NEW JB4 Firmware - 23rd May 2012

Just a note to fellow JB4 users, new firmware is out dated 23rd May 2012 (US 052312)

Sounds like big changes to map 5 (and Map3 for meth users)

1) Revised map 5 auto learning for more aggressive and responsive tuning, including support for various E85 and race fuel mixtures. Auto tuning range is from 12psi to 17psi.

2) Revised map 3 progressive mapping for more aggressive torque response and smoother transitions between no meth flow and full meth flow.

Also, anyone here using the "AUTO DTC ON" function on the JB4?

I been using it for weeks, love it, the car is always ready for a hoon without having to press the damn DTC button.

But the cruise control doesn't work when you put DTC off manually. odd.
