MSD rev limits without pill?

My MSD 6AL seems to cut my motor out at 4000 rpm. disconnect MSD and motor spins cleanly to 6000. I can hold my foot flat on the go pedal, screw the timing back and forward, nothing will make it go over 4000. does it regardless of what pill is fitted.

Could someone please throw some light on this, i am at a complete loss. I want to keep the MSD if possible. have it hooked up to a standard ford clevo dissy as per MSD instructions. Id like to be sure I have installed and set it up correctly before I blame the electrics in the MSD.

Any suggestions?

Re: MSD rev limits without pill?

What else is wired to the coil?? How is the box wired to the coil.

MSD specifically states -:

* The only wiring that can be wired to the coil is the orange and the black wire.
* The factory insulation needs to stay on the wiring. Otherwise you can get interference.

Both cause an early rev limit.

After that try another coil and recheck wiring. Make sure you've bypass the factory ignition module.

It's all simple/silly stuff really.

Maybe I'm wrong, but if you disconnected the MSD it shouldn't run, should it? Sounds to me like the factory modulee is still wired in.
