91 ZR-1 Can the Speedo cluster be updated... - ZR-1 Net Registry Forums

HI All:

Can the '91 ZR-1 cluster be exchanged with/updated with a later year cluster?

Unknown but I would love some of the features the 92 came with in my 91 with the "guages" function. Great question.. Has anybody done this? Or would the BCM/CCM come into play here? Anyone? GC

Short: No

Long:
the 90-91 LCD uses a different data pattern from the CCM then the 92-96. you could install a 92 ccm and cluster in your 91, I did on my dash conversion when I had a 91 dash in a 89. BUT I still did not have the extra digital gauges and I had a communication error between the CCM and ECM. you could possibly run a 92 MEMCAL in your 91, but I would verify that all the pins are the same and you have a correct ECM. IF all the ECM pins are correct and you had the CCM, ECM, Cluster and MEMCAL for a 1992, it is possible that it will work.

That would be a cool thing to try, but keep in mind the CCM stores the mileage for the car as well

Oh yeah, I think you will also need the DIC membrane from a 92-later DIC to work correctly

Would be a neat project.
