Setup instructions are a little confusing. After I figured that out, using the software was great. I can save different setups and upload them when I want them.
Received the USB interface and realized it had been used. Some of the documents were missing as well. This sort of thing happens on occasion and J&P replaced it with no hassle. Once I had the new/un-opened interface, the install went ok. The instructions are a bit cryptic, but after you get it hooked up correctly, it does make sense. I sent Daytona an e-mail and they replied quickly with helpful hints.
software is well done.. takes some getting used to.
I did not use the USB Interface, so I cannot rate it, although, am sure it's a good accessory to have. The J&P Tech said I needed the USB interface to fine tune my Harley, since I had a cam installed. But, I installed the Twin Tec Ignition, according to the instructions, it worked fine & my bike ran great without using the USB interface. So, I returned it, BUT I was charged fees I felt I should not have paid since the J&P Technician said I needed it.
I haven't started programming with this yet, but the instructions are very clear.
