Had Mallory Hyfire that was causing problems I traced the problem to an output transistor that was arcing to the heat-sink under insulator????. This would burn up the very small transformer secondary windings shorting them and cause intermittent ignition. I purchased this product to finally rid of the to me designed obscene. This new unit had a much better transformer and kept the switch transistors off the heat-sink chassis so no High voltage arc to ground. Used in my stock HEI coil and GM 7 pin ignition module.
Still have my ECM control spark advance this unit emulates the output of module with a resistor load so not as hard on old HEI module. Also kept the capacitors away from heat sources. So far works great I would recommend this product to replace MSD or Mallory with no rev limiter. I do not know how this unit program rev limit. I used the white wire off igntion module so not sure about the low level pickup that would be someone else input.
I am happy with this product Thanks for cheaper alternative Multi spark ignition.
It was shipped quickly. I want on line and downloaded a pdf for the installation instructions.The warranty was a big selling point and the price was a lot better than other ignition boxes.Installed it and it is working great.It is a lifetime warranty compared to a 1 year warranty for all the competition.I would highly recommend this ignition box.
