The directions how to turn it off start on page 375 in the owners manual but... I don't think that is your problem. The brake pressure is released in proportion to the amount of throttle you give it (page 373). The 3.8 motor has little or no low end torque and is easily killed if you don't give it a lot of throttle when taking off, flat ground included. I have a '08 and I kill mine frequently because I'm used to diesels.

Not sure what an old Baja racer has to do with anything? About 1% of their time I'd say is at a stop. And anyway I said 'if you don't find it nice to have off road'. I didn't say you couldn't off road without it, or shouldn't off road without it.

So whats the point of the historical lesson?

I have got an 09' auto does it have hill start assist?? It seems like it bogs down when I am in 2wd starting off on a hill.

No, manual trans only. Gearing is probably the problem, unless you are off road and your traction control is then your problem


Unless you are in 4-low or manually turn off the ESP (pushing the button only partially turns it off, completely off is listed in the owners manual) then the traction control will limit your wheel spin by using the brakes and reducing engine torque. I drive around with mine 100% off, so I drive it however I feel off road.

I think your right!!! but I could stand to regear as well, 35's with the 3.73's manageable but it leaves you wanting much more.

Sorry, but I have to disagree. The low end torque is good enough. the problem is the ESP program. It is the one that stops you from having low end power. If you pull the ESP fuse out, you will notice a huge difference in low end torque. the Superchip helps mitigate the effects of the ESP which is one of the reasons it is so popular.

So whats the point of the historical lesson?
He drove from Cali to the Panama Canal..... if you research it he is the ONLY person to do so, and it was in a STOCK CJ. His Jeep was on display at Camp Jeep 07 with a ton of photos from his jungle trek. So STOCK CJ, in the jungles of Panama, no lockers, no hill start assist, no lift or tires, no roads. Not alone, either, he led an expeditipon with full recovery gear. But if he could it then without all the do-dads.... See where i was going?
Dont get me wrong i am all for technology helping out off road. I was happy to see Jeep finally go to the BLD, after Landrover and Hmmer have been using it for decades. HSA, is a good thing, but to say you cant wheel hard without it is a little overboard.

"From the mid to late 1950s Chuchua continued to race his jeep and participate in club runs in Southern California. He rode as a member with The Chuckwalla Jeep Club. His Jeep was the first to climb the Devil’s Slide at Pismo Beach in the mid 1950s and in 1954 he participated in the Rubcion Jeep Jamboree. He also started to use his Jeep to explore further regions of the globe and in 1960 he drove his Jeep from La Habra, California through Mexico and Central America all the way to the Panama Canal"

Rubicon Trail...... Central America..... NOT ALL BAJA

the situation you are speaking of works if you stall the jeep but why would I turn off the jeep to start out????? when it is already running?
I can work a clutch just fine with out it but it is usefull if you learn to use it to your advantage. Kinda like the internet, you can ignore it or use it for good things to help you out even though you can get by with out it.
