sct 2 question

[wolfstang03]

does the sct x cal 2 turn off the pesty engine light?

 

[Quick281]

engine light = problem. need to get it looked at

 

[wolfstang03]

no i dont have it on.. just when i want to put a non- catted h pipe on... i dont want the engine light on.

 

[Quick281]

02 sims are the only way to keep it off

You should be able to turn the rear o2's off with the Xcal 2. I know you can with the older Predators and the Sniper as well.

You can turn off the rear o2's with the x-cal 3, but I don't know about the x-2 tuner. You can read codes with the X-3.

You cannot turn off the rear O2's with the xcal2 alone. It must me done in the tune. You will have to have your tuner do it.

I would rather have them tuned off than using MIL eliminators. If you do get MIL eliminators, I would recommend the plug in type as opposed to the splice. If you do splice them though, make sure you do it toward the plug end of the harness. If you splice too close to the sensor, you risk damaging the sensor, as the insulation in the harness contains a "channel" the sensor uses for air reference.

I think the only one that you can shut off rear o2s without a custom tune now is the Sniper. Diablo doesn't allow it anymore. They used to have EGR and secondary o2 selections that you could shut off.

Edit..maybe with the Xcal 3 you can. It's misleading online if you search because it shows the option of rear o2's being shut off with the Xcal 2, but it may mean with a custom tune on the xcal 2.

having the o2s turned off in the tune wont let the car pass inspection. it wont set all the readiness monitors. i had to have mine turned back on. after that the light would come on every 100 miles or so. i bumped the timing 2 degrees and its stayed off since. :idk:

I tuned them out on my friend Mach 1 and it passed ok?

 

[Quick281]

mine wouldnt set the monitors. never tripped a light, but the monitors wouldnt set so it wouldnt pass nysi

 

[wolfstang03]

im getting the sct xcal2 today... should i run the 91 octaine out of the tank if im gonna tune it for 93? or just add the 93?.... its at half tank now

 

[jrmandryck]

Obviously running the 91 out is the best idea, but it won't make a huge difference unless your new tune is bumping the timing advance up

 

[Quick281]

ive had to run 91 on a 93 tune. it really doesnt make much of a difference unless you are pounding the car

Yes it will pass, if it's written into the tune. The computer "thinks" the O2 are not even there..........so it has no idea anything is wrong.

 

[Quick281]

if your tune turns off the rear o2's, it will NOT pass. just went thru this with my car, and matt did as well. the o2 readiness monitors will not set, and it will not pass emissions.

What year is your friend's car?

Because every newedge owner I know, had the o2's off from the tune, and passed emissions, successfully.

I tuned them out on my friend Mach 1 and it passed ok?

x2.....every pre-s197 (most notabley newedge models) owners I know had their o2s off from the x-cal (with the tune) and had no issues with passing emissions inspections. I know Ford made the computers a bit more "smarter" with the S-197, partcularly with mods....for all I know, this may be an S-197 issue? I never seen this as a problem for newedge cars.

I have no knowledge of the 05 and newer cars. The 04 and older will pass as stated before.
