msd DIGITAL 7 PLUS !
 

I bought one of these with data accuisition and replaced my digital 7 old model. Tried to fire it up and it will start , but will not accelerate. Just like its firing on one cylinder. Reloaded the stock map and it still wont go.
Switch back my old box and it fires right up.
anybody run into this before?
Called MSD and they said it might be inverted crank trigger wires. Hmm so why does my old box still work?
just wondering.
any MSd guru's there?
