Exactly, but I was waiting to hear his logic on this car, lol.By retarding the spark. Used to be able to do this on Harleys hence getting the Potatoe-potatoe-potatoe sound at very low RPM. When you accelerate, that's when you first get misfiring. Unfortunately, it can't be done on electronic modules...only on mechanical distributors.
Just take the sound from a recording and run it through the BOSE sounds system with windows and power roof all opened.Speaking of potatoes and all...I would like to replicate the huge overlap on the big cams in those old big block muscle car engines. Would be hilarious to pull up to a light and hit the "Sport" button and get a nice big overlap cam and hear "lump.....lump....lump" out of the little 500.
