Emu black- dbw/rpm increase

I have recently got a first start done on my Cosworth YB engine.
I am using a Bosch 68mm throttle body and calibration wizard has been run successfully.

When the engine is started, it won’t have a steady idle, the rpm increases on its own.

If I unplug the throttle body and start the car, the idle remains steady.

Is this likely to be a setting issue within the software that needs to be changed?

Ur idle settings must be wrong. U probably have a too high idle valve DC in the base table.
