It happens between about 1,700 and 2,200 RPM. That stinks because that's where you usually end up right after a shift.

I'm convinced it's not the electronic throttle and the Superchips does not resolve the problem. When you experience the hesitation you can hear the engine noise increase (which wouldn't happen if the throttle was lagging). It hesitates for about a second and then takes off.

For some reason it doesn't always hesitate and I notice it much more in hot weather.

I started data logging with my flashpaq to see if I could figure out what causes it. I noticed when it occurs the spark advance drops super low. In fact it goes negative (retarded timing). You see the timing go to something like -3.0 degrees and then finally shoot back up to 20 - 30 degrees. The increase back to 20 - 30 degrees of advance coincides with where the hesitation ends and the jeep takes off.

So then I thought maybe it was a knock event causing the computer to pull so much timing. So I started watching the knock sensors. I didn't see anything abnormal there, so I don't think it's a knock event causing the huge reduction in timing.

I sent Scott from Superchip an email about this. I'm hoping their engineers can look at it next time they have a JK on the dyno.

I've heard tons of 6 speed owners complain about this. So if you're one of them who experiences it please chime in. Specifically I'm interested to find out if it's just the 2007 and 2008 owners that have this issue or if people with newer jeeps are still experiencing it. I'm wondering if Chrylser at some point fixed this and maybe a reflash from the dealer will resolve it.

i have an 08 rubi AUTOMATIC and i drive around in 2nd around town and i have noticed when slowing down for turns or more so at stop lights going into turns throttle on it shifts from 1st to second and without throttle change on my part after second engages it lags for a sec then instantly jumps a bit on the rpm and starts going again almost exactly like what you are describing with shifts on the 6 speeds - i have only noticed this about 3 times so for but its something im really looking for now

and this does not seem like gear changes or slippage or anything of that sort the trans feels like it is functioning perfect it shifts from first and it feels like the paks and everything are fully engaged - maybe its timing maybe its stupid computer junk and it is probably something completely diff as this is the auto but it sounds very similar

maybe im just off and this is how this thing works but i just started noticing it after 2 years and 25000 miles

hmmmmmmmmmmmmmmmmmmmmm
