MS: when turn the key to ON - car jumps
 

Hello,

one more problem with my MS1.

the car starts and works fine. idles, runs rich but runs.
but every time I turn the key to ON, my car jumps.
I think in that time my coils shoots and burns fuel left in cilinders.

what can couse this problem? could I set something wrong?

this is well documented. make the car unrich and it wont be as bad.

Or do either the Joe Perez or Reverant mod to the spark out, and then set them to Inverted in your tuning software to stop the spark plugs firing when the MS is turned on

correct sir.

or just laugh when you see your boost gauge flicker to 10psi on startup. Thats what I do :)

someday ill do joes spark fix
