Superchips JK Shift Schedule

I tuned my rig over the weekend with the Superchips 3870 Flashpaq. I have to say that I was skeptical at first but I was pleasantly surprised by how well it worked!

I purchased the advanced transmission tune but I'm not sure how it works and I want to have a better understanding before I start playing with it.

Has anyone tuned their tranny? SC won't give me much info, they just told me to "search the forums to see what other guys are doing". I did a search on here and other forums including SC's and I was only able to find one schedule.

Does anyone have a schedule available or can you point me in the right direction...

Thanks!

Hmm. This interests me as well. We have been running Flashpaqs on 2 Jeeps for the last few years and have yet to find enough solid info for tuning the transmission.

I run the Flashpaq's TOW tune, Jeep drives better with that than the other tunes except maybe the preformance tune which requires high test gas. with req. gas I get 15 mpg in town and 17.5 on highway.

Unfortunately the "Tow Tune" is telling me it requires 91 octane. Which I don't even understand why they'd have something that requires 91 octane. Here in NY we have 87, 89 & 93. And there's no way I'm shelling out $4.50 a gallon for 93!

The information I've found doesn't even jive with my vehicle. The throttle positions are way off from what I have. From what I understand, unless your vehicle is identical (i.e. year, gears and tire size) to a person who already did a shift schedule, the information is useless.

50% 89 and 50% 93 is roughly 91
