No, I don't know of anyone with a Delta Dash.
Ok, on to the Cobb stuff....there are 3 products that make up the whole AccessECU thing. First there is the AccessECU which is a reflash done by Cobb, cost is about $350.
The second part is the AccessPort. The AccessPort will allow you to store maps and reflash your ECU using one of your already stored maps. But you cannot manipulate them.
Finally, they final part is the AccessTuner. This will allow you to manipulate and change existing maps as well as make your own.
The AccessECU is already available from Cobb and has been so for about a week or so. They plan on releasing the AccessPort in about 6-8 weeks. And, they have been working on the software for the AccessTuner and MAY be able to release it at the same time as the AccessPort

.
I was told that Cobb will be requiring you to have the AccessPort in order to get the AccessTuner. They don't have firm pricing, but they are aiming to compete with the Utec and other do-it-yourself tuners....so they estimate 900-1000 dollars.
Personally, because of my timetable because of work, etc. I think I am going to try and wait Cobb out and do this.
