Hey guys,
We've had these Built-Motor N54 knock sensors on our shop cars for a couple years now but mostly held them close to our vest. Enough interest has popped up that we'd like to offer them to the built motor guys searching for a method of reliable knock detection without using the current work arounds such as trim pots or desensitizing knock sensors.
A little background, once we started playing with built motors, particularly closed deck, we ran into the same false knock issues that everyone else with a built motor has had to work through. We hired a knock specialist to come in and size up what was going on, understand why the stock sensors weren't working properly anymore, and most importantly to learn what the appropriate steps would be to get us where we needed to be.
We start with factory BMW knock sensors then modify them to suit their new role protecting a built N54 without having to hassle with false knock. $799 per set, plug and play with the N54. Eliminates 95% of false knock on built motors with no changes to the factory DME.
These are the same custom config sensors @Terry@BMS is currently successfully running on his VTT/Rebello motor powered 135. I think it's safe to say Terry is pleased with how well they work but I'll let him comment if he's so inclined.
We'll add these to the website in the next day or so, none currently built up, we'll update this post (or thread) with a photo of them once we do.
Cheers,
Chris
