stim for 8 tooth VR with Cam sense??

Post by fuelyman »

I need to stim this format, can either/both the megastim or jimstim do this? I see some mention of cam sense signal but just want to confirm which one to buy.

Thanks!

A JimStim with the current release chip can do this.

This page lists them

I don't think it is presently linked from anywhere so you won't likely have seen it.

Thanks for the link, does the 8/1 mean 8 crank pulses and one cam pulse? The flywheel looks to have 8 evenly spaced teeth that pass in front of the VR sensor.

Ah, I think the pattern simulates 8 "crank" teeth for every 1 cam tooth, so not quite what you need. However, with the right cable, you can upload your own wheel definitions to the Stim.

Yes thats what I'm after, 8 crank teeth for each single cam signal pulse, but if custom configs can be loaded anyway I'm sure it will work for me. Thanks!
