Uploading an older Firmware question ( B3601 issues with new update )

I just did the public release update last night. I was running this version.

EFILive V7 software: V7.5.10.323 (updated Feb 19, 2017)
EFILive V8 software: V8.2.5.316 (updated Feb 19, 2017)
Boot Block: V2.07.007 (Feb 07, 2014)
Firmware: V2.07.113 (Feb 19, 2016) (updated Feb 19, 2017)

Now with the lastest update i can no longer set B3601 below 10.00 AFR on my 512k LS1B ecu like i could in my last version. I am running E90 and need my B3601 at 9.50. Commanded AFR reads 9.99 now. I have redownloaded my last version but now i can not change the firmware back to the older version?? Why not? And why the change in the B3601 be limited to 10.00 AFR now. Can we get this changes back please?

Post your tune.

Current tune

Update. I put the new update back on my main laptop. Used an old laptop and put my old version on it and made the change i needed. Put it on a USB drive over to my main laptop and programmed it into the car. All back to normal now. Any way we can get this hard limit on the B3601 changed back to how it was in my previous version?

The LS1 calibrations have not been altered for a long time, I am looking at an LS1 tune now with the .calz dated 07 April, 2009 and the minimum limit is 10.0:1.
Do you have any idea how old your software was that the limit was not there? It is something I would have assumed always had a limit in there and if it wasn't it has been that way for at least 9 years.

I was using the software in the link below before i updated. It still shows the limit to be 10.00 - 20.00 but when i would put in 9.50 for my E90 fuel it would allow it and show 9.50 but put a red box around it. Im not sure if you have changed how the out of limits are read at some point. But with the new update it will not let me change it below 10.00 now, when i try it goes right back to 10.00
Here is the link to the software i was running.

Yes in the properties window there is a checkbox "allow calibration values to exceed recommended limits", make sure that is ticked.

I have that checkbox ticked... it still seems to restrict B3601 to the range 10 AFR to 20 AFR inclusive.

Same here, on my file it tells me the B3601 is out of range now, but still shows 10.00 If i try to change it to 9.50 it reverts right back to 10.00

Mmm ok, sorry guys it'll have to wait until Paul is back on board in a week or two when he can look and see what V7 is doing with the box enabled/disabled.

No worries.

No problem. Thank you :)
