Inerceptor guage how is it? Is it accurate? Can i run a wideband with it cause i know it wont be to accurate with a/f just reading the voltage. Any input would be great. Looks like it would be decent to use with hp tuners. Intrested in it cause seems like good idea but scepitcal would be using it for a/f, tranny temp, timing basically

 

It's as accurate as your car's PCM is, but I'm sure there are exceptions to that (i.e. A/F). It also only displays transmission temp if your car is an auto.

 

question is how accurate is the pcm?

 

accurate enough to manage the combustion of your engine....accurate enough. The real question is if the refresh rate is adequate. I bet it'll fit your needs just fine, maybe you'll need a wideband.
