i got my car tuned. runs fine. i came home uplaoded smanager on my laptopn then hooked up the usb to make some changes to my launch control and boost control. but i cant make anychanges all the options are just invisible is there a certain procedure to follow before i can tinker with my settings?

 

I recommend you contact your tuner & ask the tuner to email you the original tune calibration.

Otherwise you can connect to the ecu by connecting the usb cable to the laptop/ecu, turning the ignition key on & clicking online then download.

 

thanks for ur reply. but will that erase my tune or just give me the ability to modify it?

 

As mtber mentioned
->connect to the ecu via usb cable to the laptop -> key to ignition position -> Smanager -> online -> download.

Then "save as" whatever file u want, so that u can revert back to the settings done by your tuner in case u screw up.

After which, u can start modify the settings u want and upload (Online->upload)
