It fooled me.
I doesn't seem to be working........or it'* reponse it is so slow now it'* almost useless.
When I first hooked it up, it swung back to 30 F (its zero point) so I thought it was good.
Then I took it for a long ride and it was warm but the gauge did not move above 90 F. Even with WOT runs to redline it would not move.
I was back on the phone with the Tech support.
Not only is that gauge obsolete, like they don't have any stock either, but they no longer produce any other sensor type air temp gauge.
He told me Autometer had not produced this gauge for two years.
I told him I had spoken to another Autometer tech in Jan/07 because the install instructions supplied had changed due to a recent model change revision that added an additional wire.
I asked him if he could refer me to their Engineering dept so they could give me instruction so I could tune the black box to the gauge myself.
I opened the old black box and there is complicated circuitry and three mini pots that look like they are adjustable.
The techie started his text book reply with.....that might be proprietary information....to which I cut him off cold with the fact it'* an obsolete part so that shouldn't matter and if Autometer was any kind of a reputable vendor...etc....
It'* still listed on their Internet site and I'll bet there are parts stores out there with a few on their shelf.
He left me on hold while he refered to a superior. When he came back on he became very accommodating, took my number and asked detailed questions.
I gave him the details of the vendor I purchased from with invoice number, date of purchase etc and he said he would get back to me.
