No set timeframe. There are some changes we want to make that I haven't had a chance to full test yet.

Is the 32_2 I beta tested the same as the full release? Just wondering if I need to update my firmware or not.

Hey Terry any chance of getting the channel down button to over-ride the boost limiter?

We can move it if there is a consensus. Volume up too annoying?

It was set on volume for manual trans drivers.

Si very annoying ! I believe last time you indicated you could keep volume up and add the channel button(s) as well...I need this as road conditions vary greatly up here.

Has anyone else noticed that cyl 2-6 timing seems to always be a matching value? In my logs cyl 1 has variance, but 2-6 show the exact same value as each other 99% of the time, including corrections. Every so often they will vary slightly. Doesn't seem quite right to me. Definitely running the right option, have been using it for a long time. 32.2 and BMS 2/23 BB BEF.

The movement seems normal to me? The refresh rate for cyl1 is 10 times per second while cyl 2-6 are around 4 times per second. So maybe that is what you are seeing?

1) Posts to this thread that contain bug reports, logs, or tuning questions will be deleted without being read. If you need assistance post to the support forum.
2) G5 board must have diodes removed as shown in the photo below to run this firmware. BMS started shipping all boards as ISO early 2014.] We've removed the diode photo to avoid confusion but if your firmware date is 10/1/12 before updating you need to cut them off before uploading ISO firmware. Click this link for the photo.
3) For a more in depth discussion on methanol settings and how to use map 3 without methanol read here.
4) Some addl info on custom tuning the JB4 boost control..
5) If using a 3.5bar TMAP sensor set "N20 TMAP" to 1 and if using a 4bar TMAP sensor set "N20 TMAP" to 2.


How do i know if i have an ISO board since some people claim it is supposed to be written ISO on the chip box... Mine aint.. ???

Thanks for looking.

If you look at that section of log, during the 3rd gear pull, you can see it most pronounced. Then post shift, in 4th gear, it seems more normal but 3-5 are still seemed linked. The short pull in 4th earlier in the log has them all the same too. I just wouldn't expect 5 of 6 cylinders to have the exact same timing down to the .1 throughout the duration of wot, especially given my crappy pump gas results.

Maybe you are right though and it is just an artifact of the sample rates and I am reading too much into it.

I tried to capture it in this mspaint:

I think that is just a sampling artifact because when you look at the chart you see a sample point or two later they all match up again.

Your board clearly says N55 Stage 2 so why are you in the JB4 for N54 thread? Believe here's the one you want and the first post should answer your question.

hey terry maybe you can point me to a post that explains the updates in 32_2 better

i plan on experimenting with the MHD only bef

In regards to leaving the white connector in or out. when using 4/4 setting.

white connector out logging and guage hijacking only i get that.

with it connected I have to leave jb4 in map 0 or i will get no boost. is that what im understanding?

Quote:
G5_ISO_32_2

1) Adjusted 3.5bar and 4bar TMAP FF scaling to auto compensate for new range. If you change the sensor you no longer need to retune duty bias or change FF. If upgrading from an older firmware FF should be lowered ~15-20% to speed up adaption.
2) Made menu11 gas pedal mapping range wider allowing for more aggressive behavior at higher settings.
3) Reduced boost taper on BEF map1, map2, & map5.
4) Moved CANflap to an on/off toggle on option 4/5.
5) Menu4 options are now as follows: 4/2 BEF, 4/3 no BEF, 4/4 Flash Only. Default is 4/3. Note the new menu 4/4 option and details below only apply to those who are not using JB4 tuning and simply want to use the JB4 for gauges and datalogging. If you are using JB4 tuning and/or JB4 back end flash maps read no further.

When mode 4/4 Flash Only is selected the follow occurs:

A) On any map other than 0 the JB4 acts like map4, bypass mode, with JB4 logging/gauges active. The JB4 does not change or alter the tuning. If using JB4 controlled meth then meth will flow on maps 3, 6, and 7 but without a safety system and ignoring whatever boost target the JB4 is programmed to for that map.
B) If you leave the white subconnector installed, the JB4 runs boost targeting using its user adjustment settings including menu 10, 12, FF, duty bias by RPM, anti-rattle, etc. The target is always equal to the flash boost target but the JB4 runs the actual wastegate control. This is useful for switching back and forth between flash only and JB4 maps without opening the DME. Also lets the JB4 mask one of the common problems with flash tuning which is the boost control.
C) If you put the white only subconnector back to stock, as shown in the photo, and what I've done for the flash map testing, then the JB4 and its boost control settings have no influence at all on boost control. It's 100% strictly logging and gauges only.
D) With option 4/4 selected map0 disables the JB4 CANbus module all together allowing for OBDII logging via the MHD. The catch is to use map0 in this mode then you must also run the configuration outlined in 3) with the white subconnector back to stock. The JB4 can not properly control boost without its CANbus module active so map0 on option 4/4 will result in zero boost unless the white subconnector is placed back to stock.
