wideband lambda conversion problem

hi to all!

everytime, when hondata brings a new update, there are more problems than before. maybe i´m the only one, but i do not think so.
the software was working well and almost stable, till i made the update yesterday. now, i cannot change the lambda conversion to match with my lc-1. i know, that hondata will say now " the innovate lc-1 is not good", but this time, it cannot be a problem with it.

the next thing is, that there are new points in the smanager, but not in the manual. so we users must search the new things, and try a lot, till we find out how it works. a lot of people tune the cars by themselve, so hondata should also update the manual!!
maybe one of you can help me with the lambda problem, cause everytime i change the values, they jump back to the same numbers as before.
thx, wolli.

now i tried something different:
i opened an older calibration file, changed nothing(!!), and saved it with a different name. and look at that: the lambda conversion values changes to something that no one can need!
i get silly with this shit! what are you doing at hondata?? i allways tell people, that hondata is great, but sometimes i really wonder!

what version were you on prior to the update? You may need to rebuild a new file.

that´s another bad joke. you have to make a new map much to often! but i tried to make one, and nothing changed. i´m not able to set the values in the conversion tables to what i want.
started the car in the morning to drive to work, and it´s running very lean at idle. and when i raise up the fuel tables, nothing changes. the car ran great on friday, with the old smanager. but now, it´s undriveable. i slowly get really angry about hondata.

@hondata: when you bring out a new update, please tell us, when the tuning maps are not compatible with the old calibrations!! and also how to handle the new options would be fine.

There should be no difference in the way your car runs when changeing from one version to a new version. The lambda conversion table will have no bearing on how your car runs as that is just a datalogged value. We are currently looking into the lambda part of the conversion tables as the A/F portion works perfectly.

the problem was, that the fuel ect compensation was wrong. the maximum was 65° celsius. so when my car was getting warm, it made a -50% correction. and that was the reason for running lean. and the same problem was with the a/f to lambda. i found an old thread, where another one had exactly the same problem. so i made a new map again today, and then it worked (at the 2nd try!). there is a big problem with different units in the software. i had to program with a/f and ° fahrenheit, then it worked. but when i try to set a/f back to lambda, i have the same problem again
