Idle Air Control with Haltech Elite 550

Good morning people.
I have finally finished my 4g93 sohc turbo install.
I have the Haltech Elite 550 wired up and working well.
The only issue i'm having is with the idle being to high when stationary.
I am new to ecu programming but I'm loving what ive learned so far.
I believe i need to connect the IAC stepper motor to the ecu.
From what i have discovered it apparently requires 4 outputs/inputs? And with the Elite 550 only having minimal connections this is difficult.
Has anyone had experience in this area?
Thanks in advance.

You cant mate. the person who sold it to you should of advised you that the basic ecu doesnt do 4 or 6 wire stepper motor so for engines like Mitsu and Toyota it will pose some restrictions.
It can only do PWM idle.
To use 4 or 6 wire stepper you need have to use Platinum or Elite 1000 or higher.
They call it an Elite but the 550 is very basic.
