I recently bought a twin channel plex knock sensor system too for my dyno but havent tried it out yet

I would like to se the results from these. My past experiences have me jaded towards them not being reliable enough to save a piston/pistons if timing, fuel pressure go astray.

Smitty, Here is the link to the male end of the TPS sensor harness. This is what I used to connect my Ford TPS to the Holley harness. This also is for the pressure senors.

mounted to the blower boss, square stock one side cut on an angle, flat stock mounted to it for the coils to mount directly to the flat stock

If you expand this photo it should show the mount

Funny story about Knock sensor and mefi. Before I had my own dyno and started tuning mefi, a friend of Mine, lets just call him "TYLER" tuned one of my blower motors on his dyno and then on the water. I think we had some mechanical knock or something on dyno so knock sensor got turned off temporarily. So fast forward, when I bought mefi burn and learned how to use it, I find the ONLY safety that Mefi really has , the knock sensor, has been turned off since motor has been in boat (like two years). I think of the times I held it at 6300 at 13/14 psi for 10 minutes a few times and Im just like OOPS! no ashtrays though, luckily!
