Thanks for the response, but the online store wont let me "buy" the TPMS package because apparently it is already updated. I also don't think I have an 87 tune option??? I think just 87 octane?? That isn't the same right? 87 octane is just to get a vehicle requiring 91 octane to be able to use 87 octane I thought?? I'll hook it up and look again to make sure....

Ugh I didn't think this process would be this involved

 

The 87 (whatever) is the same tune. It's designed to get a little more power out of regular gas.

As for TPMS you have to call SC. They will email you a release form, you have to email them back with "I agree". Your SC serial number and then they well update your programmer. I would also have them add the trans temp file. That way you can see your temp.

 

Great feedback thanks!

 

Yes that is correct, and that is why the relearn feature has been shelved for the moment until we move towards creating a Trail Jammer EXT performance kit for the JK's like we now have for the TJ's. We can then provide a custom tune that works with a Superchips branded big bore throttle body and CAI kit as a complete performance package.

does this chip leave a foot print and void your warranty from the factory

 

As long as you get 50+ miles on after setting back to stock there is no footprint. From my understanding there just isn't the storage for it but you need to get the miles in to overwrite the free space. If you return to stock in the parking lot and then roll into the dealer's garage, they'll be able to see a footprint.

Also, this isn't all that big of a deal as the service techs in large look the other way. Many of them have tuners on their personal vehicles and don't care one way or the other. Diesel vehicles are quite different and those definitely warrant a closer look. Like anything else, don't get into a pissing match with them and everything will be OK. Also take the time rolling stock before taking your vehicle in to rebuild the learned data. If they look and it's totally clean, of course they're going to know what time it is.

 

So for those of us in the Mountain states, that can't get 87 octane. Is there any downside to running these tunes at the 85/86 octane level that we buy. Or will I be forced to run higher (more expensive) gas.

Thanks,

With the 87 tune, you will be better off going with the next highest octane available. Running less than 87 octane with that tune will more than likely cause detonation due to the advanced timing

 

The same rules apply for a Flashpaq that do for the octane ratings available in the mountain states. Without any complicated formula, every 2500' above sea level you are you can drop 1 point of octane because of the thinner air. I'd still start out a bit conservatively using a higher octane and then try to make some multiple trips to refill after burning a quarter tank or so until the re-learn process starts to take hold.

Also, what Octane ratings do you have available? For efficiency/value in the summer months I run the 91 tune with 91 octane. You might be able to find the same successes I've had running 89 on the 91 tune and more than worth it for the extra dime a gallon.

 

We generally have 86,88, & 91. I think I understand what you are saying, although I am not sure the higher octane is truly the best value, unless you also include any performance benefit. Just straight mpg per cost I don't see the benefit of the extra octane. I have decided on the super chips instead of the other options, although the new android based tuners look cool.
Jpop I'll try your suggestions and see what happens.

Thanks,
