Best TSB ever.

they do that with electronics. We buy HP printers, we always get the lower spec'ed one, the one that is slower, or with less memory, etc. then we reflash the PROM with the code from the higher spec'ed unit (by changing the name of it to the code of the lower spec'ed unit), it then performs like the one that is more expensive.

Basically on the 6.4's, or was it 6.7's, the injector(s) would crack leaking fuel, IIRC, so when it went into regen and even more fuel got added, it would eventually load up the exhaust with fuel and then it was a nice flamethrower of about 1200^F. I think Ford did a reflash and replaced a couple of the injectors as the fix. And the reflash was nothing more then shutting the engine down for 20 minutes after the incident happens. Didn't matter if you were in the middle lane of the 405 in rush hour pulling a 45' gooseneck, once it quit, you weren't going anywhere for a good long time.

Everyone does it.

Especially class 8 with engine programming/power.

There is a certain manufacturer of T-case for the boom trucks (for sake of anonymity) for the crazy heavy duty 4x4 systems.

well they only make 2 models and they are rated for different tonnages/use and etc. One costs a lot more and that is the only difference, they are mechanically the same. They basically escrow'd the warranty costs into the other unit because they know that the application is going be more severe causing more wear and having a higher warranty rate than the lighter duty application.

Processor manufacturers have done that forever. The difference between the low-speed version of a chip and the high-speed version is that when they were tested the low-speed version was found to have more errors in it. That's really the basis of overclocking; you buy the lower rated chip, then tell the BIOS to run it as if it were the faster one and try your luck on stability.

In reply to ReverendDexter:

That's how we got the AMD tri-cores.

I remember back in high school or shortly after (early to mid '90s), a friend of mine bought a new computer. Not being able to afford the fastest one in the line he was looking at, he got the second fastest one and figured he'd upgrade it when he had more money. After he got it he started to research what he needed to do to upgrade and found out it was just a dip switch setting.

I loved the days of setting the clock and multiplier via DIP switches. It's a shame I grew up on the tail end of that era.

More Jeep retardedness....

The YJ came standard with a 15 gallon tank, with a 20 gallon being optional.

They are the same tank.

The filler neck on the 15 gallon is longer and sticks further into the tank so that it shuts the pump off at 15 gallons. To make it a 20 gallon tank, pull out the filler neck, cut off about 6", and reinstall it.

I've heard this is the difference between a 6 year water heater and a 12 year. Same unit, but the 12 year costs more for the expected higher warranty costs.

Same with most of the over-the-road diesel engines. Want the high output? Flash it to the higher output and kiss your warranty goodbye. The Cummins 5.9 used in the Dodge Ram and everything else was a great example of this sort of thinking.

That makes perfect sense, really. The extra cost of the 12 year is basically an insurance policy.

There is a similar deal on the TJs as well. The tanks are the same.

My 2002 Libery had the 45RFE. While it was theoretically a 5 spd. In daily operation it was a 4 spd. Two second gears . 1.67 ratio, 1.50 ratio for 2nd Prime. In 73k miles , I couldn't see where it made a huge difference.
