FX-3 Control Module programming - ZR-1 Net Registry Forums

boostedmaxPSI · 04-25-2013

I have a '91 ZR-1, I do not have any codes and my system seems to be working as it should.

My car has a DRM FX3 Controller and a Bilstein programmed AK2116 (chip and controller) for 92-95 FX3 cars. My shocks have been re-valved by Bilstein to match the controllers program. Bilstein provided a customer program B-260 to work with the re-valving of the shocks and my coil over suspension for a complete package.

Here's the situation, seems my fronts are too soft in suspension travel. They do not seem to have the same firmness that the rears do when I move the selector switch to "Sport" mode. I get this feeling when I travel at normal highway speeds and I hit a dip in the road.

I recently picked up another FX3 controller (89-91 part) and 4 actuators for comparison between modules and chips, for testing only. After reviewing my Bilstein paperwork and looking at the FX3 module, seems I have an FX3 controller for a '92-'95 MY.

The cutoff year for the controller was October 91. Cars before this date would require the MY89 to MY91 controller. My car was manufactured late 1990!?!?! Why the '92-'95 controller?

Questions:

What is the difference between the controllers from MY89-91 and MY92-95. Is it just programming or a physical difference such as wiring?

What does Slalom 1 AX2116 actually do? Seems this is the entry level for road racing. Close to stock but a bit more aggressive??? just a guess.

What does the Bilstein chip with program B-260 actually do?

Again, system works and does not throw any codes. Just curious how the DRM FX3 module and B-260 with re-valving are different from the stock system.
