The advanced options aren't going to create more power. As for the tune to use, I would say it greatly depends on what you are going to do. My guess is where you are and what you'll likely be doing, sand and higher rpms, the 93 tune is the one to roll with. In situations where more power is required at lower rpms the Tow tune is a great fit.

Also, if you tend to run hot in your environment, a 180 thermostat might be in order and reducing the fan on temperature to 200 degrees. Do not reduce your fan on temperature below 20 degrees above your thermostat. This will cause some CELs and open fan relay DTCs.

 

Reduced my tire diameter from 33" to 32.5" on my 315/75/16's (35's) and theyre spot on with my GPS.

Gas prices have dipped below $3 for 93 so after running about 5 tankfulls on 87, I switched over to the 91 tune and I can see a slight improvement in performance and economy over the 87 tune, but it's a small difference when compared with the 87 tune versus stock.

I'm on my second tank of 93 and will be switching over to the 93 tune for the drive home.

 

Clarify please....

 

With the flashpaq, you can adjust the temps that the electric fan cuts on/off at. Don't adjust it so that there is less than a 20* variance between the cut on point and your thermostat temp.

 

Thanks Bud! Now does the JK come with the 200* Thermostat stock?

 

Anyone running 285/70/17 Km2's with the Flashpaq? If so what are you setting your tire size to? Set mine to 32.5" does that sound correct?

 

The JK comes stock with a 195 degree thermostat.

A word of caution on this. If you live somewhere where there are changing temperatures/seasons you'll need to be changing your thermostat twice a year. If you aren't willing to do that, moving to a 180 degree thermostat is a really bad idea.

 

CRAP!!! lol so i got my SC today (kudos to Northridge4x4 for havin it here in 3 days)....update it online, hook it up to the jeep...2010 not supported??? I didn't even think about this when i bought it. Am i the first 2010 guy to attempt it? Too late to call them today, but i'll try tomorrow if i get time.

 

It would *seem* like the ECM calibrator cares about actual tire diameter not nominal, unless it has only limited settings.

I have a new ProCal and the instructions say to measure the installed tire height. Is not the same for the Flashpaq?

I am considering replacing my unit with a Flashpaq because of the extended functionality.

 

In cooler weather if you are running a 180 degree thermostat it may open causing your engine to begin to cycle some heat never allowing it to get to an appropriate operating temperature. This will not be enough temperature to evaporate moisture from the crank case, causing oil sludging. Also, not reaching operating temperature will cause poor fuel mileage, much like the claims you'll see of winter gas causing mileage issues when in actuality it is just taking longer to reach operating temperatures.
