Discussion and questions related to the course Understand AFR
so u cant tune with out a dyno rt. great course but I don't have dyno.let me know .thanks
Yes it's possible to tune without a dyno. Both of our practical tuning courses include road tuning modules that cover the process. Of course there are some downsides compared to using a dyno but if you have no alternative then you need to accept these and move on. I spent the start of my career tuning 4 WD rally cars when we only had access to a 2WD dyno so I spent a lot of time building up techniques to get the best results from these cars. Years later when I had the opportunity to re-tune a couple of these cars on a 4WD dyno I found my road tune to be within a few percent of what I achieved on the dyno.
