exileperformance Posted April 27, 2019 Report Share Posted April 27, 2019 I have a Thunder Set up on a BBC with LS coils, Holley 36-1 Crank trigger and MSD cam sensor. I believe I have everything wired right but not getting spark or anything on trigger scope. Am I missing something? If I do ignition test the coils work. I feel like i'm missing something on the setup. Firebird Tune (1).pclr Quote Link to comment Share on other sites More sharing options...
exileperformance Posted April 27, 2019 Author Report Share Posted April 27, 2019 Update!! I'm getting engine rpm off of the cam sensor. I also switched crank trigger to halls/optical to try but no luck.. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 27, 2019 Report Share Posted April 27, 2019 Trigger 1 will need to be set to optical/hall and I would say turn the pull-up on. Set trig 1 filtering to 1. Set trig 2 to reluctor and trig 2 arming threshold something like the example below. If you get no RPM with these changes can you do another trigger scope and attach it here.

exileperformance Posted April 27, 2019 Author Report Share Posted April 27, 2019 The MSD Cam Sync is a Hall Effect sensor I can only get RPM if I set it to hall effect. If I set it to reluctor I get no rpm. I have had spark today but lost it now. where to I want to set the cam sensor? At TDC or where my typical timing is at? Do I need to give the cam sensor any lead like 10 degree.

exileperformance Posted April 27, 2019 Author Report Share Posted April 27, 2019 Well it runs!! I'm not sure if everything is right or not but when I lock timing to 30 deg and check it with a light its right!!! I'm not 100% sure what I did today to make it run it seems like I tried everything last night. Anyways I attached the Trigger Scope and PCL file. I ended up setting crank to falling rate and had to set cam sync to Halls/Optical I couldn't get any RPM to show with cam set as a reluctor. Anyways still alot of work left but atleast its going. Thanks Adam for the help! Running.llg It Runs!!!!.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 28, 2019 Report Share Posted April 28, 2019 Correct, your cam is a hall. All pictures I could find of an "MSD Cam sync" showed a 2 wire sensor hence me suggesting to set it to reluctor. Quote Link to comment Share on other sites More sharing options...
exileperformance Posted April 28, 2019 Author Report Share Posted April 28, 2019 Does the trigger scope look like I have everything set right? Quote Link to comment Share on other sites More sharing options...

I would only change the RPM filtering on the trigger setup page, this should be on 1 for most engines. Quote Link to comment Share on other sites More sharing options...
exileperformance Posted April 29, 2019 Author Report Share Posted April 29, 2019 Thanks! I somehow ended up with my filtering for the cam sync set at 3, what am I looking for to see what I need for filtering? "Noise" in the trigger scope?
