After repairing my old sensor twice (and replacing the oil pan after the last whack cracked it), I bit the bullet and bought a replacement sensor.

Suggestion

But a good number of M9X owners decided to just replace the IMSB with the Retro or Solution and just not have to worry about it for a time (Retro) or permanently (Solution).

Suggestion

Probably would be a desirable tool today for those with original IMSBs that don't want to replace theirs until they have too.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

After repairing my old sensor twice (and replacing the oil pan after the last whack cracked it), I bit the bullet and bought a replacement sensor. Looks good, except that it sticks out about 3/8 to 1/2 inch lower than the old one. I'm thinking about adding slanted runners to the skid plate equal in height to the distance that the plug sticks out below the skid plate. Has anyone done this, or is there an aftermarket fix for this? And yes, I know, try not driving over things that go bang under the car..

POST 2 / ORIGINAL POSTEROriginal post

Installed, it sticks out about 1/2". Plus, it looks like a sturdier metal, so the impact will transfer better to the sump plate. Not to disparage LN Engineering (or Jake), but I wish it was shorter. Still, I wouldn't run without it. Just have to watch closer for the road turtles and tire gators.

POST 3Original post

Make sure you take those speed bumps slow and at an angle.

That's probably what got me this last time.

Mind my asking how you repaired the unit the first couple of times? I�ve had mine on my car for a very long time and the wires have only now broken for the first time. I�d buy a replacement if I could find one but nobody has one anymore.

I'm on my third sensor all three started to leak due to either two seperate idies forgetting the proper torque number or just bad luck ...tried to source a new one but Flat 6 sold their stock to an undisclosed company who wishes to remain that way The unit still works but forced to employ the Harley shovelhead protocol from 50 years ago....cardboard

POST 7Original post

IMS Guardian? Holy cow it's really a thing. https://www.pelicanparts.com/techart...S_Guardian.htm

POST 8Original post

Yeah, it was pretty cool at the time. Like a real time UOA. Probably would be a desirable tool today for those with original IMSBs that don't want to replace theirs until they have too. But a good number of M9X owners decided to just replace the IMSB with the Retro or Solution and just not have to worry about it for a time (Retro) or permanently (Solution). Pretty cool to see the evolution of solutions over the years, with probably alot more on the way. With over 500k M9X engines around the globe, inventors have a rather large market to sell too.
