I want to get a tune from mellon. I might not be able to drive up there, so I think I am going to send him a log for an e-tune. Will my car log everything? Or do I need a special wideband? I have a PLX wideband, but to my understanding, this does not log. Im new to this, so no mean responses, please.

 

From one noob to another......

There is a sticky about how to tune.... Start there and I am sure Mellon will tell you what to log....

The search button is your friend

 

I don't know anything about this wideband, but you most likely will need to log A/F. If you search, there is a thread explaining how to connect your wideband to evoscan. You need a serial to usb cable.

 

I use a PLX wideband. I feed the 5v wideband output into the ECU's rear O2 and log it. I cut the harness and added spade connectors and it works fine. Only when I'm logging do I have the wideband connected. For daily driving, I reach under there, disconnect the wideband and reconnect the stock rear O2 sensor. If I leave the wideband connected it will trip a check engine light for rear O2 high voltage. When logging it shows raw voltage, but I like to look at my data in spreadsheets anyways so in the columns I add the formula;
voltage x 2 + 10 = AFR
It works just fine.

I'd agree on reading the sticky on how to tune, but Chris will hook you up with excellent communication on what he's modifying in the maps.
