| How do you know when it's set up properly. I'm no tuner but is it really that simple; connect up,plug in laptop, select program, disconnect and away you go. Does disc come with unit? How do you know that your particular engine is running at it's best just ticking over in the garage. Does it need to go a dyno to be checked. AND what happens if everything goes tits up.
Sorry to play devils advocate, I really would prefer to fit one but when it comes to electronics I am very cautious. Mechanicals fine but electronis! It's all black magic to me!!
Cheers
PS where did you get it ?£170 is cheap, I though they were getting on for about £300 |
