Lance,

I set the decel fuel to 100% and tried to play with AE with no good luck at all. Still seems like not enough fuel (backfiring hard against the pop off valve) or too much fuel (activating acc LED with attempted tip in or just idling at around 900 to 1300 RPM). Then I re-routed the battery and ...

Lance,

Since I installed the MS_II card I can set the tpsdot & mapdot threshold to 255 and any combo of 0% to 100% in the AE Wizzard and still get the (green) accel LED on the MS controller to light. any # lower than 255 and any % will cause the green LED to blink while idling ...

These problems have been tormenting me since I built this car in '08. I thought the MS-II, which I installed during this past winter, would help because of the 12X12 tables, but no dice ...

Thanks again Ken. It's up and running. I see you have a Corvette too. Mine is a '57 with a GMC supercharger and Hilborn hat.

Thanx Ken. I intended to do that,but I guess I was looking for a reason for the problem.

I'm thinking I will lose my registration password when I reinstall.

I allowed TS to update yesterday and when it said TS will restart, it didn't. I tried to start TS with the icon, same result. Shut down the computer and restarted it this morning and TS still won't run. Is there a problem with the update? Thanks.

Thanks Kholman. I hope I do this right. http://www.youtube.com/watch?v=OLWw4sO5Omo It works! That was interesting. I learned something new! This, I hope, will get some one interested in what I'm up to with this car. Thanks again for the education!

How do I upload a video? I'm going to try again. Nope, it won't do it. Says "connecting" for a while then I get a new "post a reply" page. It's a ".mov file.

This what I did. I set the magneto up on my distributor machine and tested it for DC volts and AC volts. Ran the mag slow to simulate cranking and got .002 to ~1.15 erratic volts DC. as I sped the mag up, the voltage hung in at around .07 volts DC. The AC numbers were - slow ~3.5 volts AC and as I ...

My mag is one piece (no external coil), so that module won't work according to autometer and a couple of forums I checked. I do know that terminal can bite if you touch it. I'll set the mag up on the bench and run it with a drill motor and see if I can get a volt reading and, I hope an o-scope ...

Matt,
Did I miss understand your question about a tach adapter?
Dennis

I don't think there is because I always got the tach signal from the same wire when I was using carbs but I did not use a tach and the MegaSquirt at the same time. I have not seen an optional device for a Vertex other than a relay that grounds it with the ignition switch. I was looking at using an ...

I am in need of a circuit that will boost the output of the kill wire on a Vertex magneto. when the mag gets hot (engine block temp) it quits triggering the opto-isolater. It worked while the engine was in the open air but when the body was installed and I was able to drive the car three years ago ...

I like it! Thanx.

Yes. It seems to need a little more fuel than it has. Ether priming pulse or hot cranking pulse modulation. priming pulse is like pushing the gas peddle down on a carb before cranking engine. I'm not in favor of that method in your case so I'd first play with the hot cranking pulse widths. I let ...

If you hold the peddle down some will it fire faster (too rich)? Look for black smoke, otherwise maybe a richer priming pulse.
