I picked up a Hypertech Power Programmer3 model 30005 at a swap meet today cheap....
Seems to be a model specific ecu tuner for the American GM ruck 4.8/5.3/6.0 l.
I am wanting an ALDL interface with the 16 pin obd2 plug on board for the commodores etc. There seems to be some circuits out there to make your own has any body played with these before?
Getting back to the Hypertech - I have the choice of selling it on ebay and using the cash towards a scanner or interface cable or ratting the cable off it to make my own interface or stick with the paperclip and mil light.
Does an ALDL interface do much more for you on the commodores?
