CPL 4583
Original EF10113
Current EF10294 (changed at some point by Ryder)
Other than the HP changing for 415 to 475, what else is different.

program EF10113 vs. EF10294 ...

== Program EF10294 allows for more drift in speed during cruise control operations.

== Intelligent coast manager feature is on in the EF10294 and off in the other one.

== Load based speed control clamps at 1500 rpm on the EF10294 and at 1650 rpm on the EF10113. - Everyone hates load based speed control because it makes the truck feel weak/gutless when lightly loaded.. because it holds back power, simulating that your heavy all the time. BTW: it is turned ON in both programs.

== The Smart-torque 1 feature is turned ON in the EF10294 and OFF in the EF10113 program. Many people do not like this feature of the engine, as it drops torque after about 30 seconds of hard engine acceleration or when climbing a hill.

== The Smart-torque 2 feature is turned OFF on the EF10294 and ON in the EF10113 program. Many people do not like this feature. ST2 is applied by the estimated weight of vehicle and its load (determined by how hard it is to climb hill, how hard its driven, etc.). It effects load based speed control (that thing everyone hates where their truck feels like it pulls good when heavy, but feels like it can't get out of its own way when light), driver reward system, and fuel economy control system.

== The 'Inpower' option select is set for 'Smart torque 2' - assisted power/fuel reduction on the EF10294, and it is disabled in the EF10113 program.

I.E.> The EF10294 uses Smart Torque 2, and the EF10113 uses Smart Torque 1.

== As far as power goes.. the EF10294 is actually set to 485HP@1600rpm. The EF10113 program is set to 425HP@1700RPM. Both programs are set about 10hp above their advertised settings.

Other than that, pretty much everything else is the same.

Thank you. Load based speed control was previously disabled it looks like.

For CPL3937 engines. ...

Code:

EF10044 = 450HP/1750trq@1800 RPM. Smart torque reduces torque to 1550 after a short bit.

EF10074 = 475HP/1650trq@1800RPM. It has NO smart torque and has higher torque from 1500RPM and above compared to EF10044 due to the HP increase but slightly less torque (1650 peak) below that.

I have CPL 3937 400ST not demanded my program is EF10049. I run that I-40 from Arizona to Oklahoma and back. Is there a program that will allow me to pull hills a little better but not kill my fuel mileage?

Program EF10074 is 100% compatible with program EF10049.

So I realize I have insite 8.5 And I can't seem to find the calibration files for this one. Cummins website only has
the calibration files for 8.8 and higher. Does anyone know where I can get what is needed for my for my version of insite? (PM please).

[Matrix2613]

Hello, I found this site after some Google searching and I am impressed by the plethora of information available.

I am looking for an ecm calibration code, currently have a 400 hp/1650 tq engine and would want to compare a 450/1750 file or a 475/1750 or so. I believe that this Truck can handle up to a 500 file without hard part changes, but I don't want to get to the point where we are sacrificing fuel economy/reliability for power. Truck is an old JB hunt truck with 370k miles on a CM2350A ecm. (x15 efficiency)

All the emissions are intact, just want a little more grunt to maintain speeds.

My guys don't go faster than 65-70 but loosing speeds on even small hills is a bummer, especially since I frequently do OSOW.
Info from Cummins parts-
Marketing Model Name X15 400SA
Service Model Name X15 CM2350 X114B
CPL # 4342
ECM Code HD10313

But will confirm the file currently on the Truck this week when it comes back from otr
Thanks!!

Having worked for JBHunt I know they like to play with some of the settings in the ECM "for efficiency". Driver rewards, cruise droop (i think that was the name), etc..

Also, last I knew was back in 2015 they were spec'ing their trucks with 2.90ish rears and 10 speed manual's. Back then all the trucks were governed at 62 but they were letting the driver rewards boost you up to 64 if you got higher fuel mileage. That kind of combination will never zoom up a hill. I didn't care for the freightliners they tried back then, although those Prostar+'s were pretty nice to drive. Not sure what specs you have on your trucks, but JBHunt liked their fleet to be mostly uniform and interchangeable so they could move equipment between accounts.

I do have to check on the rear ends, but this one is set up with an automatic. Drives like a car and my brother in law seems to like it better then the cascadia he was driving before.
