I uploaded a custom tune from pcmforless and the fans come on when I start the car and run constantly. This was a program for an idle increase to compensate for a cam. The original pcmforless program was fine when i uploaded it 2 months ago. Why would this program for a simple idle increase cause this. No ses light either.

 

I think you'll get a better response in the computer/programming section.

Do you have a SES light? Usually a code thrown will cause fans to come on like that and stay on.

 

No ses.

 

Thanks, I posted it there too.

 

pull the pcm fuse under the hood for 30 seconds or so

does the car run?

 

Yes it runs fine. The PCM was reset after the upload.
