Anthony Parle Posted January 9, 2022 Report Share Posted January 9, 2022 Hi, We are trying to get a LS2 started and we are getting Yes on both the Cam and Crank Trigger but I think there is something wrong with the Crank sensor or the settings. The trace doesn't look clean. Have the settings on Crank sensor Optical/Hall, Level 2, On Pullup, falling edge. Any suggestions greatly apricated.

Adamw Posted January 9, 2022 Report Share Posted January 9, 2022 Yeah that doesnt look right. Does it have grey or black sensors? Quote Link to comment Share on other sites More sharing options...

Adamw Posted January 9, 2022 Report Share Posted January 9, 2022 Have you got a small mirror or endoscope or similar you can look down the hole to confirm its got the 58X wheel in there. The scope almost looks like it has the 24X wheel in there or something. LS2 should be 58X and you have the correct sensor. 24X has got two discs with different patterns stacked side by side. 58X has a more common 60-2 type single wheel. Also, confirm the sensor is wired like below, be aware the cam and crank pinout are different: Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted January 9, 2022 Author Report Share Posted January 9, 2022 It turns out the engine builder used the 24 tooth in the LS2, we changed to the correct sensor you showed above but we no longer got any signal from the crank. We checked the wiring and we still haven't done any good. I wonder if the 24 wheel will work in a LS 2 / L98 block. Do wee need to change any setting in the link for the 24 tooth??? Tomorrow is another day. Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 9, 2022 Report Share Posted January 9, 2022 The 24X sensor is meant to have 12V (or 8V works but I dont know if 5V will. 24X cam sensor pinout is different but the crank pinout is the same. Yes I have seen the 24X (Gen3) sensor and wheel work in the Gen 4 engines. They need the matching single tooth "half moon" cam. Trigger mode for the 24X system is "LS1 5-10" Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted January 10, 2022 Author Report Share Posted January 10, 2022 Hi Adam, as usual you got a use sorted which is why we used a Link ECU on the job. Its a friends hand built Lola T70 from hand shaped aluminum sheet for the chassis, its a true work of art. Hand built throttle bodies etc Thanks for your help.
