Clifton Posted June 11, 2009 Share Posted June 11, 2009 Ed, did you get your VR dizzy working? I'm having a similar problem with no RPM on MT. At least not during cranking. If I spin it by hand or with a drill I get a signal. Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted June 18, 2009 Share Posted June 18, 2009 I did get the setup to work however it seems the pickup is rather sensitive in the dizzy and mine went out. To get another one was 100+ so I scraped the setup all together. My Z has been sitting since then. Hoping to resurrect her this summer. EDIT... re-read the thread and seems a couple other have working setups, I just didn't seem to have good repeatable results. Quote Link to comment Share on other sites More sharing options...
Randall Posted December 14, 2012 Share Posted December 14, 2012 just curious what the final results were on this. Im going to be running MS2 v3.0. I plan on using the stock VR from a 280z instead of forking out the cash for a turbo distributor. Hoping i wont have any problems with this.

motomanmike Posted December 14, 2012 Share Posted December 14, 2012 I've yet to see someone use a pertronix on an old points dristributor to trigger megasquirt on an L series. I've read about people doing it on other cars. I'm really thinking about trying it on this carbbed car I have to run just ignition. Any of you in Z land tried it?

Randall Posted March 30, 2013 Share Posted March 30, 2013 (edited) Just thought i would add something interesting to this discussion... Here is the output for the 280z VR sensor from the FSM: Here is an excerpt from msextra manual: As you can see in the msextra picture our vr sensors are wired like the bottom figure (red) and we also have the output like the bottom figure which means we should be using falling edge unless we swap the wires. I saw a few posts saying to use the rising edge which seems wrong according to the pictures. I have mine wired as such but seem to get what is called timing jitter. The FSM states that a bad pickup coil could produce the opposite signal (dashed line in first image) which could explain this jitter but i do not have a scope to back this up.
