Should be the white wire.
All my other AEM's were the white wire. |
Great, thanks
|
So, in conclusion: read the very first response for every answer in the thread.
|
Bumping an old one, but was this for a nnbs pcm? Im wanting to do the same
|
Yep, NNBS ECM. E38. |
10-4. I found a wiring diagram and it shows pin 55 being not used. Does something need to be activated in the ecm for hptuners to see this input?
|
I wasn't able to get this to work.. pin 55 on E38, 2008 Silverado RCSB. No data in hptuners
|
Wouldn’t be easier just to get a wideband with a serial out to plug it into your USB port on your laptop. If your using standard HP tuner |
Or the OB2 wideband that AEM sells.
Haven't tried the EGR trick on the E38's, only the P01/P59 have I done it before. |
The OBD2 wideband only works on newer Can based ecms. Like 07-08 up |
