Hondata

ok i did somthing like set the security and now the car wont start and i can not upload to the k-pro.how do i undo this>>>>

Clear security and upload a new calibration.

and if that won't work what next. is there a way to sent it to hondata to have them reset it?

First, give us more information - what vehicle, ecu, engine swap etc.

1. Make sure you have the lastest version of KManager (1-2-0-2)
2. Switch the ignition on and use the clear security function. Switch ignition off, wait a few minutes. If you get any failure messages clearing security, go no further and try again.
3. Upload a calibration, making sure the immobilizer function is switched off.

If you have any error messages or something doesn't work, then tell us which step above fails and what any error messages are.

i have a 2003 civic si. i have the k-pro full tune. when i tryed that it worked the first tome but as soon as i want to upload sone changes it died and would now start again. but i will try it in the order that you have posted and see if that works. thank you
