ahhh..great to hear

but in my case it still didn't work i tried a different map with an older version of kmanager same problem still existing. i didn't have any problem before about 2 months ago. so even after i changed back the kmanager as well as uploading an older map it seems like the new one somehow just changed everything else.

First, do not backdate the software. That will cause problems.

Second, follow the posting guidelines and provide the calibration and a datalog.

Most problems after an update can be cured by clearing security and uploading the calibration again:
- Start by shutting down KManager and switching off the ignition & removing the key.
- Load KManager. Switch on the ignition. Select 'Erase ECU'.
- Shut down KManager. Remove the key.
- Repeat the above two steps again.
- Start KManager. Load your calibration. Check that the tables look ok and then parameters look normal.
- Upload to the ECU. Make sure that it uploads successfully.
- Switch off the ignition & remove the key.
- Switch on the ignition, start datalogging. If if will not datalog, stop. Don't try to start the engine. Find out what that problem is first.
- Start the engine.

i followed the steps..

result:
-datalogging was displaying or sensors were reading live in the display window.
-started the car, cranked and started for less than 1 sec then died.
-cranked it 2nd time, the same
-cranked it third time, it started, but a rough starting and it was idling
-at this point the kpro stopped displaying any live feed
-shut the car off and tried to start it again but did not start and back at the same problem again.
-repeated the steps again and no matter what nothing is helping.

Sorry, I put the steps in the wrong order. Start by following the posting guidelines, telling us what vehicle you have and providing a calibration and datalog.
