MSD 7,000-7,100 RPM module needed

Too cheap to buy a whole set of these just for one.
Thanks,

You can just go down to radioshack and get a resistor.

the formula is RPM in Ohms - 1000 so a 7000rpm would be 6000 (6K) ohms. If you take an old module and crack it open you can see the resistor inside.

Thanks for the tip Eric. How do you get the resistor to stay in the socket?

solder is your friend

bring it by the house if you have issues with it, I can hook it up for you real quick.

Oh, and be sure you get at least a 1% resistor, .1% if you can find it, common is 10% and especially at higher values can make a big difference.

I'll try that. Thanks,
