Im brand new to this whole deal so forgive me if I sound like an idiot.

Basically ive come into the world of EFI Live (4) and ALDL while trying to troubleshoot an issue with vehicle ive restored, the glorious Lada Niva.
This model uses a GM/Rochester 700 TBI and a GM ECU.
I built an ALDL interface and bought a full licence for EFI Live. Im using a definition created by a Lada fan decades ago, this is working well enough for basic stuff but there are no macro's or anything, cannot send commands etc. Also the timing stats are wild and I think, inaccurate. (60BTDC..)
My question is, how do I go about obtaining data to allow me to update this definition? Any guru's on this tool?
Cheers,
Ash
