What ballast resistor do you use for the aftermarket electronic ignition system?
OK I will try. Not a engineer but a ex avionics guy.
Basically the lower the ohm value the hotter the ecu gets and you will get more RPM's out of a ecu. Great example are chrome ecu's. Alot of cars run them and they are a good unit on the street you should run say .8-1.0-ohm ballast and you will get lower rpms out of it, so the heat does not build up. When racing they recommend a .25 ohm to get the max output RPM's of around 10K but they are also turned off and cooled down between runs. If you use that on the street, I will give the ecu a hour on average before it fails. Most of the new Mopar "authorized" kits with the Chinese ecu come with a 1 ohm ballast. But they seem to overheat due to the fake transistor cove and the newer style one is buried in the potting on the back so no place for the heat to escape to hence more failures. That help?
Here is a simple way to think of amperage.
A 1/4" straw and water will let the water (amps) flow a good amount (think amps)
a 1/8 straw will restrict the amount of water (amps) to the unit so less amps.
You reverse this for how ohms work .25 ohms would be the 1/4" straw less restriction more voltage, the 1/8 straw would be say the 1 ohm ballast so more restriction less amps.
That help anyone?
