MSD Digital 6 plus

[01Z]

Question:

I understand that the ignition on the LS1 and probably LT1 produces all the spark needed but the MSD box has the adjustable soft touch rev limiter.

I may be adding nitrous and would like to cut spark rather than fuel when the rev limit is reached. I understand that nitrous with the fuel cut at the rev limit simply toasts the motor in a moment of time.

Does anyone recommend the MSD digital 6 for use with a nitrous system with the LT1 and/or LS1?

If so, what harness would I need for my LT1 / LS1.

Or is there a safe, cheaper alternative to fixing the rev limit situation?

Any help is appreciated.

probably would get better responces if this was posted in the nitrous section

with an A4, you can just set the rev limiter higher than the shift rpm. a window switch should also accomplish what you want to do. have it disengage the nitrous like 500 to 1k below the rev limiter
