THIS PART IS LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND IS NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) This part may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THIS PART IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BURGER MOTORSPORTS, INC, AND CAN VOID YOUR VEHICLE'S WARRANTY.

We'll use this thread for our upcoming B9 Audi S4 SENT JB4 BETA updates, map guides, firmware, and discussion!


Install Guide here: http://www.n54tech.com/flash_files/audi_s4_install.pdf

Optional map changing, datalogging and updates are done using the BMS data cable or JB4 Mobile REV3 bluetooth kit.

Map guide as of v4 firmware:

Map0: Stock tuning, disable JB4
Map1: 2psi peak over stock (default)
Map2: 3psi peak over stock
Map3: 4psi peak over stock
Map4: 6psi peak over stock, E85 mixture, race gas, or octane booster suggested
Map5: 6.5psi peak over stock, E85 mixture, race gas, or octane booster suggested
Map6: Custom tuning map, can be used as additive by setting RPM1500 less than 5psi, or absolute by setting it greater than 5psi.
Map7: Water/Meth (WMI) Progressive Mapping
Map8: Low Boost/VALET map. Runs 30% less boost than stock.

JB4_AUDI_S4_4_T4:

1) Revised maps per above. Changed map4 to performance map, adjusted map5 target, changed map7 to WMI map, changed map8 to VALET/low boost map.
2) Logical revision to correct 233F false alarm fault code some got when letting off the gas.
3) Tuning change to improve boost performance on tip in.
4) Added support for BCM (boost control module)
5) Added support for map6 to be used as an absolute target map in conjunction with the BCM, we expect this will be useful for those running larger turbos. When using map6 the boost value entered under "RPM1500" determines the profile. A value of 5psi or less makes map6 an "additive" map meaning the value is added to the stock boost level. A value of map5 or more makes map6 an "absolute" meaning the JB4 targets that specific boost value. The logic does not yet allow for targeting of less than factory boost levels so if you enter an absolute target below the stock target you'll receive the stock target.

JB4_SENT_AUDI_S4_2:

1) Adjusted warm up temperature safety to avoid bug with it kicking in when car is heated up.
2) Added cyl6 knock correction logging. Adjusted cyl 2-6 logging parameters so they show much higher values, to make boost/octane evaluations easier.
3) Created a firmware split so "S4" firmware will be used for all six cylinder models, and "RS3" firmware for all five cylinder models.


AUDI_JB4_SENT_T7:

1) Adjustments for WMI integration.
2) Potential fix for bug that lights off every code in dash when letting off gas suddenly on higher boost maps.

AUDI_JB4_SENT_T6:

1) Added map5 which is 6psi peak over stock, for race gas and E85 mixture experimentation
2) Added knock monitoring in cyl5. Will add cyl6 shortly.
3) Added flash boost target logging
4) Changes to avoid triggering 9023 manifold pressure too low fault when letting off the gas on higher boost maps

How to update firmware:

For firmware updates if having issues we suggest you turn off WiFi, change upload timeout to 25, and set your phone next to JB4 box under the hood.
