I am searching for an alternative/upgrade to the e99 PCM that I have. I have had no luck finding an exact replacement for the e99. Most people have said that if I am going to replace it, I might as well upgrade. I would like to have a working spare anyway.

I have been told that the DPC422 will work....99.5-2000 or 2001. I have also been told that others, 2002-2003 might/will allow the truck to run but that I will have a malfunctioning tach as well as CEL or SES.

Can anyone verify any or all of this? What is the cut-off year if any?

Thank you for any assistance.

 

There was a lengthy topic on here a while about about something similar.

 

Yes sir, I have looked and what I found did not totally address the new concerns that I heard today. e99's are a bit of a pain with their individual quirks....

I'll keep searching.

 

Look for an NVK or PMT PCM... Done.

 

I think it was 99-2001

 

I'm still wondering what's so hard to "tune" on an early 1999......

 

Thank you. I found a PMT1 and a 3. NVK Seems to address something cold weather related I guess since a chip overrides all of this it does not matter. The above information in red is possibly not correct. Post #14 and #25 clarify the issue and provide links to compatible PCM's for most model years for the 7.3L.

 

"Cold weather related" isn't the case. Anyone referencing this thread should disregard that.

 

I do not know. I have been told several different things by several different tuners. It is to the point that I am confused. I wish someone could shed light on this whole thing because, honestly, I like my truck, but, I do not know if I would buy another e99.

 

Thank you. Based upon the limited information that I have found in the last 5 hours that seems to be the case although, for the upgrade from an e99, I believe it would begin at 99.5 and last through at least part of 2001.

 

Never should be a reason to upgrade unless you can't find a E99 PCM if your dies. Jody's been tuning E99's for many, many years. If anyone tells you must upgrade to tune your truck then they should not be tuning.

Give us a call we'll be glad to help you.

Thank you. The "NVK" and "PMT" codes were the all important key to unlock the mystery. It made the searches so much more productive.

 

Thank you for the reply and the helpful information. I am looking for a PCM for another truck that has given up its magic. I decided to do a bit of research into the matter and try to learn some additional information. I would like to see if the replacement for the dead PCM could also work in my truck and, if so, would it make a noticeable difference. I had heard that some features that are present on e99's were not enabled in the e99 PCM. Those are supposed to be enabled on the 99.5-2000 maybe 2001 PCM. Just a simple experiment...that is the kind of guy I am. I then found out that this was a bit more complicated than I had anticipated thanks to the idiosyncrasy's of the e99. I also realize that the complications are of my own creation......

No tuner, to include Jody, has stated that they cannot tune for the e99. Some have stated that there are limitations, which I completely understand (see Below). I just have a feeling that a few will knock it out of the ballpark with bases loaded while others will cede a walk to first base. So, having stated that, if I could upgrade to a DPC422 "PMT" or "NVK" PCM, thank you again Gaugepro, I could eliminate some "FORD" induced limitations while opening up the possibility of more tunes. I like to have as many choices as possible.... Let's face it....There are not nearly as many e99's out on the road as there are 99.5-2001's. So, I think it is reasonable to assume that there are more tunes available with a greater range of individual tweaks to the base calibrations to address a wider range and or variety of modifications to choose from for non e99's. No tuner that I have spoken with has stated otherwise.

If I am incorrect, please let me know. I will happily edit this and issue the correction(s).

Thank you again for the information.

 

I obtained the information that I based my statement on from a link to a table in a FAQ/post created by Bill Cohron of Power Hungry Performance and a subsequent call to a Ford Dealer where I was told "WTR" stands for weather and he "thought" it was to address an EBPV issue. Also, due to dates/number/letter scheme, they do appear to be early versions/revisions of the base flash. Notice also that all "NVK" PCM's have the "COLD WTR" designation. Below you will find the pertinent information and below that you will find the link to the original post in its entirety so that you may verify the accuracy of the cut and paste.

It is good for PCM's thru 2002.

I did a screen save and placed it in my archive.

I have included this information so that the next person doesn't have to search high and low for hours on end to find it because the information contained therein will assist others with problems beyond the small issue this thread addresses.

It would also be extremely helpful for you to inform the forum as to why the information in the table provided by Bill, the information provided by the technician at the FORD dealership, and then relayed by me is incorrect. If you will do this, no one who has access to this, has to draw an incorrect conclusion ever again.

I would happily provide this information, but I am an untrained novice who relies on experts like you for assistance. Thank you for providing this clarifying information for the good of the forum. Thank you for you other contributions as well.

 

Let me just expand on your desire for more tunes, or the possibility of a greater number being available.

I have 3 loaded on my Hydra, I really use 2. A DD tune and a tow tune...that's it. The un-used tune is some sort of perf tune. Never use it. Cody sent me them, I loaded them....and I drive it. I only switch when I hook on the trailer. Would a high idle be nice? Sure.
