Yeah most of the tuning is done on it. I havn't really seen his thread (got a link?). Will probably go out one more time and it will pretty much be done. A tuning course would be great just to learn all the little tricks that you can't really pick up on by yourself. Like for example getting a car with a Power FC to idle properly seems near impossible. There is simply bugger all settings for idle and it may be perfect one day but then crap the next.
Also I find the hardest thing about tuning a car is not the actual tuning itself, but the damn troubleshooting of a problem. I completely understand why workshops love tuning brand new Holden and Fords. All the parts are brand new and there is simply nothing wrong with the car. With 15-20 year old cars, gone through 4 different owners with parts ripped off here and there just leads to so many problems that take ages to narrowdown.
I will get a kmon eventually because I want to hard wire it into my car so it pulls timing upon detonation. Would be good to use on Power FCs aswell because I don't really trust those factory knock sensors.
Havn't used Nistune yet. But I hadn't used a Power FC until two weeks ago and picked that up fairly quickly so don't see why Nistune would be any harder.
