hi guys my names Justin im from Australia, i have been interested in tuning engines for quite a few years now. i have been paying hundreds of dollars on a membership here and watching the webinar videos trying to learn as much as i can. i have just recently lashed out and purchased the EFI Tuning fundamentals, Understanding AFR and practical stand alone tuning courses ( i should have done this along time ago). here is my first question, what is the best way to put my new learning materials to the test without access to a dyno? should i run logs on the ecu trying to stay in specific sites, then go back and adjust and do another log and compare?

Hello and welcome

a good idea is to log every thing study the way it looks and then try adjusting small areas of the fuel map to see what it effects on the logs and compare the two logs

this will give you a great understanding of how big of a change is needed to adjust the fuel correctly

Thanks for the tip Ross. Definitly keen to start tinkering with things
