I am new to the forum, have had an e8 in my sti for some time and my tuner has been maintaining the setup on the car. Up until recently I have been having some issues with over heating on my temp gauges. Have changed thermostats etc but have recently found that the thermo fans are coming on to early and going for to long preventing the thermostat from opening. I know what I need to do to stop the problem but my question is how can I do this myself?
I still have the disc that came with the ecu from new and the plugs to plug into my computer but have never installed the disc or even considered doing anything myself. Is it simple and can I adjust the thermo fan settings quite easily?
I would take it back to my tuner but need to get a quick fix soon due to an upcoming event.
Help would greatly be appreciated.
