After doing much testing with the Blazt USB interface and my software, it's working 100% without any problems at all. I used it on my 90 NA, 90 TT and 93 TT. It worked all the time, every time and made connection to the ECU every time without a problem. However, using the consult interface with my software takes additional initialization commands at different times especialy when changing to different polling commands to keep it communicating. I'm convinced the design of the consult interface is not so good and from what whatsthegoodword was saying it sounds like the design of the software that comes with the Blazt is not so good at handling things (it is good software though). The consult works fine with the consult software when it's working but I and others have noticed that it sometimes takes a little bit of messing with to get it to talk (probably related to the interface design) and it may also crap out after some period of time. One thing that could be helping my software while using the Blazt interface is that I'm using binary mode to communicate through the interface. xtensive gave me source code for the ztalk program and had mentioned that some people were having problems with the communication. What I did was convert the byte structure routines used for polling to binary format although actually I had to redo most everything from scratch because of how different the routines were compared to what I had been used to using. xtensive's software uses text format for communication. Communication in text mode can be sluggish and choke when used for serial polling at speeds of 9600 baud or greater. Not trying to knock xtensive, I found this out the hard way myself and learned from another programmer about how to use the binary mode. I gave xtensive the source code to a little program I made which uses binary mode for serial communication so he could experiment with the routines. The consult and it's software is fast in how it displays the information for the amount of things it can poll at the same time. This leads me to believe that the software is probably using binary communication (There is a way to snoop the data lines to see what type of communication is going on but I'm to lazy to mess with it right now and it's not really that important) but I still think the interface design is not so good from the results I've seen. It is an older technology in its design, just look at the size of the thing. Also, the consult software does not want to work with the Blazt interface.
