Corvette Style Cluster Needles Sweep? I was wondering how easy or complicated it would be to make the gauge needles in my 2002 Pontiac Trans Am to do like they do in a corvette when you start it up. I was always raised around corvettes but I was unable to afford a corvette so I obviously settled for the next best thing. Anyways, I always thought that the sweeping needles when you start a corvette up was awesome! And I'm kinda wanting to do that in my cluster, depending on how difficult it would be. If it's extremely complicated, I probably won't do it but if it's fairly easy, I might tackle it soon.
well if you have a battery thats about to go out you'll get the needle sweep, needle sweep is actually a warning of the battery going out on 4th gen f-bodies. typically firs becomes noticeable after the car sits over night. so you might want to mess with it.

Hmm, alright. I've never had it do that so I had no idea. Probably won't mess with it then.
Without being able to program the BCM, you would need to design and program a circuit that would that would feed the gauges the proper voltage to sweep the full range and back down. Then with the 99-02's the oil pressure is the only analog input, the rest is class 2 serial data. Its a cool feature but way way too much work for little gain.

Yeah, it sounds like way too much work. I was just curious. Like I said, I would only do it if it was a simple mod but it's way out of my league and seems kinda wasteful for such a little thing. I can live without it, just trying to compete with my dad, he has an 2008 Corvette, lol.

The BCM on 4th generation f-bodies has nothing to do with the instrument cluster other than managing a few of the warning lights (seat belt, security, etc.). So even if the BCM was programmable, you couldn't affect the gauge needles with it.

On the 99-02's all but the oil pressure and speedo are class 2 serial data though. But your are right, I did wrongly mention the BCM.
