FX3 question - ZR-1 Net Registry Forums

EvanZR1 · 10-22-2018

I discovered the other day (getting car ready for going to the Mile), that while the car is a 1991 and Pete said the shocks were 91s when putting DRM coilovers on, that the FX3 controller is a 92+ unit. What kind of issues will this cause (if any). I have not been getting any errors, but the car seems too floaty even on the stiffest setting.

Should I try to find a 90/91 controller and swap it out?

If I recall the 92 FX3 controller spins the actuators a shorter distance. I would confirm the shocks, not that I doubt Pete, but the 90/91 controller does spin the shocks further when adjusting

That's what I thought as well. I need to double check the shock numbers, if they are 91 shocks, I'll probably try and find a 91 controller of Ebay to plug in. Alternative is putting the 92+ shocks that came with the coilovers back on.
