Actually, data logging can be a great tool when fine tuning the IPR map. I was doing some testing/tuning last night for my extreme towing program (which really doesn't make much more power over stock) to get some things
just right. Remember how I said about a week ago that I had something to test? Well, I was working on that.
If you see certain trends in your IPR DC% that cause you to wonder.....
I'll post some datalogs and screenshots one of these days in the near future. I didn't set out to do any IPR changes, but I ended up making a few.
........and if your BO is that bad, then I think you need more help than just some fine tuning.
