Close all the windows in KManager and try again.

There is nothing more you can do. You'll have to go to File, New and create a new base calibration.

I figured i might have to do that. Thanks for the help though. I talked to my uncle who set it up when we put it in the car and he thinks he saved it on his laptop so were gonna see.

i get it too .. there seems to be a bug in the software when it converts between lambda and air fuel in some maps

try this:
open any base map
in the menus.. Options->Settings->Units
switch the Lambda Unit
close map
re-open your map

you might get a bunch of access violations .. kill the program and restart it

Ought to be a sticky

Post by Roadrace »

I had the same floating point division by zero when trying to read a older S300 with new SManager. There's enough of these complaints that this ought to be a sticky until the Smanager is revised to prevent it.

I'm new to this tool, thanks for the great forum


try this:
open any base map
in the menus.. Options->Settings->Units
switch the Lambda Unit
close map
re-open your map

Its happening to me also when trying to create an A/F gauge in displays.

Now when I open Smanager reguardless of the configuation loaded I cant even open the display tab

I click the display tab once and I get the floating point error then everytime I click the display tab after that, I get "cannot open file error"

Guess its time to re-install Smanager.

reinstalling won't get rid of it. open the Smanager windows explorer folder. Delete "default.display". Re-open the program and all should be working.

See this thread viewtopic.php?t=7811
thank you, thank you, I'm here all week

Yea I ran into this too, just have to delete the "default.display" file as Josh said. Wish this bug would be fixed somehow 'cause it really wastes a lot of time if you had other display items setup then added the AF on later.

I made sure after it happened the first time to save my own copy of the display file and just save it often when modifying your display.
