what is there to learn. when the guy install the turbo, shouldn't he tuned the air and fuel ratio to the right amount? so why should i worry about the air to fuel ratio. or running lean.
Its a good idea for the user to know how his engine modifications work. What if some guys comes up to you and asks you what kind of turbocharger you are running, and how it works? Are you just going to look confused and not have an answer? That would be the stupid thing to do. I like to know how things work before I put them into my car, so if a failure occurs I now what I can do to prevent it. I don't want to show up at the shop everyday with some minor problem that could be fixed easily....its a waste of time for you and the tuner. It is hard for them to just set the proper A/F mixture on our car since we have such an advanced ECU, which constantly monitors A/F ratio. That is where either the Gaurdian or K-Pro comes in. The Gaurdian(although its not out yet, requires no tuning) constantly monitors you A/F ratio to make sure the car does not go lean and will shut you down if it does happen. It also gives some functions that the ECU originally had back to it for it to control. The K-Pro is a stand alone system that needs to be put on a dyno where a preset map for a fuel curve is created to supply the engine with enough fuel. Hope this helps a little.
