Today I got left on the side of the road (in the rain no less) - Sequence of events -- yesterday I got a new MF cat back exhaust and wanted to take some video. I did two runs in map2 (the truck has been in map2 constantly) and then I switched the CAT6 to map3 (for the 2nd time ever) -- then the truck literally stopped a minute later -- no throttle response whatsoever, although it's running (idle) just fine. I let it sit, switched back to map2, and then stock. I unplugged all CAT6 connections under the hood and dash (in the rain) and reconnected --- I disconnected the positive side of the battery -- no matter what I tried I got the same error messages (attached). I ended up calling Ram roadside assistance --- while they were on the way I fully removed the CAT6 system (not fun in the rain with way too many added zip ties) -- packed up all my personal things and sat waiting for the tow. When the tow arrived 20 min later, I started the truck -- and wouldn't you know it -- it revs. All warning lights on the dash also cleared. I drove the truck home with no further issue. (note my truck has just 1,100 miles on it)
So, I'm guessing this is a repeat issue now with my CAT6 -- the second time being much worse than the first loss of power but still moving (which has repeated 3x now). I'm unsure if the CAT6 has a program issue (its software is up to date), the truck does -- or both.... but it does seem like it's tied to the CAT6.
Anway, I just now hit 1000 miles arriving home....on the last leg of the ride back home, I did two launches with the CAT6 on map 2 (in fact I did the entire 7 hr trip on map 2) -- using 3700 rpm as the launch set point. The first I got some traction control flashing, but still got a 4.50, the second I got the exact same 4.50 (on the performace page) with what I felt was a better launch. Either way, it's a fast 6,300 pound truck -- I didn't try map 3 for launch yet, maybe next time. Vehicle was 2/3 full fuel with 1 passenger and in sport mode. No complaints! It was the most comfortable road trip I've had in a long while -- power, peformance, and comfort (and let's not forget level 2 autonomous driving (it's reeeeealy freaking good!) Cheers.
