    That sounds like a load of crap so that's what im supposed to tell my customer after I told him yea hptuners will work on your truck no problem,so the operating system is not a problem its noise in the wiring?

    Sorry that's frustrating information David, you're definitely not the first to have trouble with this error message.  You may have misread the article though - it doesn't mean we can't work with the vehicle or PCM.  Have you tried working with a bench harness?

     

    Wish there was more we can do, but noise in the wiring in older vehicles is out of our control, and the best we can do is give advice on how to work around that.
