new to this stuff, i have the new pro link cable the one that screws into the mpvi3. how do i wire it to my aem 30-300? then how do i log with it. i have looked on hp tuners site. i cant find a clear answer to what i need to do. sorry to be so needie.
The wiring for the prolink to AEM will be in the instructions, pretty sure it’s the analog signal out off the wide band ( 2 wires ) .The logging of the wideband was a bit tricky in my case but under channels I had to add the AEM under external inputs I think then “ conform “ it to A/F ratio or Lambda .
Sorry for the vague answer but it was a while ago and I won’t be near my laptop till tomorrow arvo .
Hope this helps and if you have no luck I’ll look when I get home tomorrow.
Cheers Carl .
I can double check at my shop tomorrow but I was in the same boat not too long ago. You can google the prolink wiring diagram, and match the two signal wires to the signal wires of the aem gauge (in your instructions manual). Cannot remember colors off hand.
As far as data log, I believe it was add channel>engine>fuel>open/closed loop>oxygen sensors>wb eq ratio 1 [mixture ratio] on the scanner
Prolink black-aem brown
Prolink red or blue-aem white
thanks ppl
Ok so as an update if needed under channels > external inputs > mpv12 / 13 > prolink > mpv12 a/d input ( colour of wire ) .Then once channel is added right click on it and select “ transform “ ( not conform “ ����) into an oxygen sensor in which ever ratio you like .
Yes, you will choose the correct wire color and transform.
ok thanks that what i didnt do right
a i did do that the first time, it was or is working in the scanner, but in the grafting part its moving around but not plotting. and its not flowing in the charts. im just lost. sorry to be so needy. thanks sirAttachment 155289 here is my run file
