Are there any related problems to this. i currently am have a issues with aem wideband cutting out randomly above 7k rpms wired on analog 0. I replaced gauge and sensor same issue rewired power and grounded to kpro analog ground still the same. Should I wire to analog 7

Here is the datalog

set it to raw voltage so that we can see the actual voltage that the wideband is sending.

lots of problems with kmanager lately, due to these issues i ended up switching to linkecu thinking my kprov4 ecu was faulty, but i keep running into the same problem on customers cars. its impossible to have a consistent idle afrs, 0 cam table isnt taking the changes made with live tuning off and even reuploading the cal but once i ctrl-z to undo, the changes quickly take effect and then next upload those changes are lost again. this is very difficult for me to explain but if this isnt fixed quick enough you guys may lose market share, live tuning is also riddle with bugs and not consistent. i noticed that using fuel compensation table for idle and low load helped settle the idle with closed loop disabled and the changes made to that table did take effect but every where else is affected negatively, im having to come up with new strategies to achieve a well rounded and dialed tunes but it takes a huge amount of time from me figuring out a work around these bugs. noticed this gets worst with bigger injectors 2200cc, please look into this. i have no such problems when tuning flashpro vehicles with similar setups and big injectors. also these bugs are not exclusive to the latest version but have noticed them getting absolutely worse.

This is the first report of this type of problem we have received. The ECU code has not changed since Sept 2022. Can you be more specific with what dates and versions you started to see this behavior?

Can you do something about the option to turn on the electric fan so that it stays on at least until the temperature drops 4°? I have it set to turn on at 90°, drop 1°, and then turn off the fan.
It would be very beneficial and important for high-cr engines to be able to maintain a good temperature.
Can they do something in the next update?

This has been going on for a while, i mentioned this on my tuning instagram page and a few people mentioned having these weird inconsistencies with kpro. One mentioned things getting bad post version 4.4.4.

Not sure if Kpro is unable to control idle, ignition based with a correctly calibrated throttle body given the settings are there but seems like it is unable to retard timing to settle the idle speed.

Another, i was able to tune around the bugs of tables not taking effect by not relying on live tuning or closed loop and every single upload, turning the car completely off and on again.

4.4.4 is 6 years old. If there is behavior which you believe is a bug then give the specifics here and we can test. I would suggest first starting with one specific example which is easy to test.
