy spelled "cancel" wrong
