I just got my xcal 3. I havent put my supercharger and IC kit on yet but my check engine light is on right now due to my cats being removed. Can I still go ahead and use this thing on the car to turn that code off and at least give it one of those tunes it comes with? I plan on putting the SC on in like a month or less. Are these thing dummy proof?

[HMUSN]

you mean upload the canned tune ? unless the tunes is for the supercharger you can use it to get rid of your cel

[BakerFX4]

yeah can i use it as if i was never going to put a SC on it. Use the can tune and turn the check engine light off? when i put my SC on it will go get it Dyno tuned and save it to the xcal right? this is my 1st tuner EVER. i wish i could use it on my car and my f150 that needs to have the speedometer changed for the 36" tires. oh well. But i can just put the canned tune on it and turn that code off right? They hard to use? im half scared to take it out the packaging. haha.

[HMUSN]

it's very simple to use man.. and yes you can use the canned tune on it.

just plug it into your obd2 port, pull the fan fuse and fuel pump fuse then click about 4 buttons. it's childsplay

[BakerFX4]

on the packaging it say there is 3 different tunes i believe. which one should i choose? sorry to be so ignorant to this computer stuff.

[HMUSN]

they are octane tunes.. put the tune in that your car currently has gas in..
89/91/93 yada yada..

[BakerFX4]

Gas is only three thousand dollars a pint... better stick with the 87 as long as i can... the SC will change that before too long. Aight bro... will it tell me how to eliminate those o2 sensors from throwing the code all the time?

[HMUSN]

sure will if you bought the tuner that can change parameters.
fyi you won't see much of a gain with the 87 tune..

honestly.. I use the 93 .. I did the math and if you drive 15k a year you would only be spending an extra $75.00 per year on gas.

[BakerFX4]

Are you sure? only 75 bucks? im not really looking for power gains. I had to have it for the SC and all. I want to use it now at least for the check engine light to go off. What do you think of how gt's sound without cats?

[HMUSN]

well think about it.. premium is only $15-20 cents per gallon extra. it's an extra $3.00 per fill up. that's not much when you add it up. a GT sounds good with an off road pipe but will sound like ass with gutted cats

[BakerFX4]

where are the fuses you are talking about unplugging dash or underhood? then i just plug it up and go from there. There is no instructions at all.

[HMUSN]

they are in your fuse box under the hood of your car.
then you would just plug the tuner in

[BakerFX4]

aight bro stay on here... i might need your help.

[BakerFX4]

its been hung on Please wait for 10 min. or so. I pushed the wrong button and it said error and said please wait while disconnecting. Stuck there? can i just unplug it?

[HMUSN]

depends.. did it already save your stock tune?

[BakerFX4]

no... didnt get their yet. it said to scroll to vehicle and it was on mustang gt but i scrolled and hit select. Accident on the scroll button. it said error and now it says exiting please wait.

[HMUSN]

oh ok.. thats fine then.. you can unplug it.

[BakerFX4]

how do you turn the o2 censor off?

[HMUSN]

it would be in your menu if you had the option to do it (depends on the tuner you bought)

[BakerFX4]

it was in the menu but it wouldnt let me change it. it also wouldnt let me change the fuel type from premium fuel.
