Chipset Posted April 19, 2011 Report Share Posted April 19, 2011 Hi i want to ask the experts about the basic steps - tricks for the proper tune . My car is a Silvia s14 (sr20det) and i have all rdy made it to nice point where most of the map is good but because the whole tune made by me alone on the road , driving - logging ---> fix the tune and repeat i manage to make my tune perfect only on those places-spots on map that im usually while driving out. What i mean is that my afrs are rock solid under constant coast and wot which is easy but are so unstable ( lean rich ) in places that i cant hold long the engine on the road ( almost full vacuum etc ) So i decide to go to a dyno and make let say my map (s) in 500 rpm steps until i reach 0.5 bar boost and then complete my 0.5 ++ map by logic (so that i don't have to stress my car too much on the dyno) . What i want to ask is what most of you do when you are on a dyno and more precise how do you handle the correction maps like IAT correction. As we all know on the dyno the temperatures are much more higher than on the road. Do i have to temporary disable IAT corrections and tune on the dyno in small steps ( let the car cool down and restart ) or do i have to tune using those correction maps ? Thank you very much for every answer that i may get Quote Link to comment Share on other sites More sharing options...
