Does anyone know if this sensor is used in determining fuel injection timing? Reason I ask is that I am considering drilling and tapping the intercooler right near it to plumb in water/meth injection, but I want to make sure it wouldn’t have an unsafe impact on timing. Ideally, there would be a knock sensor to keep timing in check. Anyone know if there is one of those?

Thanks for any help!

What are you trying to gain by adding water meth?


i think EGT sensors are the biggest thing that limits power, so if W/M reduces EGTs you should be good to go.
