MommyTaz022200 Posted July 25, 2004 Report Posted July 25, 2004 My boyfriend's car has HUD and when the speedo says 65 the HUD says 71. I'm not sure if my HUD is different then my speedo since I can't drive it right now. Does anyone else have this happen too? It's only different at highway speeds. If this is common which is actually the right readout? (I would guess HUD but want to know if anyone really knows.) Quote
no1kicker Posted July 25, 2004 Report Posted July 25, 2004 HUD is always right. Our clusters are known for their inaccuracy. Quote
Guest Anonymous Posted July 25, 2004 Report Posted July 25, 2004 My HUD is off by about 2 mph... always go by what the HUD says, the dials can be off... what kind of car does your bf have, which has HUD??? Quote
midnight rider Posted July 26, 2004 Report Posted July 26, 2004 follow the hud. like everyone else says, the gauges are known to crap out. Quote
god910 Posted July 26, 2004 Report Posted July 26, 2004 It's not the gauges, it's the chip solder problems like GM is known for. My car used to have that problem, but the p/o re-soldered the dash, and no more problem. I need to re-solder my cutty dash, it is digital and displays about 5% of the time. :x Quote
supreme_style21 Posted July 26, 2004 Report Posted July 26, 2004 The gauge in my '94 is always off a few MPH according to teh hud. Quote
GnatGoSplat Posted July 26, 2004 Report Posted July 26, 2004 To make my speedo accurate, I had to piggyback a 1 or 10megaohm resistor across the factory calibration resistor. Yep, HUD is always the most accurate. It gets speed by mathematically calculating the input from the VSS. The analog speedo is just a voltmeter calibrated by a resistor. Quote
