[AK1161]

Hi to everyone.
I have recently purchased AK1161 , a 1986 mkiv with a 302efi engine.
I would like to know if i need any software or a program to be able to tune it and any info that may help me get started on this project. At present it is a little lumpy on idle and lacking in power.I am not trying to achieve anything extreme but have very little knowledge on the subject and need to be pointed in the right direction.
Thanks to all.
Luke
