Hi maxaircarbs,
I think the only reason I am replying to your post is I know how frustrating it can be. Firstly, I don't quite understand what Mach you are using. You mention OEM codes, but Mach 4, as far as I understand, doesn’t use OEM codes anymore. All things Mach4 are accomplished via Lua scripts.
I think OEM codes were used in Mach3.
So let us first get that bit clear. If you are using Mach 3 then this is the wrong place to post, if Mach 4, then we need to be having a different discussion.
If you use Mach4, then I at least may be able to help you to get your Cycle Start working.
