Gauges, stepper motors, and 85mph speedos
So here is my dilemma, I have the factory square dash in my 93 Blazer. tach is good for 5000rpm, speedometer is good for 85mph. needless to say, this isnt going to cut it for a stock LS1, let alone one with a turbo.
I already have a gauge face designed and figured out, now I need to change how the stepper motors work. How do I go about this? change or add resistors? Different stepper motor? I reallllly want to stick with a factory-looking cluster instead of going to autometers or something similar.

You should be able to program the PCM to send a differant pulse rate to the speedometer to correct it. There is no stepper motor in the tach, its a straight meter movement, if i remember those dashes correctly. Why don't you just convert it to the digital dash for that year, its a fairly easy swap and the speedometer will display past 150 MPH, if i remember correctly it starts blinking out at around 180.

I agree, I'm not as concerned about the MPH as I am the tach. I'm pretty sure I can take care of that by messing with HP tuners. as far as digital dashes, even if they had them for the Blazers (NOT S-10 blazer, we're talking real blazer, aka fullsize) I cant stand digital dashes. dakota digital makes one for the fullsize thats a plug and play, but again, i'm not into digitals, even tho they look awesome.
here is the cluster style we're looking at.

Yes, HP Tuners.
I may have avoided the whole problem, just bought what is supposed to be a 454SS cluster from a salvage yard in texas, if it is, there is my 6000rpm tach and 110mph speedo. I can handle that for driving daily, any track duty and I'll have the laptop opened up beside me.
