skipping engine cycles

Hi,
Just curious to find out if there is a possibility of tweaking the code, in such a way to enable "SKIP FIRING", ie to skip a fixed number of engine cycles. For example, skip 14 cycles and enable fuel injection and spark ignition at every 15th cycle alone.
I understand that the Rev Limiter tab in the MS Tuner Studio can be used as a method to cut "14 sparks out of every 15 sparks". How about the fuel injection?
Thank you very much in advance, for any suggestions.

Just curious....... What the heck are you trying to accomplish here?

Ken,
I believe that's what I have described in a short paragraph.
Do you have some solution to offer, to achieve skip firing using megasquirt?

You'd have to write your own modifications to the firmware to do this.

My apologies for offending you! Since I am not the sharpest tool in the shed, I was merely trying to clarify in my own mind what you were going to use, what you describe as "skip firing", for! I freely admit that my question was prompted by my own selfish need for self edification. I shan't bother you again!
Again, my apologies!

Thanks Matt. Yes, I'm trying to insert a loop which counts the number of cam trigger pulses and then sends it to the injector, when the condition satisfies to be true.

No worries, Ken! Thanks.
