X-CAL help

tacatc · 11-06-2006, 05:33 PM

Well my CAI and X-Cal was waiting at the door when I got home today. I'm getting ready to install and tune but I have a question. The X-cal instructions say to disconnect the fuel pump and eletric fan fuses. I haven't heard anyone talk about this before and the directions don't say when to reconnect them. This is the first time I have used one of these so I want to make sure I get it right. Did anybody else disconnect the fuses before flashing their computers? If so where are the fuses located and when do you reconnect them?

Reconnect fuses when the xcal is done installing the tune .....

Ok so I do need to disconnect them. Now which ones are they, are they listed in the owners manual?

yep, sorry I don't have mine handy but they are in the engine compartment passanger side beside the computer unit...... square fuses.... your manual will list them....

They do that so there is not spike on voltage that can screw your car computer..... just precaucionary..... I always do it....

Good luck!!

haha i never do it the x cal tells me to turn the key to the power position only when im installing the tune
i think this is the safety feature for the power

I know, but better safe than sorry.....It only takes 10 seconds....

I don't unplug mine either, I've heard they want you to take out the fuses in case your battery is low, I guess it could cause your battery to die. There is 2 big fuses and 1 small one. I used to but not anymore.
