Sorry, not sure on that one. I'll see if I can find out.

If the LS2 sensor is on each side of the block, it appears that you have to drill the holes out to 8.5 mm and then tap them with an M10 x 1.5 tap for the LS1 style knock sensor to work.

Thank you for the info. That is not going to be fun now that the engine is in the car!

There may be other options. I am uncertain the difference between the two sensors... other than size. Could be something you can adjust for in the tune.

I read where you can thread the LS1 knock sensors in to one of the motor mount bosses, since I have the 1" setback adapter plates. What I'd like to know is if the sensor will work as it should since the material around that area is rather beefy.

I did see that as well -- you can adjust their sensitivity within the tuning software.

Pssh, turn em off and just tune off of AFR...nothing can go wrong there ;-)

Until the fuel pressure drops and you burn a piston...

Indeed, I was joking

**pajeff02** · 01-26-2015, 12:55 PM

I assumed as much, but when you have others reading these threads I have to make sure that they don't interpret what we know as a joke to be the gospel truth.
