They're both LH 2.2 ECUs, so they should be pin-compatible. The only thing that might be different will be the fuel mapping in the EPROM. Between '85 and '87 they made a few changes to the fuel mapping in the 900. My guess is that the 9k mapping reflects those refinements.
I couldn't say whether you'll see much of a difference.
It's well worth a try. FWIW, I'm running an ECU from a '90 900S in my '89 SPG without any detrimental effects. When I get time, I have one from an '89 9kT and another one from a '90 900T that I plan on swapping in when I have some free time.
