Small update: Went back to the Dyno last week with a new tune. I am now using MHD+ Multi Map, as having just one full send map isn't that useful, especially this time of the year. Map 1: 16psi made 427whp and 577nm (This map is all I need on the street). Map 2: 21psi made 476whp and 663nm Map 3: 26psi Made 565whp and 863nm. You can however see quite a nasty dip up top especially on the high power map. (that map was actually 560whp and 808nm). This is likely a vanos tuning issue, my tuner has sent another revision, but also a result of timing corrections. I flash my old tune, which is the grey line on the dyno sheet, however the power still dropped off and has a dangerous amount of torque down low (Bendy Rod zone). The car pulled a bit of timing up top which robbed power, the ramp rate on the dyno was 2x more than doing a 4th gear street pull and the load was set to heavy on the Dynapack. The timing corrections are a lot better on the street.

From experience of a UK import: you will need to set your profile address to an address in Japan, then it will allow you to add the vehicle to the mybmw app. it will also depend if the modem in your Japan vehicle has a roaming capable sim. - ie it will still connect to the internet via NZs cell network.. it is not possible to change the “country of origin” of the car. let me know if it works- I’m interested to see if a jap sim will roam..

In a Z3, there’s only one other person to say “Watch this!” to.
