Re: ECU Tune

How are you going to apply this tune if someone gives you one? What you are asking is for some custom programming. Usually people pay for that. Yours stock tune should tell the fans to come on. I would suspect you have some other problem. More specifics about what the mechanic was seeing might help.

Re: ECU Tune

It's almost impossible for the PCM to simply forget something in it's tune. If the PCM isn't telling the fans to turn on, there is probably something amiss with the temp signal it's receiving or possibly even a wiring issue.

I know someone here had a link to a lot of tunes for our cars. Don't know who though.
