DRM custom FX3 controller. Anyone remember these? - ZR-1 Net Registry Forums

scorp508 · 3 Days Ago

I have a DRM custom FX3 controller on the way from JG95ZR1 with the AA208-1 chip to go along with my car's DRM coil-over setup. I'll likely leave the factory controller in other than for Autocross/Drag days.

These things seem a bit lost to the bowels of internet history, and I could not find much detail on them other than one mode is "full stiff" and the other two modes will let you dial in more/less over/understeer. DRM appears to have offered various chips, but the differences between them I can't quite discern other than some references to possibly road course, drag strip, and autocross options.

Does anyone have older DRM parts catalogs that may offer some hints? I'd love to track down the other chips if they're still out there, or burn them if I someone has the raw ROMs.

I reached out to drm@dougrippie.com to see if they have any archival information or dusty old chips to sell.

A few threads with bits and pieces of info.
