how to use calcon?

Did you setup the payload on your .ccf file before you uploaded it? When you setup your tune, you gotta go the utilities tab in CalEdit, click the functions you want to log and hit 'Payload' to load the selection onto the file (the checkmarks will all dissapear, but it's okay). Then save the file and load it to the tweecer and try again.

Yeah what he says. Also, don't forget to save your payload.

Go the the EECtuning forum it has a section there where folks ask those same questions when they had installation isses. Do a search over there and I bet you will find the answer. It sort of sounds like you may have something mixed up with the computer file you are using. I know I had similar problem and what I found was that I accidentally changed the j4j1 at the bottom to A9l - it screwed everything up. With that in mind here's a tip on how to clear KAMs without having to disconnect the battery etc. Install a bad tune to one of the 4 positions - in my case I put A9l in my No. 4 position. When I load a new where there were changes to the MAF or TB airflow rates etc. I install the new tune then turn the dial to the bad tune - Wam, the KAMs are clear or computer is reset. Some peeps have used this method as the theft device. They would load it in the No. 1 position and remove the dial from the car. I would not suggest this method because if you lose the dial or it gets damaged, the TwEECer defaults to the No. 1 tune, which would be the bad tune and the car will not run.

Again check in the EECtuning forum under hardware install section. Have you check there yet?

Peace
