Question ECM Flash or Programmer

I've noticed (and read on other boards) that the '09 Ram 1500 is programmed to decelerate when shifting between 1st and 2nd gear. I guess it's a way to save fuel. Has anyone else noticed their trucking doing the same thing? Have you read or heard about having the ECM "flashed" or know of a programmer that can "correct" this?

As for programmers you are in for at least a year wait before you seen them.

it is to save driveline components, not fuel. One of the 'features' written into torque management.

It doesn't deccelerate. The pcm pull timing to decrease the power output during the shift. It also pulls timing when accelerating from a dead stop. It is really bad in the 09's.
The Hypertech tuner should be out very soon (I am beta testing one now), but, as of now, it doesn't do anything for torque management. Dave at B&G can get rid of it, but that involves sending your box to him, him programming it, and then sending it back. He tuned one of my boxes before and did a good job. The only problem with going that route is that if you ever take your truck in for warranty repair they will know it has been reprogrammed.
As a point of interest:
There is a hidden code now (p2000) that comes up when you flash your box. I am not sure how long it has been around, but I flashed my 2000 many many times and it never happened. Every time I flash the 09 with the hypertech it comes up. It is clearable, but does not illuminate the CEL.

Hey Mopowar, how does the tuner feel ? Details please ! I have had 3 new F150's in the past 5 years all custom dyno tuned, been to dyno days, and was a bit disappointed at the lack of any tuners frequenting the Dodge forums. These guys were great to have around and a wealth of knowledge. The throttle lag on these stockers is not nearly as bad as the Fords but a more aggressive 89 octane tune would be great. And definately not disable the MDS, I like this 18mpg average on the work commutes since this is used as a daily driver.

That is pretty sneaky. Maybe I'll have to check my 06, although the dealer never mentioned anything to me, but who knows if they would.

I don't know if this applies but I have noticed this truck is one of the worst vehicles for drag when you let off the gas that I have even had. Even my Durango R/T with 392's didn't make you feel like you put the brakes on when you let off the gas on the highway is where I notice it not in the city. 60 mph down to 40 in a few seconds, then it mellows.

thats pretty slick. ive never heard of or seen that code. probably a way of chrysler knowing that its been aftermarket programmed. i just did a search or the 2000, doesnt come up in 09 service info.

Hypertech has a programmer for the 09 Hemi? I stand corrected.

I did notice that the truck downshifts much sooner with tow/haul turned on. The little bit of engine braking is appreciated when towing.

Yes. I got lucky and got in on the beta test. Right now I am running the regular gas flash and there is little difference between that and stock. With the premium fuel, there is a noticable difference, but it still doesn't address torque management, shift points, or the rev limiter. They did figure out how to raise the speed limiter.

Engine braking is a good thing. I hate it when trucks act like your foot is till on the gas when you let off.

to the "trained" eye/ear/foot--this substantial detuning is very noticable. In my 300C, my SRT8 and my CTS-V, plus recent other vehicles--an after market tune changes the vehicle dramatically.

I have noticed that-at least in my experience- Chrysler vehicles are detuned the most, and seem to be the least user friendly for the tuners to figure out. The SRT engineers have said as much in their on-line forum chats.

So when I drive my Ram, it is easily noticable and very frustrating. The vehicle is substantially de-tuned in a number of ways--most noticeably from a standing start under hard acceleration, and during shifts.

I can't wait for a good tuner (Hypertech, Diablo-whomever) to come out with a fix for this. This truck will ten feel like 390hp/407 TQ. As it is now--it feels significantly less than that.

The info for Hypertech is wrong, It's for the 340 HP HEMI not the 390HP in the 2009 RAM.

I don't know about drag on this truck, but I noticed with mine (when not in Tow/Haul mode) when I let off the gas this thing loves to roll. I guess it's the torque converter not staying engaged. I feel like I use the brakes a lot on this truck to keep from running over cars in front of me.

I have the opposite experience. Compared to my 06 tacoma, this dodge ram feels like its coasting in neutral when I let off the gas. In some of the mountain driving I do where I use to let the tacoma engine brake to slow down I now either have to use brakes/put the Ram in tow/haul mode/ or downshift to 4th to have any meaningful engine breaking.
