I've used 4H PT during the Bantam Jeep Festival in PA back in June, for their blue trail. Lots of ups and downs but mainly dirt road. It handled extremely well, and I think the 4H PT should be used for trails like this, with front sway bar disconnected as well. I also used 4H PT in rainy conditions on the highway for extra traction.
I had asked earlier since I was a bit confused too, and below is what you replied. I don't think 4H PT will slip back to 20/80... Where did you read this or any official information to confirm?
Also, the 392 has a Select-Trac transfer case, not a Quadra-trac II. The select trac HAS part time (since 1983, as I eluded to), the Quadra-trac II does not.
A tech on the JL Wrangler site hooked up a recorder to the obd2 and logged the signals to the transfer case. 4H was much closer to 50/50 most of the time vs 4P, but it was not Locked at 50/50 . Throttle Position had more influence on the Locked percentage than actual wheel slippage....slippage did contribute and was an adder. 4L was 100% 50/50 Locked at all throttle positions. You can do a search over there and read the article. Very technical and helpful. I did not save it.
My comment is based on 4H part time‘s “intent” to be 50/50. It is not trying to slip. Programming will slip 4H PT away from the front based on throttle, as @onfire392 indicates. @onfire392 is a little backwards. 4H auto wants to be RWD and 4H PT wants to be 50/50. Programming slips it from those. 4H PT will stay 50/50 unless you push it harder then it will slip away from the front.
That is marketing. The 392 has a MP3022 and the WK2 has a MP3023. Marketing and programming is the only difference between the 2. Physically they are identical. I should know, I have one of each in my garage.
Definitely that is what 4H PT “should” do. But believe me or not, doesn’t matter to me, it is not 50/50 all the time. I have seen the sensor readings on my 392 on JScan myself. In 4H PT the torque numbers are not 50/50 all the time, after 30% throttle they diverge . In 4L they definitely are the same all the time.
Definitely wearing the clutches in 4P Offroad. Jeep could fix it with a simple programming change to lock 4P like 4L. Crazy that 4P does not lock. It’s much better than 4A , but not locked.
4H PT is the correct setting. But it will be more wear on the clutches than 4L. But a lot less than 4H auto. And if you are not “hot rodding” in 4H pt you will stay 50/50. But heavy use of the skinny pedal will slip the front.
I would buy a tazer if they could do the 4H pt 50/50 lock…. Don’t know if Joe is listening, but Z auto could sell a bunch of tazers if you added a 50/50 lock mode.
That's a Big 10-4
If you are saying it doesn’t makes sense that it doesn’t lock 50/50 in 4H PT, I think that everyone agrees with you. If you are saying that it doesn’t lock 50/50 in 4H PT, sorry that is wrong. It definitely doesn’t lock. Well I will say that my 2 mp3022/3 don’t and the person with the 4xe that posted pics of it not locking from the link thread from @onfire392 . So maybe those are exceptions…. But 100% my 392 and JGC with the same t-case both do not lock 50/50 in anything other than 4L. I have seen the numbers on my JScan for both. And they don’t lock 50/50…. But those are the only Jeeps I have personally witnessed the slipping of clutches…. So maybe there are only 3 and all the others lock…
