Would have posted in cax forum but didn't see any recent activity. Please move as required.
Just updated to V7.5.7.233 and the .cax calibration address are now overlapping. I tried a fresh .cax and cal_link file. Any help would be appreciated.

B9000
B9003

Yes there was changes to .cax file handling.
The first change was to check that *.cax definitions did not overlap with any existing EFILive calibrations. If a *.cax file has been set up so that it does overlap, then the final data that is written to the file is not necessarily what you would expect. That is because both calibrations will write to the file. The order in which they write to the file is non-deterministic, so it could be that you end up changing your user defined calibration's value which gets written to the file, then the built in EFILive calibration's value (which occupies the same memory location) gets written to the same memory location, overwriting the changes you thought you had made. If/when that happens it gets very frustrating very quickly if you don't realize what's happening.
The second change we made was to prevent calibrations being defined in the OS memory area. A mistyped address in a *.cax file can wreak havoc to an engine controller if the OS software is changed accidentally. The ECM's built in CRC corruption detection would not catch the problem because when saving the file (after the accidental OS change) EFILive updates the OS checksum so the ECM would never know it had a corrupt OS resulting in a bricked ECM. Note, the OS restriction does not apply the LS1B PCM.

Thanks Ross. That is interesting about how it works but a bit over my head. I would sometimes see B9021 get reset back to its default value after a write so I would just check it every time. So now I think I understand why it did that.
With the new changes in the .cax file handling, will I still be able to modify the hidden parameters? I really need the transient fueling tables, not so much the lean cruise but it came with the file joecar wrote.
Thanks,
Jesse
B9021 should be ok with 12212156/02020003/02020005.
Thinking about it, it would be better if B9021 was predefined rather than 3rd-party cax-defined
Hey Joe, so I was just looking over my 02020005.cax file and noticed that the addresses for B9014 and B9021 are the same, (B632). Also my cal_link link file does not have B9013 and B9021. What does the cal link file do?
Here is what I have:
{B9001} Stomp Make Up Fuel
{B9002} Impact Factor Modifier
{B9004} Boiling Time Modifier
{B9005} Wall Mass Factor
{B9008} DFCO Stomp Compensation TPS Min
{B9009} Stomp Compensation Delta Low Limit
{B9010} Stomp Compensation Delta Limit
{B9013} Stomp Compensation Delay
{B9014} Minimum Stomp Fuel
{B9100} Lean Cruise Enable
Here is the cax I was using and B9021 worked ok.

When I had B9021, it would be located just below B4006 under fuel/injectors/parameters. I have attached my .cax and cal_link files in the first post. Please let me know if you see something obvious. I will try just the .cax b (just B9021) that Mick posted and report back.
UPDATE:
Loaded cax b and B9021 is working now but don't have the others.
This new handling brought some issues with a couple of CAX files that I have....... Is there a way we can disable this check?
what controller?Quote:
