Fitting SC57 cluster on SP1

I'm trying to fit a SC57 cluster to my SP1.

Everything seems to be working, except RPM.
I've looked around a noticed people have fitted all kind of Fireblade (including SC57) and RC51 clusters on their Firestorms without issues, so surely this should work too? I mean, if both a SC57 and SP1 cluster works on a Firestorm, the SC57 should work on the SP1?

Any recommendations what/how to check?
The needle goes to max and back to zero when bike is powered on, so guess that means the tacho itself is working?

I can measure a slight voltage (0.01-0.02) across pin 18-19 (tacho and negative) when the bike is running? But it just a multimeter, it is probably struggling with so many pulses.

I've wired as below, looking into the back of the clusters.
