Warning!!!!! Kmanager version 4.2.0 and Kpro filmware version 4.2.0
If you have updated to kmanager 4.2.0, uploaded k20a3 map and having problems, all you need to do is update to 4.2.3 BETA and make sure you keep your older kal.
I ran into problems with 4.2.0 and kal generated by this version. The symptoms are:
1. Hard to crank
2. Car started with high idle (2K+) and CEL
3. CEL cannot pull a code or CEL with Daughter Board Communication Error code
4. Limp mode
5. Ran datalog at kmanager but not reading one single data
6. ECU tickled a few times during power on
My combo to solve this issue was:
Kmanager version 4.2.3 with Kpro version 4.2.0 filmware, uploaded kal that was generated by kmanager 4.1.5. MAKE SURE YOU KEEP A COPY OF OLD KAL AND DO NOT USE 4.2.0 KAL!
