Default JB4 tune in B48 530e - 09-14-2017, 11:41 AM

I am a longtime n54 platform JB4 user, interested in the G30 B48 530e. The 530e seems to have a unique BMW ECU tune of the B48 outputting 181 hp and 240 lb-ft torque (this is much lower than most implementations of this engine, I believe lowered by BMW so as to not outpace the 530i when hybrid motor is engaged). I have a few questions regarding the JB4 and the B48 as used in the 530e:
  1. Does the tune interact with the electronic dash used in the 530e?
  2. Any experience/thoughts on interaction with hybrid electric motor assist?
  3. What kind of power can be expected from a stock engine setup with JB4? (Keep in mind the 530e starts with less output than the 248 hp and 258 lb-ft torque found in the current 230i, 330i, and 530i)
  4. Can the tune be used with autotune and e85 mix with an ethanol sensor? What is the expected output?
Thanks in advance!
