TFI Question

[dkmcgowan]

I know, there is plenty to read about this. I just have a couple of questions.

I did most of what is called the TFI setup on my CJ7 with my 258 except for the Ford e-coil, the larger cap/rotor, better wires, gap to .45.

I read for the first time about this resistor stuff and I went to check the CJ7.

1st question: I tested the positive side of the coil in the on position, battery 12V, coil 9V. So it has a resistor, which is good, I don't want to risk anything. When cranked though and warmed up, the battery is about 14.34V, and the coil positive side is 11.34V, is that still OK? I put my hand on the ignition module and it's warm, but not hot, you can hold your fingers on it as long as you want.

So my next question. I had always planned to do this upgrade for my new 79 Wagoneer, but after reading about peoples failures, I got worried. I have all the parts, I would leave the resistor, I don't want to go HEI or anything. I am building a daily driver with this one, should I just return this stuff and stay stock? Is that more reliable?

Thanks!

When doing the TFI swap, the plugs dont get opened up until the hotter coil is added. With the can coil-.35, Ford coil- .45.
I have never changed any of the wiring on mine and it has been just as, if not more reliable than stock.

Just my .02...
