Default What is this "hole" for?

Engine is B230fk in 1995 940 estate.

It was on the exhaust side at the back which connects to the gearbox.

B230FK - 95 940 https://imgur.com/a/gqkxwsw

Any help would be appreciated.

I keep thinking about using this sensor with MS as the cam signal so I can run wasted spark.

Not to nitpick, but you don't need a cam sensor for wasted spark - and you'd need something turning at half speed, like a cam.

Yeah you're right, it would hit that sensor 2x per combustion event. I'm trying to buy a DSM CAS setup right now. I'm getting intermittent signal drop outs from my 2.2 distributor, I'm just tired of screwing around with it. It was a weak link before with EZK, it just transferred it's issues to the microsquirt. I'm thinking it's the pickup itself because when it drops out I can downshift and everything comes back to life with the higher rpms.

IIRC, the sensor there in the 2.2 stuff was strictly for diagnostics, right?

Yes it was, I have a microsquirt though that could probably decode that sensors rpm signal. I'm using the 2.2 distributor for that signal now.
