VGT Vane Cycle

[k2davis1]

For you guys out there with the VXCF9 flash that cycles the vanes how often do they cycle? Does anyone know what triggers the command to cycle? I had Matt write me a tune to cycle vanes on my VXCF4 strategy and sure enough he pulled it off but I cant figure out whats triggering a cycle and there is definitely no pattern to it.

Very hands on with my truck just tryin to figure everything out. thanks

Length of idle time in park triggers it

mine will cycle sitting at a stop light

He mustve wrote it that way then.

Mine cycles at stop lights to. Mine seems like it does it all the time. I don't remember it ever not doing it.

Did the MKM write that into your tune? Which tunes from MKM are you running?

my factory VXAP2 strat on my 04 cycles the vanes like VXCF9. Stopped at a light, in park, or rolling slow in reverse with no throttle - vanes are cycling.

how can you tell when it cycles

You can hear it if you listen to your exhaust. You'll hear the turbo hiss/whistle get louder as the turbo cycles.

I have VXAP1 and mine cycles in park during idle. Never heard it when in gear.
