joey.youssef Posted Wednesday at 05:26 PM Share Posted Wednesday at 05:26 PM Hello, I have installed the Jeep 4.0 I6 Cam Sensor. However, I am not getting a CAM signal on the composite logger. I did verify I was getting 5V, ground and signal to the switch. Jeep 4.0 I6 cam sensor I believe is an open collector hall. So I did jump JP7 on the MS3X board. R32 I turned it anti-clockwise many turns to ensure its all the way. R11 I used the ZC Testpoint, I got 2.41 V by turning it clockwise until it wouldn't go up any higher. I have the tunerstudio set to Toothed wheel, Coil on Plug, MS3X Cam In, Dual wheel with missing tooth. But still no cam signal on the composite logger. I'm going to move forward with starting the engine and breaking it in on the dyno using wasted spark. But I would like to get this sorted out... for others that are running sequential using the Jeep sensor and MS3X... can you please let me know what I may be missing.

DuffyMahoney Posted Wednesday at 09:35 PM Share Posted Wednesday at 09:35 PM Have you tried clocking it any? There is an area of the stroke that it won't work in. 1 Quote Link to comment Share on other sites More sharing options...
joey.youssef Posted Thursday at 12:05 PM Author Share Posted Thursday at 12:05 PM I followed the manual on how to set the position of the cam sensor. The attached picture is the manual next to what my cam sensor location is at. Only difference is my crank sensor is on tooth #6 from the missing tooth when engine is TDC.

joey.youssef Posted Thursday at 03:28 PM Author Share Posted Thursday at 03:28 PM I think I had a setting wrong in Tunerstudio. I had Second Trigger Active On set to Rising but reading the manual again, it should be set to Poll Level. I will make this change and try it again. I just need to get my flywheel back to try cranking it, might be a couple days. Do you think that will solve my problem of no cam signal?
