I had to walk away from this for a little while.... Was a little frustrated. Went and got a coffee. So when i got back I just reassigned the crank sensor to an02, hit device->program. Then assigned it back to an03. Then device -> program. Cranked and boom fired right away. Now she's running. I guess...

Definitely. Double checked its in the correct pin location, and i have a trace confirmed on an03 now. Something weird is going on here i think. With a solid trace on cam and crank there's no reason it shouldn't change the syncState to turn. Plus the fact that I can't see any new data in the synclog ...

So i opened the syncscope and i am still not seeing anything being read no matter what mode i click in the bottom. Cranking, live, etc. Nothing happening. Its showing the exact same data that it has since this all started. I dont have any clues in the bottom right. No errors present. https://drive.g...

I re-pinned the crank signal wire over to pin D23 and switched the io config to AN03 per Ryan's suggestions. I now have a trigger signal coming into the ecu. However the syncState and runmode still only read STOP. It doesnt even recognize the engine turning even though theres a signal on crank and c...

First thing i did this morning was try shorting an02 signal at the connector to block ground to verify i wasnt having a harness ground issue. No change to input voltage. Then Ryan suggested trying to unpin and repin to another input. Before doing that i wanted to test i have signal with an oscillosc...

I shorted sensor ground and input again just after I confirmed continuity while monitoring an02 on SMon. No voltage change. Just confirmed now that it is indeed set to 5v bipolar. I suppose I could try pinning it to another input. But like you said, why did this fail? I only have like 10hrs on the e...

Here is what we have so far. I am leaning towards input on the ecu now. I have confirmed continuity from the harness plug that the crank position sensor plugs into back to the harness plug at the ecu. I received the new crank position sensor i ordered. I plugged that brand new sensor into the harnes...

Alright so this sensor has 3 wires. While monitoring a trace on an02 I took a small piece of wire and jumped out all three combinations. None of them resulted in a change to the reading. Still holds at a constant 4.961v... That being said this is all factory wiring. The chances of the harness random...

No matter what i do i cant get the syncscope to show live data. No matter if i click cranking or live. Nothing new is appearing in the log. I don't have any errors either. The syncstate remains in STOP and doesn't switch to TURN. Still seeing no feedback from AN02. I have checked the wiring and conn...

I tried looking at the synclog while cranking and nothing happens. I suspect since maybe the ecu isn't seeing the crank sensor it doesn't switch to "TURN" and therefore won't initiate a log. When viewing the sensors directly I see the cam sensor (AN05), but not the crank (AN02). I will att...
