I have been playing with the UTEC today. I powered it with a 9V battery (it has a useful power socket in the back, so it doesn't have to be in the car to play with the interface, maps, parameters etc). One thing struck me right away: my laptop hasn't got the serial port needed to connect it to the UTEC! thankfully my PC does, but it's something that will have to be sorted, my laptop has got a couple of USB ports, and a printer port, as well as phone socket and network socket, wonder if some other type of cable with different end can be bought for it.
Interface seems straightforward enough, it has the 2.3 software loaded on it (old one, they are now at 2.8d) as well as the map from Japtrix for Jaysen's car and some tweaked parameters.
I have practiced with saving the map and parameter files on the PC, with no issues. I have also uploaded another couple of maps (NA of course) that I had collected from the US sites, of users with similar mods to mine.
The setup of the hyperterminal connection was ok, no problems there either.
Now it needs to be put on the car, and need to find a tuner willing to learn the utec and tweak the existing maps to suit my car!
