First thing is I bought a 2003 Cobra and was told the Predator with the MAFia was used for tuning the car. Now the previous owners installed a ported eaton blower with a 2.93 pulley and 4lb lower pulley. My question is when I plug the tuner in the car is off it tells me to cycle the accessories on which I did and reads some trouble codes. No biggie on those. My question is do I need the a/c adapter to update the tune? I was interested in seeing more of what the options are with this tuner. Can I add more fuel pressure etc,? I didnt receive a manual or a cord so I bought a serial to USB cord. This is my first time using a handheld tuner. So any help is GREATLY appreciated!

The manual is available for download. Just follow the links from the support tab above.

When you go onto our website. Go to support/downloads. Put in your part # which is u7142. Go all the way to the bottom of the screen under documentation. You will see the manual there that go can download.

Ok I have the manual how do I know if there is a tune on the car or if the previous owner did anything? Also where can I get a plug so I can power it up not attached to the car? There looks to be a plug in for a/c power..

Go to options/show last tune written. That will tell you what the last tune was written to your vehicle. You can purchase a power adapter to power your predator up from Radio Shack,Best Buy or Circuit City. It's 12v 1amp Center pin positive.

Thank you so much for the help. Now when I see the last written tune can i bring it up on my laptop or can I just see what was changed on my handheld device and what the parameters were set too?
Thank you !
