can an interceptor tell me the air fuel ratio on my lsj or no and what is it best used for just wondering might buy one.

 

Yes and No

No: That feature is not supported on the LSJ, to be read from the Dataport

Yes: You can by a kit, and wire the kit upto one of the Analog inputs to the interceptor and get it work that way though. (My next mod)

I do reccomend the gauge: I baughta dual setup, put them in the ZZP Tripple Piller pod, and I LOVE It...

 

Yeah, I have the ZZP triple gauge pillar and I use the AEM/UEGO wideband separately from the Interceptor.
