What seems to be the normal learning curve for learning to tune? I am a mechanic by trade so I am not new to cars. I know the basics behind tuning and I know what I want the car to do. I am just having a hard time learning how to translate the info from the tables of numbers and graphs. For example I know my car at wot gets rich from 3500 rpms all the way to redline. I know it needs to be leaned out and but I don't know how to transfer that into efi live. I have been reading alot of data logging and it is helping some. Are there any good books to read to help learn more about tuning?
