When you read alot of Tazzi's posts, he often says that he is inundated with emails... but im sure he will get back to you.
I have bought both OSE and the airbag software off him... and since one my car is a ls1, one piece of software uses the elm327 cable and the other uses the aldl cable.
If your desperate he has a store on ebay, so if you search
envyouscustoms on ebay you will find that there says there are cable/software packages available there...
keep in mind that the software keys are a one off, so if your like me and starting to have a failing laptop make sure you either have a system backup or be prepared to buy a software key again if putting it on a new laptop.
