I’m pretty sure it’s an Ism because ecm is a CM570. But will make sure tomorrow morning. Cpl on dataplate seems for L10. Maybe PO swapped rocker housing? Are they compatible? Will try to find the esn on block as you said. Hopefully I have some new tomorrow. Appreciate the help.

L20302 Cpl doesn’t match

ISM & M11 basically the same engine. My old freightliner year 2000 had one in it. 330HP ESP.
Very reliable stout engine. Here is the data plate off quickserve, maybe it helps you in some way.

You should be in this area somewhere

It’s your cpl

From what I could tell you have an M11 longblock with CM570 controls. Please understand that this calibration has three different variations for an auto trans and different power curves. I'm assuming you're linehaul with a manual transmission.
Here is what I came up with:

ECM# 3681405

Current calibration:
L20302.37 330HP 1250TQ at 1,800RPM
DO: 02103
SC: 20069
FR: 02584
CPL: 2607

Replacement calibration:
L21133.16 330HP 1250TQ at 1,800RPM
DO: 02103
SC: 20076
FR: 02657
CPL: 2607

You should be able to download that calibration off QSOL. If not, PM me and I'll send it to you.

The B20047 file shows that it is not meant for a ism with a CM570 ecm, but instead, it is for a Celect with an ECMB model ecm.

So there are engines that share Cpl numbers?

yeah.. some engines might have some of the same hardware .. but do have a different ecm and wiring harness.
