First Road Trip!

I just got back from my first real road-trip in my Jeep. I went to visit/camp with my former roommate and some other friends on my property up in NW Arkansas, near Rogers. I came from Shreveport, LA. The distance there was about 400 miles each way. On the way up, I filled the tank when I left Shreveport. I got 18.5mpg figured by hand and the information read-out matched it. On my way back, I got 18.9mpg figured by hand, and the information read-out was showing 18.6.

Observations:

Very good road-trip vehicle. With the Bilsteins, it was confident even on the sharp and hard corners near my land.
The ride was very comfortable and I did not feel "punch drunk" like when I road-tripped in my 370Z and other vehicles with louder exhausts.

The V8 had miles of torque. Very pleased. However, I ran into a few annoyances with it. At first, I thought the tq converter was chattering/shuddering, but now, I feel that maybe the misers who programmed the vehicle did so for flat-land performance. The symptom was when in cruise-control, or when gently rolling onto the throttle, while going up a slight incline or starting a hill, the Fuel Saver would first shut off and the RPM's would drop a few hundred, then the exhaust tone would become very labored and the entire Jeep would vibrate for a split second before the converter unlocked and it accelerated. At first I suspected a transmission issue, but to me, for all the world it sounds like the ECU is programmed to lug the engine just a tiny bit in some cases before unlocking the converter. Thoughts? Anyway, it returned good mileage...

Otherwise, the Jeep was quirk-free.

Over-all, the Jeep did what I needed. Handling was excellent, acceleration was adequate, and I did not have any issues navigating muddy gravel areas on steep hills.

Re: First Road Trip!

good to hear that you trip went well. Nice rifles BTW. to me it sounds like MDS transition at partial throttle tip in.

Re: First Road Trip!

Thanks!

I'm using ddm4 with t1 and surefire 556-212a. Former roommate with his bcm and my m4s and sf can.

Would mds tip in vibrate entire vehicle and cause rpm to bounce 100 rpm up and down ?

it's possible as the hemi is running in 4cyl mode. im sure someone with a hemi can chime in, but I think I read somewhere on here of a vibe with MDS transition under certain circumstances
