Its good software, I've got some issues with Cobb but thats just because they arent making any custom JDM APs anymore now that they've released their V2 software; I had the money set aside for an AP but they wont make anymore custom JDM ones despite the fact that they've done so in the past, oh well ECUedit will do the trick for free. V2 has launch control and maybe anti-lag that isnt available for ver1 but if you dont want those you can pick up a used v1 for much cheaper and spend the money on a protune.
