i wanted to use this to upgrade the spark on my leading coils but the web site i am going to order it from says not to use it with a distributorless system, so i wanted to know if anyone is using one and to tell me which type they are using the odd firing one meant for V6 only or the one that is compatible with 4, 6 and 8 cylinder cars.

i had one on my na s5 fc, acutaly lost power and had a hard start. ditched it went back to stock and the problem went away. 2 weeks later bought a jacobs rotary pro pack . installed the jacobs box and actualy gained power, easyer starts and the features that the jacobs box had was far beond anything msd offerd. damn i cant spell for ****. long story short, i wouldnt use and msd box on the s4 or 5 but would recomend the jacobs rotary pro pack

MSD's Are peices of crap, for less money you can get the jacobs and have there 3 step rev limiter box for cheaper than what you can get a 6AL and a two step
