XHP MHD JSR Help

[E90ST_WideBody]

I am getting ready to button up my single. I was informed I should get a stage 4 XHP trans-tune. My question is ( First BMW ) Can I change the trans tune on the fly? Or have it on with just the sport option? Any help in setting this up would be appreciated.

I don't believe you can change it on the fly. You would have to reflash, which takes about 5 min.

You could contact Rod Sutphin and have him build a custom tcu flash for you. Make sure JSR us OK with this.

Thank you. Excuse my ignorance. But who is Rod?
