trouble installing white faced guages

[Dave Holman]

I just installed the white face guage kit from MAC. Although I was careful, I don't think I got the speedo needle exactly where it was before. Is there a way to get it exact? I know I could do some calculations based on rpm, tire size, and gear ratio but I really have no way of being sure the tach is exact either. All of the other guages read the same as they did before.
I know this may sound stupid to a lot of you but I would appreciate any input.

doesnt your x-cal do data logging?

 

[Dave Holman]

Thats a good thought. I'll have to call SCT or try their website for information on how to do it. My xcal came with a small users guide that only briefly mentions data logging. Thanks for the input.

get into the digital readout for your speed. drive down the road at 55mph or so, set cruise control and stick the needle on.

heres how to get to digital readout of speed:

Good idea. I did not think of that. I forgot all about that digital speedo thing. I used to set it to RPMs for awhile. Ahhh the good ol days.

same thing i was gonna recomend

I did the same with my MAC gauges, 03GTinFLA...it took a couple trips around the block, but now, it's 'dead on balls accurate'.

curious, why can't you set it when the car is off? it would be all the way to the left wouldn't it?

Will the digital speedometer reading be accurate even though I have 3.73 gears? When I used my xcal I used the appropriate setting for that ratio.

Yes it will...no problem.

You can blow on the needles and they'll move...literally. So trying to set the needles for 0 MPH and 0 RPMs isn't as easy as it sounds. And on mine, to be accurate, the tach never quite registers 0 now...it's a hair or two above the peg...go figure, but it's accurate.
And on the other gauges you'll wanna set them where they normally sit when running (and at operating temp) to be accurate (as possible). I snapped a couple pics so I could get them exactly where they where before the swap.
