CM 2350 injector question

Cummins does not make a program for the CM2250 ECU that is compatible with CM2350 hardware. - I have had to make custom programs for that setup for people several times in the past. Because they are so stupid, the ignorant stealershits will sometimes put a CM2350 engine/block as a replacement engine into a truck that takes a CM2250, then slap on the CM2250 ECU so the older emissions systems will somewhat work. Problem is that the internals are NOT 100% compatible/very different!...

* They have very different compression ratios.
* They have very different injector spray pattern designs.
* They have different cams, piston, and other components in them.

The engine will run, but it leads to...

* slight power losses.
* fuel mileage and other efficiency issues.
* fuel impingement problems.
* Shortened engine life.
* Increased sensitivity of Emissions system troubles.


-- The red engine maker does not have a correct program for this situation. The only proper solution for such a bastard child is custom programming. Everything from injection timing, compression ratio offsets, injection pressures, intake and exhaust volume efficiency settings, and other internal differences need to be corrected so the ecu can run the 2350 hardware correctly again. these changes also need to to be applied for the correct program that is compatible with the make/model truck too. - I have had to straighten out a few already for people because the a-hole stealershits that are doing this crap aren't solving this issue.

-- I see a trip to GA (likely my house) in your very near future to have the programming fixed in that thing if your running a CM2350 engine on a CM2250 ECU. - Especially if you say that they did not even bother to set the right injector trim codes,.. your problems are worse than you think.
