Does the eight point timing curve address rpm above 4000?

Would we need an exhaust gas analyzer for tuning the timing curve?

Thanks,

It will come with the plug-in programmer.

When you first plug it in, It will read the current assigned ign table, and store it in the programmer... then with each change you make to the ign map, it will always store the last ign map that was programed, so it stays in sync with the ign map in the cdi box.

It will come already setup with a basic ign map / curve that will run any 2 or 4 stroke engine.

Well above 4000 rpm , due to how the ign advance sys works based on an ever diminishing delay time from the base / static ign timing setup... you setup your base timing anywhere up to 42 degrees advanced, and then set or map each of the 8 ign points to any given rpm / degree point on the table.... if you duplicate a point with the exact same rpm and degree, you will only have 7 ign points, so you can reduce the number of ign points used on the ign table down 2 or 3 if you desire, but the duplicated points have to coincide with each other consecutively in order to reduce the number of mappable points.

No gas analyzer needed, but you will need to retune your needle settings of course, or your solenoid mixture curve .

It has an rpm output... and it will also have sbus2 for telemetry, that's what we are working on now... it also has a throttle servo plug port, so you can plug the throttle servo directly into the cdi box if you dirsire, but not required... I added that just to make it convenient, as most place thier throttle servo up in the nose of the AC.
