I just installed a brand new PCM from flagship one that they programmed to the VIN of my 99 Dodge Cummins auto trans pickup. At the same time I installed a used 99 Cummins ECM that I got from a friend, but he couldn't remember if that pickup was a manual or auto trans pickup. 

 

There are no codes nor CEL coming up, but at idle when I put it into gear now, it sounds like the motor has a lopey cam in it. If I put it into park or neutral, it idles smooth, and it runs smooth down the road.

 

Now my pickup will display the WTS as soon as the key is turned on, and I don't have to wait for the WTS light to come on each and every time to get the engine to fire up after it's already been warmed up.

 

Are the manual and auto trans ECM's programmed differently due to the factory idle speed or fuel mapping? 

 

We reset the timbo apps to see if that would help, but it didn't change anything.

 

Do the ECM's contain the VIN of the pickup like the PCM, or does it care about the VIN?

 

Thanks for any help anyone can provide.

Auto don't have the anti-stall feature. Manual do have this feature. Fueling map wise basically the same. Idle speed is a idle validate switch that trigger the ECM to seeing that idle is set and uses a totally separate software for controlling idle. Once the throttle moves and shows throttling now the idle software is dumped and the ECM now follows the APPS values for fueling commands.

From what I was told ECM and PCM are all programmed to a specific Vin. And programs can change month to month of manufacturing date. But I was also told it shouldn't hurt anything running it for diagnostic purposes. To make it run right, they needs to be programmed to the VIN.

I have a few ECMs I gathered up over the years. My original had a sketchy wait to start light.

I swapped an ECM from a 5 speed to my auto and it had the same lopey big cam idle. 

It sounded cool to the youngfellas and did work really nice.

I have since swapped it for an auto ECM and it works normal again.

I'm really curious about the flagship one's longevity as their reputation is less then stellar.

I printed out their warranty which says it's a lifetime warranty, so hopefully it holds up to their claim.

 

Snowshoveler,

 

Do you have any other good 99 Cummins auto ECM's?

If they do/do not let me know so I can update the article.

Sorry at this time I just have the 5 speed ECM and that is my spare. Hope I don't have to use it. 

I keep an eye on the stray AC voltage now thanks to info posted here.

I will let everyone know if something does happen to it.

 

I've already bought a rectifier from this site, and now my AC voltage is at the recommended level now.

Flagship buys PCMs/ECMs from salvage yards. They clean up the case and bead blast it to make it look like a reman or new one. Not sure if they program the PCM/ECM or outsource that. We sell about 10 modules a month to Flagship.

How much do you guys sell a 99 Dodge Cummins auto ECM for?

This is really interesting to note..

Hey @99_Cummins_4x4 sorry for the late reply. Unfortunately none in stock right now.

I found a 2 month old Smarty S03 for $300 and I bought a Fed auto 99 Cummins software image from Mads for $120. Now I can flash my 5 speed ECM with the stock auto tune, recalibrate my speedo for my 315/75R16 tires, and enable the high idle feature in the ECM.

That's a good deal.

 

Any chance you would want to ship the Smarty to me so I could enable high idle? 

That's a possibility.

Sweet. Well let me know if that's something you would be willing to do.

I need to enable my high idle and change my tire size too

The downfall of this is that I will have to return my ECM to stock, which will erase my ABS adjustment for my 35" tires and force my speedo to be off by 10 mph at 60 mph again.

 

I was able to download the Smarty Fed auto image to my 5 speed ECM and now it works normal like an auto trans ECM. No more lopey cam idling issue when first moved to Reverse or Drive from Park.

Unfortunately the ABS adjustment for taller tires, only happens when the Smarty is married to the ECM. Once you unmarry it from the ECM to return to stock, the ABS adjustment is erased as well. That was per Bill @ Smarty.

On a side note, and the pickup did this same thing with the old PCM and ECM installed, but after installing the new VIN matched PCM and then the ECM I got from my buddy, my overhead display all works - except for the trip meter.
