Choosing the right CPS..

[Andy348]

I've got an M20B25 out of an 87 (no clue what month) and I need a new CPS. I've been told by Blunt that they change from 8/87 and upwards. What are the differences between the early and late ones? Were the early ones the flywheel sensors like the etas?

Or is there any way to identify my engine as either 8/87+ or -?

Thanks.

I see the same part number used for all M20B25 engines.
