E99 xle4 pcm swap ?

Hi everyone I have a e99 f350 cc lb 4x4 lariat. it currently has a xle4 pcm I have read a lot of forums where people say its good to upgrade to a newer pcm. I have been told buy a few tuner companies to look for a dpc-422 family anyone will work since a nvk style can be flashed to a pmt style.

My question is it worth it to put a nvk5 in my truck. I have found one for 100.00 and was thinking about adding it for the near fact that it will allow for the cruise control light to come on. my truck is a 7/98 build date.

Will the pcm swap cause any check engine light issues or any other issues most people say they are plug and play swaps at least that's what ther post say. will it hurt my truck since I don't have aih. will it cause the pcm to over fuel or other issues since it will set soft codes?

I currently have a php hydra and was planning on just downloading the tunes from php website for the pmt1 tunes. seeing how most recommend them. what is everyones opinions and what are the pros vs cons.

Re: E99 xle4 pcm swap ?

I switched mine to a nvk3 for the simple fact that there is more tuning options for the Dpc-422. Plus I didn't like php's shifting for the xle4. The change is as simple as plug and play. It will set a soft code for AIH but it's no big deal. Also I don't get the cruise control light, some trucks have the light and some don't. Mine is one that doesn't.

Re: E99 xle4 pcm swap ?

I switched to a pmt3 no cel light on cruise works.......but a scan at oreilly did find a missing aih code.
my simple ob2 reader never found it.

Idle and tranny shifts improved without the chip.
at 100 I would go for it...all else sell it for more.

You will need to flash back to stock if you use a flash tuner so you can load the new pcm. Or if your chipped you will need a reburn for the new pcm code.

Also while most e99 will work some dont have the cruise bulb..
...I have never seen one that didnt but was mentioned to me before
