If you mean “why would I pay for a dynotune when I have an LM-2” I would mostly agree. I couldn’t justify the outlay for either when my 990 runs very well with a borrowed tune. Where I don’t agree is in that I don’t have the time to do all the testing and modifications and testing that you must have ( and I’m jealous - that would be fun) The Dynotune and long extension cord were meant to be jokes, but the inverter wasn’t. If your laptop battery is bad buy a new one or power it off the bike and take it with. Also the TuneEcu Lite version that runs on an Android device has some Tune functionality- I just can’t remember how much, and have never used it.
