have any of you ever seen this external signal harness for the emanage blue? According to mohdparts.com it can be used to display AFR. It looks like you have to tap into your wideband and it will display the reading on the profec. Anyone have any thought on if this would work w/ a zeitronix wideband?

Here is the diagram

 

There is also this:

E-manage Air/Fuel input Harness - #15900912 ONLY $25*
This harness is used to feed the air/fuel signal from your wideband brain to the e-manage.
Will work with e-manage upgrade v1.25/1.47 or 1.25a/1.48

Can someone explain which one i would need to read the AFR from my zeitronix on my profec e01

 

Ok i think i figured it out after reading through the manuals. The first harness i posted is used to display any input device of your choice( in my case i am using my wbo2). In the profec you enter the voltage range which is 0-5v and the enter the high/low values which would be 9.5-21. It looks as though the profec takes a ratio of the voltage seen and then displays the #value that corresponds to the ratio.

The second harness i posted is used to datalog AFR w/ the support tool.

I must say it is amazing what you can do w/ this thing. It pretty much eliminates the need for my guage now. For the $450 i paid for this, the profec seems to be one of the best bang for the buck as far as boost controlers

 

Yeah just be careful with the WB though. If it's like the EU, it will want a linear 0-5v signal from the WB, which the Zietronix is not.

 

how can i find out if the blue requires a linear voltage? I looked all over on mohdparts.com and couldn't find anything.

 

I thought you said you wanted to hook the WB up to the Profec...

Anything in the manual?

 

thats right, all i want is for the readout on the profec. I looked in the manual but it didn't say anything about a linear voltage requirement.

I accidntally reffered to the blue. I meant the profec

 

Actually, reading your post above again... (#3) and looking at the manual I believe the profec wants a linear signal. So the Zeitronix would not be a great choice.
