I don't understand why the edge and banks systems work by fooling the computer. Why can't they just reprogram the computer like the superchips, etc? It seems like a cheesy way to do it. I would like to have some more horsepower but I don't really want to spend $800+ and it sure is seems easier to just plug in a box under the dash and press a couple of buttons and be done. From the threads I have read the edge and banks give the most power but I don't need the most. Just a nice boost would be good. But my main question is why can't the edge or banks get the same results by reprograming the computer it self?

One advantage to modifying the signal is that you can remove the add-on module and there is no evidence that you modded the engine. This can be very advantageous if you have any warranty claims.


Also, both banks and edge watch EGT's and can backoff the add'l fuel if needed - built in protection. With a programmer you are limited to the stock CPU's safeguards.

I am new to diesel so don't blast me for my dumbness.


What is the EGT's that I read about on here?

I here what you are saying. Which method is better and what is the difference?


A programmer takes out or removes some of the factory programing. It then puts in it's own idea of what should be happening.


Why does a module not due the exact same thing? Seems like it should be able to. But it really can not. Because it can only modify values that were there in the first place.


As far as which method is better? I have asked this question here and at other diesel websites. The people in the know never speak up. I think it has something to do with the fact that most companys sell or manufature both types of products and do not want to hurt there bottom line or step on any toes.


The little testing experience I have tells me that a downloader will actually give you more off idle response and less turbo lag when compared to a module? Other than that I am not really sure of other advantages or disadvantages?


Flame on!

As Fred has said, the fact that there are no programming changes to the ECM is something to be seriously considered in the event of warranty claims. While there are laws saying the factory has to prove the mods caused what ever problem you might have, they can deny warranty and you have to get a lawyer...http://www.dieselplace.com/forum/smileys/Confused.gif


Another advantage to the modules you mention, is power changes at the touch of a button for the Edge, or rotation of a knob IIRC for the Banks if the Attitude is used on the Edge or the speed loader on the Banks.


The Edge also comes with the ability to monitor a bunch of functions, max EGT, max Boost, trans slippage, RPM's, engine temps, etc. so you don't really need to buy those gauges. The Edge can also be set to cut the fuel if pre-set limits for EGT or boost are getting too high, as well as cutting fuel if transmission slippage is detected. IIRC, the Banks also monitors trans slippage and EGT's.


While they won't change your speedo for different tire sizes or raise RPM and speed limits, not all programmers will do that either. The Edge can be programmed for different tire sizes, but will only display that corrected output on the Attitude monitor.


So there are a few things to consider about modules versus programmers.

Exhaust Gas Temperature.


Usually measured right out of the engine and before the turbo although some choose to measure it after the turbo, and some here do both. The reason being power mods can produce high temperatures capable of damaging engine or turbocharger components...http://www.dieselplace.com/forum/smileys/Confused.gif

That works for right now, but the factories are looking to tighten up warranty claims and I don't think determining if the ECM programming has been changed is too far away.


Think about your home computer, everytime you write a new file, it dates it. Even if you erase that file, or change it, some remnants of the file remain unless you do some very specific things with the hard drive. I'm no computer expert, but it would seem to me that changing the programming or hardware on the trucks computers, so a change to the EEPROM's might be detected can't be too far away.

This needs to be moved to the power and performance forum

And there is another issue. What if the programmer won't put your stock information back in when you try to return to stock, or it screws up your stock info. Wont happen you say? It happened to me.

I had that happen to a friends '03 and i was passing kittens!


but on the 4th try everything worked fine.

Whos downloader was it?


What did you do to solve your problem?

Quad. Had an acquaintance at a dealership reload the stock tune for me.

I agree that in the future they will be able to tell, but they will be able to tell on chips also.
