Terry,

I connected my Stage 1 unit to my PC and when connected, I changed the boost safety to 4.0 but when I save the settings and it refreshes, it changes to 3.4. Does the same if I change it from 4 to another number. Seems to refresh to a lower number each time.

Is this a normal characteristic of the software/piggy back?

Thanks

[Terry @ BMS]

Perhaps you are using the wrong interface for your board. Screen shot of user adjustment page?

[13F10M5]

Here are before & after screen shots. Before is when I connect to the board and after when I save the setting which changes from 4 to 3.4. When I refresh the connection (disconnect/reconnect), it displays 3.4. I tried this on two different stage 1 boards and got the same results.

Pretty sure you got the wrong interface. This is for jb4. Not stage 1.

Thanks Gary for your response. I thought this was the case but Stage 1 interface doesn't connect and per the install guide, I am to use JB4 interface. See note below straight from their install guide.

If your box says "n63" in marker on it (and has //3 after the firmware date) then use the Stage1
interface. If your box says "n62-2" in marker on it (and has //4 after the firmware date) then use the
JB4 interface.

//4 indicates a G3_V2 board. So interface looks correct. What happens if you enter say 5.0?

Terry, same thing happens with 5.0. It reduces I believe by .6. I am not in front of my computer but I found that this happens with any value I put in that field.

Ill give it a shot again tonight with 5 and see what value is returned.

[13F10M5]

Terry,

I set it to 5.0 and once saved, it reduced to 4.3. I tried doing 5.1 and it reduced to 4.4.

It happens if I go up/down in values

Tried this on two different Stage 1 boards.

[13F10M5]

Terry,

Any suggestions?

Thanks

[speed808ix]

Had this happen to me, I just set it higher all the time.

[13F10M5]

I picked up a windows tablet for my car and noticed that when I change the values, it stays now. The issue must have been with my other computer. Glad it's corrected.

Thanks everyone for help

My box just says 63-2 on it and can not get any firmware installed with the BMS cable and i did mine the exact way the instructions say and now can not upload a firmware to the box. any ideas?

[Track Master]

Can you post link for the firmware update?

[Terry @ BMS]

There are no Stage1 firmware updates.

Hi Terry,
I just purchased the USB cable for my stage 1 (not JB4) for my N55. What are my options as far as what I can do with my stage 1? Is there an updated firmware now? The car has started to hesitate under medium throttle, so I figured it may be the stage 1, and wanted to see if there was a diagnosis I could run. Thanks.

[Terry @ BMS]

This is an S63TU thread, not an N55 thread.

But there are no diagnostics on Stage1 other than to check boost levels. Would need a JB4 for diagnostics.

[Gatchek]

My apologies. But thanks for answering anyway. Much appreciated.

how can i download the Stage 1 Tune for S63tu?

[Terry @ BMS]

There are no Stage1 firmware updates, so nothing in any of these threads applies to Stage1.

Is there a manual or user guide for the Stage 1 unit. I was unaware of the interface. F80 M3

[Terry @ BMS]

This thread is pretty old.

The Stage1 systems can have boost set between 0-4psi, it's already set to 4psi on //M models. You could technically set it to 5psi but generally a JB4 and its fuel control, CANbus, and advanced features are required for those levels.

Hey Terry,

Does the BMS Stage 1 tune for N63 work with the S63? Your website shows it as two different products, but this listing shows the BMS stage 1 will work on either. Any firmware updates needed?
