Addicted To Boost Posted June 20, 2007 Report Share Posted June 20, 2007 I'm looking to get my gauge cluster working properly, like all of our Turbo clusters, the tach and speedo needles are off quite a bit. I looked at a sticker on the bottom of my gauge cluster and contacted them- the company said they'd recalibrate it, but it will cost a lot, even though it appears the cluster has been repaired there before. Does anyone here know how to recalibrate clusters or know of a place that can get the job done fairly cheaply? Quote Link to comment Share on other sites More sharing options...

Dark Ride Posted June 21, 2007 Report Share Posted June 21, 2007 Gnat did, and he explained it very well in a thread a long time ago. But since the search feature is so very helpful, I'll see if I can look through my previous posts and find that thread. Quote Link to comment Share on other sites More sharing options...
Dark Ride Posted June 21, 2007 Report Share Posted June 21, 2007 It took me a half hour, but I found it: http://www.w-body.com/forum/index.php/topic,54295.msg667051.html#msg667051 Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 21, 2007 Report Share Posted June 21, 2007 It took me a half hour, but I found it: http://www.w-body.com/forum/index.php/topic,54295.msg667051.html#msg667051 +1 for spending 30min finding that. So, that was a pretty good thread. What would be really neat is we could find out a way to put the right resistor in, instead of guess and check. But, I guess anything is better than having a wrong speedo. Mine reads ~5% fast currently. Quote Link to comment Share on other sites More sharing options...
Addicted2bass Posted June 24, 2007 Report Share Posted June 24, 2007 Mine is 10mph fast. The HUD is correct though. To bad i cant see it unless i sit all the way up in the seat and crane my neck, its WAY out of alignment. I think my tach is off to, either that of the idle is high, most likely a mix of both.

stargazer7467 Posted November 11, 2007 Report Share Posted November 11, 2007 that sticker didnt happen to say D&B auto radio did it? Out of Carol stream , IL? I called them today , $282 to repair the panels. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted November 11, 2007 Author Report Share Posted November 11, 2007 Nope, it said AJR International, out of the twin cities in MN. Quote Link to comment Share on other sites More sharing options...
90TURBO Posted January 27, 2008 Report Share Posted January 27, 2008 I soldered a 1M ohm pot across the calibration resistor, dialed it in until the speedo was dead on. Sorry, I didn't take photos or measure the resistance when done. TGP is gone to a new home, so won't be able to do it now. Quote Link to comment Share on other sites More sharing options...
joberlee Posted January 27, 2008 Report Share Posted January 27, 2008 The place we use in the Detroit area is called Specmo. They do nice work and it tends to hold up. It's the same place all the local GM dealers send their stuff. I can get you the number on monday if you want. Quote Link to comment Share on other sites More sharing options...

Sorry, I didn't take photos or measure the resistance when done. TGP is gone to a new home, so won't be able to do it now. That's what I've thought about doing, pretty straightforward. Is there a similar calibration resistor for the tach? My tach reads fast too. I doubt there is, but just thought I'd ask. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted January 28, 2008 Report Share Posted January 28, 2008 My tach has to be off, because I was having trouble getting her to stay running today (low batter + I think I now have a vac leak), but she would drop RPMs and try to stall at 900-1100, which definitely sounded more like 400-500 (which would make more sense) Quote Link to comment Share on other sites More sharing options...
