I've read the term "dyno tuning" several times. I'm still just a noob. I get the idea that you bring your car to a shop with a dyno. They strap in down and make a baseline pull. So the dyno charts hp and torque and keeps track of oxygen quantity in the exhaust gas to determine combustion efficiency? Is that right so far?
If the technician/tuner guy decides there are problems what do they adjust? Isn't everything pretty much controlled by the DME/chip? I'm sure the dyno would quickly reveal some big problems like incorrectly sized injectors but can stuff like injector pulse duration or timing advance rate be adjusted on-the-spot? Is that even altered at all?
This strikes me as the sort of task which requires a specialist to achieve best results. That is, a guy who just tunes BMWs or Subarus or Mustangs. I'm sure there are generic recommendations that could be made though. I'm still a long way from getting mine running, I'm just trying to build my knowledge base.
Thanks for your continued patience. As always, comments are appreciated.
