torque gauge?

[dave8590]

any one know how to do a torque gauge or if its even possible on a '97 Z71 5.7L

i know the chevy SSR had one and i thought it would be somethin cool to have

anybody know?

the only question i have is "why"

I doubt you would be able to make it work on your truck. They probably just take the TQ numbers off of an engine dyno and replace the gauge face of a tach with the TQ numbers at a given RPM. Ex. 5000rpm= 250 ftlbs, 2000 rpms= 120 ft lbs. etc.

I dont see any other way it could be done, as the gauge likely doesnt measure actual torque output of the engine.

oh i see what your sayin,
i was thinkin you plug the gauge into the computer then that reads it

get on an ssr forum and try to see what they say

the computer saves a torque map in the computer for the transmission.. if you use a tech II you can see this reading while you are driving the car...it is RPM and MAP based so it isnt very accurate. but i suppose since any GM vehicle 96 or higher has this info it would theoretically be possible to display this on a gauge like the SSR does, but impractical for the trouble it would be

so i wonder if i get a reader that plugs in the spot the tech II does i would be able to get a display on the dash

this is pretty awesome, I never knew they came equipped with these.

I have a digital torque gauge on my RPD in my Cobalt. I don't think it's based solely on a torque map though. Since it varies a lot when I'm driving and how much I hit the gas I'd say it's pretty accurate. Honestly though, I have no idea how it works but It does look cool though.

if it were torque map based, which it is, it would behave exactly as you described.

I can just about guarantee the map is based on RPM and engine load (which is based on vacuum, MAF, and I believe TPS inputs). Mod the motor at all, and those calculations are going to be inaccurate for the most part.
