sorry, just jumped on to find the vac. tuning for my brother's msp today for the 440ccs but anyways for the problem of not being able to connect, make sure the cable is not really long, I had that problem, also if it doesn't work with the car on the "on" position, just try turning the car on, like, engine running to connect, if it connects, then turn it back to the "on" position with the car engine off, if that doesn't work then it is something to do with the type of cable you have or maybe you don't have the correct software with it or something that like, maybe a setting on your computer,,
I had explained a while back as to how to change your COM ports for the connection on your computer settings, or something like that, it was a while ago. but just play around with the connect, and making sure your computer is on before you plug in the serial port, stuff like that
edit: well crap, can't find the map I was looking for, I could have sworn that at some point there was a 440cc map in here that tuned in vacuum. I will look more later, better to just start doing tuning on my own for now.. hopefully I can get somewhere with it, I hate tuning the 440cc RX racing injectors on my brother's car
