I know its still labeled as "beta" but has anyone used the JB4 tune on their FK8 Civic Type R? https://jb4store.com/collections/honda/products/burger-tuning-bms-honda-1-5l-turbo-jb4-beta Link to it above.. I used a JB+ on my 228i and it worked pretty well. I was hoping to hear some success stories on it. I prefer these to a full ECU flash for warranty reasons. Thanks!
