A little experience with the older systems. System not as user friendly, but not any worse than a Gen 6 DFI. Used to be fine when they had a distributorship here in Dallas, Texas. However as I have found out recently any work that needs to be done has to be sent to Australia. I am about to send a box back a second time since they did not repair it right the first time. Maybe their fault, maybe my fault, but either way shipment cost to and from Australia ($40 to and $80 back with export duties) takes them out of my list of candidiates on future installs. That and the lack of support here in the states. I think the box you are refering to does not work on a Buick DIS system, only HEI style. Also the lack of a wideband is a negative. Cost is compareable with the other units out there. Basically unless you live down under I would look elsewhere.
