I have found this on ls1tech.com. I know it is not new, but if the info is good and correct how could I apply this to efi live. Since it seem to be written for HP Tuners. I think this would be a good sticky if someone could just make it so it could apply to efi live. I am really wanting to learn how to tune correctly. My goals are to be able to tune my car with the MAF. Thanks for any help in advance. Heres the link. http://www.transamws6.net/HPTuners/ls1tuninginfo.doc
