SCMT-Possible Codes even when returned to Stock
Mike, I bought a chip from you a couple of years ago and when I got my new PSD, I decided to research new chips. I have arrived at the SCMT as the best possible purchase.
However.....
Dealers are VERY leery of chipped diesels. I thought the SCMT would leave no evidence, but according to this post on ford-diesel.com, it does.
clicky, clicky
Have you verified this with an autotap or somesuch? If so, would an autotap be able to clear all codes?

Don't be too sure about not throwing a code. We have found the SCMT to throw either a P0603 or a P0605 memory code due to the removal of the stock programing. This is a tech's first clue to a chip or programmer.

Hi Nightfall,
That is not what we have seen at all. The only time we've seen the P0605 error code is when it's *supposed* to be there, which is if the internal eprom chip is turned off, such as when a Superchip module (not a Micro Tuner) is installed on the J3 connector, or if the internal eprom chip actually *fails*.
The P0605 code is *supposed* to be present anytime the Superchip module is attached to the J3 connector, and immediately disappears as soon as the Superchip is removed, that's how that circuit works, it's an external override data path. By the way, all the P0605 code does is identify whether or not the internal eprom chip is **currently functioning**, nothing more! it's a *temporary* code unless your ECU's eprom has an outright failure, which does happen from time to time in stock trim like any component will occasionally, but not often.
The Micro Tuner does not cause that code, as it does not turn off the internal eprom chip, it communicates direclty with that eeprom chip to change it's program, very simple. We have *never* seen either code you mention either with this tuning or after the Micro Tuner's programming has been removed. The P0603 is just a code indicating an error in KAM (keep alive memory), and once again, this is something we have never seen with the Micro Tuner on any PSD.
In fact, most of the error codes that can be seen if the ECU is reprogrammed or if a chip is used and teh ECU is scanned before the ECU has been cleared or the vehicle has been driven 50 miles are generally false or strictly temporary codes that should be present anyway under those conditions, and are eliminated either after clearing the ECU properly and fully after the program change, or by driving the vehicle for about 50 miles.
The bottom line in all of this is that you need to remember what your rights are under the law with regard to the use of aftermarket parts of any kind and any potential affect on your warranty, as it does *not* matter what anyone says, it's the *law* that porvides you your rights as the vehicle owner.................................. you have the absolute right to do *anything* you want to your vehicle, and as long as what you do to it does not *damage* the vehicle requiring a repair, then your warranty remains fully intact, by law.
Autotap can of course clear codes, sure, we use Autotap sometimes ourselves, and we are a dealer for Autotap.
Dealers have unfortunately seen some bad results of poorly tuned chips in Powerstroke diesels, as everybody and their brother has claimed to be a PSD tuner over the past few years, and some aren't qualified to do this and have caused problems, to be sure. We've seen engine damage result from the use of some PSD chips due to EGT's (exhaust gas temperatures) that are far too high, which is the result of either very poor tuning (usually) or in some cases, the result of the vehicle owner using a program that is too "hot" for the manner in which the vehicle is being used, such as using an Extreme program for heavy towing, for example, and we don't evne offer that kind fof program to anyone but bonafide racers who are required to sign a release for us to make a program that hot.
Some chipmakers think it's a race to see how much power can be made in these PSD's, and throw safety and correct tuning right out the window in their attempt to rack up the biggest dyno numbers. Unfortunately, many people respond to the biggest dyno number claim and think that is all that there is to be considered with the use of any chip or powertrain programming product for the PSD, and forget about any consideration of suitability for purpose, EGT's, etc.
This is perhaps the single biggest advantage of the Superchips tuning for the Powerstroke diesel, as a result of having tuned these vehicles longer than anyone else and producing the world's first aftermarket powertrain programs for the PSD, we produce more power with even *lower* EGT's than from the factory on our +60 HP program in most cases. Even on our higher output programs, the change in EGT is far less than any of our competitors.
The point being, dealers have seen problems with chips for PSD's, and so they are in some cases quite naturally a bit leery. All the more reason to use only the best powertrain programs on the market, which is of course the Superchips tuning. It's the safest, and produces the lowest EGT's and is *still* 50-state emissions certified for the PSD.
Sorry to go on at length, just trying to provide you with as much info as possible. If you'd like to go over this in detail, please give us a call at our number listed below, and we'll be happy to!

Thanks for the info. You should (or might have already) post this reply over there. It might help a few folks decide. If I decide to get a chip, I already know I want the SCMT due to my previous experiences with the SC in my '98 150. That was never the issue. I just wanted clarification on the code issue, as I've already studied the MM Act so I know where you're coming from there.
Thanks again!
Thanks again!
