Hi Jonny

When running a 2 wire unit the 4 and 6 terminal settings are ignored. Just make sure you have ISC solenoid select on the Aux output and not stepper.

You want the engine to be able to hold a low idle with no idle control before setting up the idle.

Start with open loop first and get that as close as possible before switching to closed loop.

Do i still alter the settings in the idle setup apart from 4/6 pin or is it the frequency I need to play with in the aux menu.

The car holds idle without idle control on. I had to adjust the butterfly to allow more air in and play with the ign timing but now holds around 850-900. But would like the solenoid operating

Thanks

The figures will all be in duty cycle and will function as such.

Have a look at say the Nissan base maps these are set up to be a solenoid controlled idle.
