It would seem to be a really smart way to tune a chipped ecu car on the cheap yourself. At least worth the $39. Tunnerstudio software is half the reason I'm looking at Speeduino/Megasquirt options in the first place. Are you trying it with the free version?load nearly any csv or delimited file formats. If you find a delimited log file it doesn't load just contact us at EFI Analytics, ods are we can have a version that will load it in no time.
