Computer Controlled Engine Governor In The 08 Avenger?
Has anyone noticed that at around 113 MPH the engine suddenly cuts the RPMs down to 4k preventing further speed?
I have been running speed tests the past few days on a stretch of road that is straight and barely traveled and I have noticed that I really can't go any faster than 115 (Although I ran out of road before I could complete testing for very long after the RPM drop off)
I know damn well the engine has more power than what its displaying at high speedsand its throttling down so that pretty much leads me to believe that there is a governor built into the computer.. Does anyone know anything about this?
I don't really like the concept of my car preventing me from getting a decent speeding ticket...

From what I have read - these are usually set based on what the factory wheels can handle/are rated for.
If you have changed these - you should be able to talk to your dealer about eliminating the governor.

You're kidding me right? That has to be the lamest reason for governing the throttle on an engine that I have ever heard.
If that's true that's unbelievable.. If that's the case, then do you think I should be wary of my wheels shattering at high speeds? Well actuallyI guess not since there really is no high speeds to be had.. lol
I remember reading something in the manual about a high speed regulator or something like that.. They were boasting it as a desirable feature. I'm going to have to break out the manual and read it again..
I'm also curious now where the regulator is and if a chip would remove that limitation or if its just embedded in the car's computer (More likely)
Now what am I supposed to do when I get into a high speed chase? (I have slight road rage tendencies..)

It is not based on the rating of the wheels, but of the tires. You would need to get tires that are rated for higher speeds, cause I am sure the wheels would hold up just fine.

RE: Computer Controlled Engine Governor In The 08 Avenger?
This is not an uncommon occurrence. Most of the vehicles on the road, especially Chrysler, have had these on them for the last few years at least. I know my 96 Z26 Beretta would cut out at 109mph...my 02 Dakota around 117mph...and even my Stratus R/T cut out at about 140ish...
Most cars are governed for a variety of reasons...
1.) Tires on the car are not suitable for high speeds. By preventing the car from going faster then the tires can handle, it keeps the car drivable and safe. That is of course if you consider 100+mph safe...
2.) Some cars are simply not designed to go that fast. Be it by design,lack of handling, not designed for the intended purpose, mechanical stress and failure, etc. A minivan has no real business doing 130mph.....while it would be more understandable for a coupe to be able to do 130mph.
3.) There are lots of groups and local governments looking to crack down on street racing, police chases, and general stupidity in cars all together.
Those are just a few I can think of off the top of my head...and most are probably 85% true...

Most standard cars come withS rated tires....some come withH rated tires.... I typically swap out to nothing short of aW-Y rated tire...
This is the tire speed rating list from TireRack.com, which is a sponsor here on the site...
Beginning in 1991, the speed symbol denoting a fixed maximum speed capability of new tires must be shown only in the speed rating portion of the tire's service description, such as 225/50R16 89S. The most common tire speed rating symbols, maximum speeds and typical applications are shown below:
M
81 mph
130 km/h
N
87 mph
140km/h
Temporary Spare Tires
P
93 mph
150 km/h
Q
99 mph
160 km/h
Studless & Studdable Winter Tires
R
106 mph
170 km/h
H.D. Light Truck Tires
S
112 mph
180 km/h
Family Sedans & Vans
T
118 mph
190 km/h
Family Sedans & Vans
U
124 mph
200 km/h
H
130 mph
210 km/h
Sport Sedans & Coupes
V
149 mph
240 km/h
Sport Sedans, Coupes & Sports Cars
When Z-speed rated tires were first introduced, they were thought to reflect the highest tire speed rating that would ever be required, in excess of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in excess of 149 mph, how far above 149 mph was not identified. That ultimately caused the automotive industry to add W- and Y-speed ratings to identify the tires that meet the needs of new vehicles that have extremely high top-speed capabilities.
W
168 mph
270 km/h
Exotic Sports Cars
Y
186 mph
300 km/h
Exotic Sports Cars
While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed.
225/50ZR16
in excess of 149 mph, 240 km/h
205/45ZR17 88W
168 mph, 270 km/h
285/35ZR19 99Y
186 mph, 300 km/h
Most recently, when the Y-speed rating indicated in a service description is enclosed in parentheses, such as 285/35ZR19 (99Y), the top speed of the tire has been tested in excess of 186 mph, 300 km/h indicated by the service description as shown below:
285/35ZR19 99Y
186 mph, 300 km/h
285/35ZR19 (99Y)
in excess of 186 mph, 300 km/h
As vehicles have increased their top speeds into Autobahn-only ranges, the tire speed ratings have evolved to better identify the tires capability, allowing drivers to match the speed of their tires with the top speed of their vehicle.

RE: Computer Controlled Engine Governor In The 08 Avenger?
Thanks guys for all your info.. I can see the tire rating being a danger..but im friggen depressed now.. Might as well tell everyone to stop modding their exhaust, intake, and engines if all the car can do is 113MPH unless they are just looking for more torque or sound..
By the way I was joking about therim shattering part..but I didntthink of thetires at the timeI said that..
Im sure the chances of the dealer disablingthe governoris slim..
Just another thing to add to the list of things that **** me off about this car.. Has me wondering now how many higher end cars that are beingmarketed for their sporty looks and speed are governed as well.. Like if I buy a Dodge Viper should I expect that to only do 120?
Im not looking to go warp speeds.. but I would like to have a top end speed of around 130.. Just something about the tach dropping down to 4k that pisses me off lol

Bah! I just read my own response and feel like a tard. Wheels = Tires is what I intended.
Yay for working and being slow to think. But glad everyone else set it straight.

Ok, well now that this is established.. Can I make fun of everyone that is putting in cold air intakes, muffler conversions, high flow air filters, and whatever else?
Im gonna start with myself.. I put in a K&N filter for nothing.. and was planning all sorts of engine mods.. what a ****ing loser I am lol (Don't mind me im just being a wise ***) Well I guess I can reach my 113 MPH faster then watch another car pass me...

The mods if you have the money are great for getting there faster. as for the governor it is built into the pcm programming by closing the throttle and injector pulse width. Also this thing is not a very stable vehicle at those speeds any way VERY VERY wishy washy lane changes feel like you are driving on marshmallows
