Hi guys here is my first post and I really hope I might be able to help a very important thing in gasoline engines, but also those of the diesel, I speak of the ADVANCES...I have recently mapped a scooter with an engine highly processed...and I've read two maps, one of the scooter is original and the other a scooter with the same engine and the same fuel injection and I noticed that the curves of the advances were totally different...now I would like to ask what has changed? why? the only change is the advances? the problem ? the curves are totally different...if you want to place the images of the two curves of the advances so maybe if you want we can talk about it thank you to everyone who I take? this question is mental
