Getting there!
I needed to develop a quick and easy cam sensor solution to see if MS could run stable using the LH2.2 distributor and a single cam sensor. In other words, a 4/1 CAS.
This was my solution:
First I welded a tooth to the back of my cam gear for my sensor.
Then I welded a bracket to my valve cover and mounted the hall effect sensor. This particular sensor comes from a mid-90's 3.5l V6 Chrysler. I found many of these in the junk yard. It worked really well on the bench, we'll see how well it works on the car. And there it is, my cam sensor solution:
Time to see if it all works. I rigged up my sequential ECU to the car. I tapped into the signal coming off of my distributor and wired up the cam sensor. I set the ecu as a dual trigger toothed wheel, 4 and 1 both at cam speed. I started the car up and took a composite log:
Success!!!! The distributor and my cam sensor solution sync up just fine!
After that I set the ecu into COP mode and hooked up a coil to the #1 ignition output channel. I did this to get my trigger angles set with the timing light while the ecu is synced up to the engine. One less step to do when I actually install the ecu.
I took a guess based on where my cam trigger was located and was greeted with this surprise when I checked the timing with the timing light:
My guess was a degree off. I got the trigger angles set and now the ecu is ready to rock. I've ordered the stuff to make the wiring harness and will receive that some time next week. Next post will probably be the installation of the ecu!
