I was at a dealer today and was told that a dodge engineer explain that in the computer control box at 5,000 miles a resistor is burned out to disconnect the break-in program that is design to keep the HP and torque down. Once the 5k miles is reached the computer is set to run at full 325 hp and 600tq.

The engineer also said many new vehicles from other companies are the same and have a break-in circuit.

Anybody out there that can verify this?????????

thanks Michigan Steve

That sounds like hogwash to me. Even if there was a break-in program, there's no reason they'd have to "burn out a resistor" to accomplish that.

I HIGHLY doubt it. I just broke 5000 miles and haven't noticed any change.

Besides, remember what Ford went through with their Cobras (99 model year I think) that were NOT living up to their advertised HP? Lawsuits, and recalls, etc, etc.

Say someone pulled an engine at 1000 miles an put it a an engine dyno, and it wasn't making rated power. See my point?

MI Steve, Folklore and BS. Wanna see the dealer idiot run? Wave a little plastic bottle in front of him at work.

I do know that Chevy's have a program that limits HP in some of the auto tranny gears (for warranty protection), but its by design - not by burning resistors.

I am not an engineer, however I work with electronics all the time and many consumable items will reset a timer and then the resistor burns out, and the clock starts all over again. My point is the technology makes sense and it is already used on many electronics.

I have no idea if this 5,000 mile break in is true, just reading post of fuel milage picking up after break-in of serveral thousand miles. The idea of switching programming in the computer after a period of time makes sense to me.

Some new vehicles monitor driver habits and adjust themselves to these habits. I think the auto companies would and use this technology.

I read in our local newspaper where some cars already have a record keeping system much like the black box on an airplane to keep statistics for engineers, and how the vehicle is driven, enen the point of denying warranty issues.

My sled did the same thing after 500 KM a diode or redsistor will burn out after the break in period.

I recently breached the 5000 mile mark and noticed nothing different... if this resistor theory is true, I want to know where my additional 6mpg is since I haven't found it yet. Personally, I have to say I don't belive it... sounds like a load of bull to me... JMO

If I'm wrong and it is true... it must not affect performance or economy... at least not on my diesel swilling pig.

So,It looks like I'm off to the shop for the big boy jackstands so I can let this thing run in drive for a few nights while sleeping. Lets see,60 mph x 8 hours sleep = about 8.3 nights.

Changing the program in some way after a break in period sounds like a very good idea to me, but I don't believe it's being done. If it were being done, it would make more sense to do it with programming than by burning out a resistor.
