i was helping a friend today getting a street tune going on his gsr using s300. with the ecu connected, it wouldnt stay on the high cam timing/fuel maps. i would select the map to make the appropriate changes and it just immediately switched back to the low cam.

with the usb disconnected i could select high cam maps and it would keep the tables open so i could make changes. now i dont use hondata often, am i missing something in the smanager?

 

Turn off datalogging or un-select "tables follow VTEC" under options to make changes to the high speed tables while connected to the car.
