In trying to chase down some stubborn KR we have looked at various tunes and while contemplating false knock due to a Maggie blower on the motor, we could not help but see the differences in the L33 Aluminum Block 5.3 and an LM7 5.3.

So I am curious and want to know what an experienced eye can tell us about these differences.

Anything on K-Sensors and Maggie blowers would also be welcomed also.

Thanks

 

I wonder if the false knock doesn't resonate thru the iron block like it does thru the aluminum one.

 

Have you disabled burst knock? A blower setup will be far more prone to burst knock due to its instant boost ability.

And I wouldn't trust what I find in stock calibrations entirely...I've found a number of problems in many different tunes that I couldn't wrap my head around. They aren't always perfect

 

Not yet. Thanks

 

Which one of the tables look more sensitive?
