2021 Rocket 3 GT
This is a map I peiced together for my 2021 Rocket 3 GT, VIN AD2528 with DNA air filter and Carpenter racing TXL exhaust. The tune Carpenter sent me made the bike not work, which was exciting.

Looking at the penner tunes I discovered the ignition tables where wrong. The bike started with the 31013 map, so I took that map and put Carpenters air fuel ratios into it. I used penners throttle percentages for road and rain, Carpenters tune deleted these. I used Carpenters throttle percentages for sport.

The result is a bike correctly tuned for the exhuast system, per Carpenter, with rain and road set to the penner tune. Sport is very, very fun and I strongly recommend you set traction control to road until you get the hang of it. Put 500ish miles on this tune with no issues thus far.
