I have a Racechip. That video spooked me off the JB4 of which I’ve had many over the years. But if you’re interested in the JB4 poke around on N54tech.com in the M section.

Condition based service gives you a reminder like any other service due. You should also get notification on mybmw

Did some short drives the first 3 days to get some good heat cycles in, then roughly 350 miles a day for another 3 days. |

The LS / LT engines I build go 20 min first start and hold from 2-3k rpm for 20min. Dump oil change and inspect filter. If all looks good it gets 100 road miles with lots of engine braking. Another oil change inspect/replace filter. Then it’s on the dyno for 1000+hP WOT pulls.
