i have a '05 EVO and i would like some kind of data logging device. The main thing i want to be able to log is A/F and engine speed. I can't find any type of datalogger for an EVO. I did find one made by scanmaster but i never heard of the company before. I do have a laptop that i can use if required. I don't really want to run a full EMS yet, so in the mean time i would like to be able to street tune my car with my SAFC-2. Any suggestions???? thank you!!!
