ECM programming for a 2000 N14

You would need insite and calterm. Unless you know what your doing it's easy to brick the ecm.

 

If you have a 370/435 setting currently then the base variant of the engine is a 460E. It should say for certain on the engine tag. It will go to 460 with no issues with just an ecm flash. I ran a 99' 460E with the ECM from a 525E (redtop), 525/1750 setting, for several years. (the original ecm took a crap) Ran strong but the stock turbo would run outta breath up top. Smoke a bit on accel after idling for anything longer than an hour. MPG's stayed about the same as pre swap.. 6.5to 7 week to week.

 

I have the 2592 cpl # horrible mpg 5.5 at best it's set at 500 might turn it down to a 460?

 

You might get it from cummins,eBay would be cheaper.

 

Need to make sure everything's in good working order. No boost leaks,exhaust leaks,valves set right.
I had the same cpl pulling a van,running the east coast. Last ifta was 7.53

 

Calterm if you search eBay it comes as a package,insite,calterm,inline adapter.
N14 ecms are finicky,especially the older they are. I'd let someone who has experience tuning ecm's do it,unless you have a spare ecm laying around
