Yep, I got the two mixed up.

I had to adjust the potentiometer on the board for the signal strength of my sensor. Sounds like you might too.

Thanks for all the ideas. I think the switching between ignition outputs will work. I will have to run the ms board and the Toyota ignition off the one reluctor wheel. anyone had problems doing that?
so I had an idea to avoid a switch that I could forget to throw and possibly blow the head gasket ...

oh I get the switching Idea...I could do that. Is there any other way though? I already don't like all the spaghetti I've got strung through the cab and engine compartment of the car and really I don't want a "start up sequence" to the car that if I forget, could cause a head gasket failure. I guess ...

What are you using for an ignition module. If HEI 7 or 8 I put a switch on the control wire so I start on my initial timing and then switch over to MS timing. For rotor phasing I like to have the rotor in the cetner of the #1 post when the engine is midway on the advance curve. You have a way to ...

I thought about that so I cut a a distributor cap to see.

so at zero on the crank,
the rotor is pointing at cylinder one and reluctor wheel is pointing at the sensor pickup. as a side note, if I set the motor at 12deg advance the rotor would be closer to center. I had it set that way so I wouldn't ...

I'm still having issues with my car. I really don't know what else to check. Anyone have any thoughts, theory or suggestions??? My last post I was just trying to say I'm not waste anyone time without checking the basics first. If you have ANY feedback, I'm listening.

I had someone suggest that If ...

I've checked timing many ways. I had it set more than once. I used the trigger offset first and it worked. After the problem got worse, I made the sensor adjustable and since the sensor was already on a bearing so it could rotate around the reluctor wheel for stock advance, all I had to do was find ...
