Thread: ODB 2 Tuning?

Hey Calum, my friend was saying that you can get your ECU tuned through the ODB 2 port? Is this true? I see how it COULD work but don't get how it would keep the readings. Obviously would have your base tune, but I'm talking like fine tuning.

I have a few places around me with dynos and they tune the cars but do you have to have a tuning device like a safc or can they use the port to do it? Also me having a wideband would be needed. Also which wide band would you recommend using? I was thinking
AEM UEGO

or
Innovative LC-1

No, pre-2000 Nissans still have a ROM based memory, so you can't make any permanent changes through the OBD-II port.

I really like the Innovate for tuning (I like their software), but the AEM looks the best if your installing it permanently in the car. Their gauge just looks slick.

ah ok, thanks for that info.

And for the gauge I want the best price but I want function. I think I found the AEM UEGO for 220 in Jegs. I like that the LC-1 has the the program fro data logging but I hate the small gauge.
