Hi. This is my first post to the forum, but have been lurking for a while and reading lots of past posts.
I bought a 2003 6.0L Excursion a couple of months ago, and I would like to do two things to start. (1) Add boost and EGT gauges, and (2) get a code reader. I'm really not interested in changing the PCM programming at this point because this is my wife's car, and it's essential that I don't void the warranty.
I started reading the posts and found that some of the tuners will give me digital gauges and the ability to read codes. This is appealing, but if I get a tuner, I have to be absolutely sure that it will never set a code in the PCM that the dealer could use to void my warranty.http://www.coolsmileys.net/angry/nono.gif
If I get a tuner, and never load a new flash, will it set a code in the PCM? It would be great if I could use it like this, as a monitor and code reader only.http://www.powerstroke.org/forum/ima...umb%5B1%5D.gif
