I'm upgrading to 305x70x17 tires next week. I plan on getting Superchips Flashpac to tune 2013 JKU Rubicon. Can I reset shift points using Flashpac?
Thanks

 

Yes, you can input the tire size and it will adjust the tune for you I did this when I went up to 35s it allows adjustment for any tire size. When the tires and wheels get put on get an actual measurement and adjust for the actual size

 

I recently installed some mods on my 2014 Wrangler Sport and I have a tech question. But first, a long winded explanation.

I first installed the 91 Performance tune prior to making any other mods. Love the tune as it feels much more responsive. Then, I installed a K&N CAI and a Magnaflow Axle-Back exhaust. When installing the CAI, I broke the IAT sensor and replaced it with a new sensor. My Jeep now seems to be not as responsive as it was before the mods.
Question: Do i need to re-load the Superchip 3872 Tune?
Help!!

 

Disconnect your battery so your ECU can learn the new mods then reinstall the tune.

 

Thankyou. I will try that. Just so I'm clear on the instructions...Do I need to revert back to stock first (after I reconnect the battery of course) and then reinstall the tune, or should I simply reinstall the same tune?

 

Ya I guess it wouldn't hurt. Good luck let me know how it goes.

 

Not that this will help but when researching exhausts for my 2010 3.8L on Amazon I came across some one with a 3.6L that had the same problem as you. Turned out for this guy if running a CAI with an exhaust it's actually to free flowing and to get the response back you have to change resonators. Of course this was running the Gibson exhaust but the manufacture states not to run the exhaust with a CIA in the 3.6L. Something else to consider perhaps if the flashbacks reprogram still doesn't work.
