Update: while up late wondering why I ever decided to get into cars, I thought about how I could simulate the motor turning over without actually turning it over, so I came up with the elaborate contraption below I then did a triggerscope while it was turning, and got a near perfect waveform, 0 trigger errors and steady engine rpm. I think this narrows it down to bad mechanical fitment, which I’ll dig into tomorrow.

This is driving me insane. Have a friend down the road with the same sensor on his rb25/30. He kindly loaned his sensor for me to try, and have done just that with the same issues. Still getting mass trigger errors. Did another triggerscope, I'll attach it. Trigger Scope Log 2022-06-27 10;35;31 pm codys sens.llg

During the early stages of putting the motor together, the sensor was actually rubbing on the wheel as I was turning it over by hand. I’ll attach a photo of what the damage looks like. Havent checked air gap properly but I would estimate about 0.5mm. No continuity from ring around bolt hole to either sensor wire.

Hi Adam, yes to all the above. Even went out and tried again just to double check, triggerscope shows nothing when trigger is out of bracket.

Sorry, misread that. Attached new scope with trigger plugged in, but out of bracket. Also attached a screen recording of link software while turning over with trigger back in bracket, if that's any help. turn over.mp4 Trigger Scope Log 2022-06-27 4;34;04 pm trig out.llg

Correct, shielding cut off at grey plug. Pin 7 & 8 measure out at 853.7 ohms. Trigger scope attached with trigger kit unplugged. Thanks adam. Trigger Scope Log 2022-06-27 3;41;12 pm trig unplugged.llg

Hi Adam, Have used the loom provided with the ecu. Using the black and white cores from the black cable for trigger 1, into the black and white on the cam trigger side. I’ll attach a photo of that. Unsure if polarity is correct, I’ve tried both ways but feel the issue isn’t related to polarity on its own. And yes, the cable provided with the yelsha trigger isn’t shielded - I’ve temporarily moved it well away from any other cables just while testing. Cheers

Thanks for the reply - have attached trigger scope with 0.5 as arming threshold at 0rpm. Trigger Scope Log 2022-06-27 2;23;42 pm 0.5.llg

Hi there, complete noob here. Finished wiring my link into my rb26 and having trouble with my Yelsha D 24-1 cam trigger. Wired into trig 1 using provided shielded black & white. Set up in software with (i think) the appropriate settings. Upon turning the motor over I'm getting some super weird readings. RPM is all over the place, ranging from 140 to 3000. Trigger errors everywhere, about 2-3 per second. Trigger scope looks super crap, unsure if its actually reading teeth or noise. Tried changing arming threshold values, rpm filtering, still similar results. Been battling with this for the last couple days and it's now beyond me. If it matters, I've been using another vehicle with jumper leads between to help crank it over. I've attached a few trigger scopes with different arming thresholds, along with the base map. Any help appreciated, keep in mind I'm very new to this.
