They said this roughly translate one turn of the sensor relative to the brass hex.

I did not want to copy their email without their permission, but if you PM me I can forward it to you.


Lastly, I already made preparations for my un-adjusted SM sensor. I don't really want go back to the adjusted one which has a unknown number of turns. It could be right at the edge where the sensor does not work and I want to avoid having that potential risk.

So far the level of adjustment that teams are suggesting they need, they are way outside the +/-2PSI of adjustment Nason is recommending. While i think adjusting this sensor is legal, for me personally, +/-2 PSI is too much work for me to care for. The risk of disabling your sensor by going beyond 1 turn of rotation, I would not recommend the adjustment to any team. it would be far simpler to order a SJ sensor, and not worry about that risk.

thoughts?
