s300 Firmware on a p72 ecu launch control

Hi, I have just downloaded the latest Smanager software and it prompted me up update my s300 p72's firmware before uploading my settings,

The engine does not seem to run the same as it was using the old firmware air fuel ratio is different at idle or driving etc. and the Launch controll cant be turned off, this was on the air con switch and worked fine on the old firmware, I have checked the settings out and its correct in Smanager.

Are these known problems? can I use setting files made with older Smanager software in the latest version?

Thanks

There are no known issues with this. Try closing the program, reopening it then loading your calibration and uploading it. If you have been downloading the calibration from the ecu then uploading it back, this may be the cause of the problem you are describing and the calibration may be corrupt.

Hi, I have now uploaded to the ECU using an older version of Smanager and the engine runs normally, but since I updated the ECU firmware the Launch control still does not work on the air con switch (cant turn it off) I have checked the settings, inverted the input etc.

The calibration was from my computer, not downloaded from the ECU, any ideas how to get this working again, is it possible to go to the previous firmware version and try that?

Thanks for your help,
Mat

I tested this using the latest version of software and have found no problems. Post the calibration and a datalog showing the problem.
