Bob my 1999 U320 40' CPL # 2371, M11, 450 E Plus,  Build #5391

Hope this helps you.

Bob, just curious, what are you working on?

Bob, Cummins can hook up and read your configuration, and can upgrade it to the 450 Hp @ 1450 ft lb if it is not already at that setting. If they know you, you might be able to have them install a little higher setting into the ECM, if they do not know or trust you, they will most likely not set above the 450 @ 1450 ft lb.  All the settings are on their computer, they just pick what they want and send it to your ECM.
Just my opinion working with my local Cummins guys.  We have always worked well together, might be why my creation is a bit more on the upper side than the 500 @ 1550 ft lb.  They talked about 580 hp at one point, unsure if that is where it is and do not care, it is fun to drive.  You do not need a speedometer to tell if your gaining speed.

That is exactly why it took their book worm over 2 days checking to see if my CPL would support any upgrades, they)determined all I needed was the rare (there are 3, just one that is the special one) waste gate turbo, the sender on the intake that controls the waste gate on the turbo, and they located the wiring harness where the sensor plugs into. Then the new ECM program was all mine needed.  the base engine is the same as the later 500, just no EGR, but same head, injectors, pistons, rods etc.  I had earlier installed the girdle that the 500 units have standard.  They indicated only the units after late 99 run had these features like mine and could be up graded, The early units like yours, they would not touch them.
One funny, all the shops in Nac, know my coach has a very different engine.

Bob,
I just had my ECM updated earlier this week.  I'm looking at the Insight printout for my M11 Celect Plus.  The CPL is 2371.  HP listed is 450, torque is 1450 at 1200 rpm.

Bob,

This may not be at all helpful — in fact, I may understand so little about the topic of this post that I'm answering the wrong question.  But you asked about CPL numbers for 97-99 M11s.

Our coach is a 1999 U320, Build #5567.  But I think (?) ours is an ISM.  The last printout I have from Cummins Atlantic, when they read all the act and inactive fault codes, shows the CPL # as being 260800, but the engine model as an ISM-RV450.  Sounds like the engine you DON'T want to know about?

I also have CPL2371 manufactured 5/98. I am interested to see what you find out.

Thanks,

Bob and others.

I just found the time to check the CPL on my 1999 and its 2371. The engine ref on quickserve is M11-450E+

Performance wise I have timed 0-60 several times (usually leaving a rest stop thats flat) and our coach is right around 23s give or take depending on where the tanks are at. We go down the road at 29K give or take...

It would be interesting to start a collection of 0-60 times (along with weights) as it would give everybody an easy way to check if their coach is performing as expected.

Cheers

Chris

Excellent idea.  Do you tow?  Mpg?

Length of coach?  My 1999 U320 weight is almost double yours!

Hi Brett,    29K lbs for a 1999 36' U320 no slide and a light load sounds about right. Our 2001 36' U320 single slide normal load is about 31K lbs. 

Brett, just a side note on your coach. I noticed that you have quite a few screws loose(the coach) along the trim strips etc.
