A what? Sounds like nonsense to me. All you need is the computer and the loom and to wire it into your existing loom via instructions off apexi. You can put it in without a tune just don't touch the settings part except to change it to a 6 cylinder (don't touch the air/fuel ratios). The rest is done when u take it in for a tune.
