1. Yes MS works seriel to USB connection, That is how I do it.
2. Yes also works serial to USB with wideband, I do that also. I did lose the wire that came with the LC-1 though to connect to a PC.
I should point out that I have been unable to get a decent wideband reading on my gauge since the day I bought it

. Due to my lack of ability and the fact that I gave up. I just bought a gauge (an innovate one) and im going to wire it directly to that, I could never figure out how to get the LC-1 to give Megatune a decent signal, it is either my dumb [fizzle] settings or ground signal noise. Umm yer, install it 100% better then I did when you do it. I found I couldnt understand the instructions, same lug but different bolt but same bolt etc. Too confusing

. Ramble over.
