Ok so I got to do some testing with different maps and this is what I found. Where I ride here in east TX the trails are single track more flowing then tight and your pretty much always in a turn, very little straight-aways. I’ve done the GYRT ECU and throttle screw and opened up the air box, and FMF Core pipe. I first tried it with the GYRT ECU set at all 0, uncorked with the FMF core pipe. If I were riding open trails or a west Texas style hare scramble this map would work great but not slower technical stuff. This set up pulls hard everywhere and is hard to control in slower technical stuff. Next I tried the GYRT FMF map and it seemed to have smoother power delivery to me but it’s still too much for my type of riding. I then tried a map I found on here that RSWR450F posted. It was map 9 of Phil Andrew set up for longer power and less hit down low. This map for me worked great! It took the snap away down low where it was jerking my arms out and making it hard to negotiate technical trail. Now it’s smooth down low but still has the punch mid to top for when the trail opens up. I didn’t change to another map this day because I was having too much fun with this one!. I going to try some of the other maps on at some time when I get the chance to ride again and I’ll post the results.
