lets say that on some1's mustang, there timing was off, now if the timing is too LOW, what would the car be doing? or if the timing was too HIGH, what would the car be doing, or is it the same thing, or in a nutshell, what does the car do when the timing is off, and is it bad?

 

On electronic ignitions timing is usually not a single value. Map is usually used.




This is because timing could be advanced as throttle is closed or rpm increases, and retarded as throttle opens or rpm decreases. For example, at closed throttle and 500 RPM timing could be 10 BTDC, but at 6000 RPM and full throttle it could be as high as 45 BTDC.


When timing is too low, your engine does not have the punch. When timing is too high, you get detonation, loose power and blow things. It is important to note that with stock Ford ignition map calibrations (even those for performance applications), it is hard to blow things. Also, aftermarket chip do not actually calibrate the map, rather they raise the entire map by an amount of degrees.


A good ignition map VS a bad one could mean the ability to let your wheels spin at wheel in 2nd and 3rd. An advanced mapping could shave a second of the quarter mile. Timing is actually used as traction control variable in formula 1 cars.

well he has an old stang so none of thT Chart info pertains to his car.It is not an electronic ingnition its a distributer so to much will detonate and to little will have no power

 

Ya can dump your distributor and put together a ford waste spark system for under $50. Gives better fuel economy and power.
