Troubleshooting FX3 Suspension
How in the world does one tell if an FX3 shock is working correctly?
I can tell a mild differnce between tour and performance, but nothing in between on sport.
I suspect that my system is not working at 100%, or it just does not deliver the amount of performace change i was thinking it would.
Any comments would be appriciated! Thanks!! :cheers:

Mine's the same way, not a big difference between settings. You can get your shocks re-valved and get a chip from DRM. You'll feel a massive change between settings then.

Re: Troubleshooting FX3 Suspension (Mervz)
those settings are speed dependant.
some autocrossers have it reprogrammed so the difference can be felt at lower speed.

Re: Troubleshooting FX3 Suspension (SloRvette)
I concur. As long as the dreaded "Service Ride Control" light isn't on, you're probably good-to-go.
Plus, it's cool to psyche the stool out of newbie passengers as you reach down to twist the FX-3 Selector Switch just as you're setting up for a hairpin turn! :lol:

Mervz, I still think your system is working perfectly fine from when I test drove it for you. I was switching between settings a lot during the drive and the car was noticeably (to me at least) different. There was much less body roll coming into corners harder in the stiffer settings.

Re: Troubleshooting FX3 Suspension (Mervz)
The service ride control light just came on in my 95 Z07. Local dealer inspects and sez rear shocks are bad + all 4 actuators are bad. I can believe that the shocks need to be rebuilt, but think it's about impossible that all 4 actuators died at once. :bs I plan to pull the top off the actuators and check them by watching for sproket rotation while turning the key to "ON", then changing the settings on the console switch. I will also clean and inspect all connections. I think I could check resistance at the actuator connector to make sure one of the connections isn't weak or bad, but I don't know what the proper resistance value is. My feeling is that the dealer is covering their a** by getting me to replace all the parts at the corners before they explore whether the control module is bad. Their incentive would be that GMPP won't pay for the shocks/actuators (!!!), but the module would be covered by extended warranty.

After some experimentation on the way home today, i'll have to agree. Its just not as much differnce as i thought it was going to be. Also, changing back and forth doesn't really give any sence of it. Its best to drive on Perf for a few miles, get used to it, then turn it down to tour. Its alot smoother... :)
