Duron?

Probably don't remember me, but I had a red S14 KA-T when I was super young. Got to meet you at your father's shop.

It's really a function you don't need. It's pretty much saying after X RPM's it'll cut off that cylinder.

So instead of turning off all the injectors at fuel cut, it will cut them off individually.

its very good for using as a full power limiter that gets used constantly such as drifting etc. by setting the cut off rpm's maybe 100rpm apart on each cylinder
