Are you wanting to know how to make the car idle rough to make it sound like it has a choppy camshaft?

[JDautoElectrical]

Tuning a car to run rough, is not the right way to go about tuning a car. When you hear of people doing a ghost cam tune in the newer engines with variable valve timing or other variable camshaft engines. The reason that can cause it to run with a lopey idle is cause of that it does have variable camshafts. So there is no way of adjusting valve or camshaft timing with the ECM tuning. If you are looking just for the sound. Go buy a camshaft. Don't make the car run crappy to make it sound cool. Tune the car to make it as smooth as possible.

try a clothes pin that holds a card in your spokes.

increase over/under speed spark adjust to over compensate adaptive idle correction and it will chop .......
