Just wondering how the newer 4.7 compares to the HO? Basically the same thing it programmed for flex fuel?

Also I have noticed our 2008 does not seem to actually accelerate that well for the 290hp it's supposed to have. Doesn't jump off the line like the taco I test drove. Is that the torque management doing its thing?

 

unplug your ABS and you should feel that power....

 

ABS?? anyhoo..

The 08+ is a newer more powerful motor than the HO. The HO is a more powerful version of the '07 and prior. 260 vs 230hp. The 4.7 in general has a lot of it's torque at around 3000RPM, you'll notice this when trying a 0-60 time. If you have 3.55 gears, that's why you feel pooie off the line, 3.92, 4.10, and 4.56 will feel better, and a standing stop has more to do with the torque converter than it does the torque management. the 545RFE is just a sluggish feeling tranny really. Shift kits really set them off though, and a stall converter in the 2500-3200 range would help too.

There's a simple $50 upgrade by sonnax that increases the fluid pressure in the 545RFE, solidifies the shifts a bit. Superchips tuners can remove the torque management too.

One thing about the 545RFE is it's a pretty good tranny for the 4.7, same exact transmission that the hemis use. less power at the crank makes for a longer lasting drivetrain.

 

lol frenci, more power at the crank just means more fun, you can have a hell of a setup if u know what your doing, i know what im doing when it come to chevys but dodge im just learning as this is my first chrysler product.

yes ABS crontrols your torque management, and from 06 and above most dodge dakotas have it installed, if you ever get in your truck and turn it on, and you see a slippery little car on ur dash board that lights up red, you have TM. TORQUE MANAGEMENT, and it CAN NOT be turned off by a dealer, only by a aftermarket programmer. sorry but its not in your torque converter mostly, its the abs not letting the other wheel spin, if one dosent both wont, hope that makes some kind of sence...

 

[quote=FrenicX;2704609]ABS?? anyhoo..[quote]

T.M. is controlled by ABS.....

 

now how do we eliminate teh dbw lag

ive already used the cortex for all its worth but it still feels laggy when i mash it while rollin down the highway

 

I think you are getting torque management and traction control confused. Traction control should only come into play if you start spinning a wheel. It's reactive and controlled by the ABS system.

Torque management is proactive and limits engine torque to give softer shifts and prevent driveline damage.

 

when your in drive click the od/off or tow/haul button it will shift into 3rd then when you got WOT depending on your speed it will do a 3rd or 2nd gear pull. i found it works much better than flooring it in drive at 70mph

 

Torque management is in the TCM I thought. But regardless, what you're talking about is traction control or electronic stability control. Torque management is something different and it's sole purpose is to affect how the hard transmission shifts, either to improve the life of the drivetrain or for the comfort of the passengers I'm not sure.

 

all 3 are intergrated, i work at a dealer i work with my techs very closely, abs system monitors the traction control - traction control is the torque management system for a dakota.....
