It's working fine. I can't say I can tell any enormous differences. I would like to flash the old tune and the new tune on a switchable so that I can test the differences on the fly.
I had a similar problem and it ended up being a bad connection between the ip harness and the pmd cable extension. It was in the actual connector. The way I finally found it was while it was running i wiggled the wire from end to end, and finally found the weak link. Easy fix, or course.
The prices are great. The reality is that we don't yet have some tried and tested tunes. That is what is going to really make the deal. Otherwise, it's just cool to be able to burn your own chips.
I think this brings out what the issue really is. There is really a debate between a sharing community (what these forums are all about) and making money. Of course guys who are in it just for fun are going to be attacked because they knocked out a money-making opportunity. IMHO it's about time...
