Im driving from San Jose to San Diego tomorrow morning and my saleen isnt turning on. I am trying to swap out tuners. I am switching from a Livewire to an Xcal2. I returned the car back to stock on the Livewire, removed the livewire, downloaded the same tune onto the Xcal2, plugged in the Xcal2, and tried to install the tune. The Xcal2 tells me to turn the key to the ON position, when I do that the Xcal2 like doesnt read that the key is in the ON and eventually gives up and says that it timed out. Also when I turn the key to the ON position I get a **** load of warnings like check brakes, low fuel (when I have fuel), and some odometer error.

So then I decided to unplug the battery and maybe clear out some of the crap. When I plug it back in and try to turn the key on it gives me nothing. None of the dash guages turn on. Only the radio and accessory lights turn on. And the tuners wont turn on either.

Any ideas?

 

I just found a blown fuse in the passenger side fuse box. It was the gauge cluster and the obd2 port. I didnt have any spare fuses so I took the windshield wiper fuse and plugged it in there. I hooked up the xcal2 and it turned on. I turned the car to the start position and it immediately blew the fuse again.

 

Sorry I ono how to help good luck.

 

It sounds like your x-cal 2 is causing the problem, have you tried getting a new fuse form Ford and switching back to livewire?

 

Put a new fuse in and turn the ignition on w/o anything plugged into the OBD port. If the fuse doesn't blow then something is wrong with the xcal2. If it still blows then you have trouble.

 

Im going to get a couple fuses right now. In between using the two tuners I installed an O2 sensor that was never hooked up. I thought that might have been the problem because it could be shorting or something but I unhooked the O2 sensor with the second fuse I used and it still blew. I was also just packing some stuff in the trunk and noticed a wire had been disconnected from my BAP. That also could have been shorted. Ill try starting the car without the tuner hooked up and see what happens.

 

Seems like I've read about weak batteries causing that problem (blown fuses) as well when trying to use the tuners.
