Freightliner M2 L9 CM2350

[jaysoto]

Hello everyone I have been following the @m*m^2 guide for the past few days to demandate a L9 cummins in a freightliner. it is perfectly legal in my country. Anyways i followed it to the best of my ability as i have never used this software before although i have tuned pickup trucks with hp tuners so im not completely unexperienced just unexperienced with cummins. So after i got to the end of the @m*m^2 guide i decided to load the tune on the truck and it did not go well. The truck starts fine but as soon as it starts it lopes extremely hard. The best way i can describe it is turning the key off and turning it back on over and over. Zero throttle response. Luckily i loaded the stock tune back on and it is back to normal. So has anyone had this happen before? To me it almost seems like there was a problem loading the tune on the truck but i didnt want to try again. Also if anyone would be willing to review my file and tell me how bad i messed up that would be greatly appreciated. I was going to have someone tune it for me but after reading about all the bad tunes on here I didnt know where to go that wouldnt butcher the tune. Thanks

would recommend getting on mumble, and talking to the man himself about reviewing your work, or any other options he might have...

I tried mumble. I don't really understand it at all

The @m*m^2 is for ISX not ISL, there is a lot of differences between the two engines within the tuning. Rawze has a post with a few guys he recommended. I have used Bengy and had no problems.

Ok I had just assumed since he had a section for cm2350 that it would work for me as well everything seemed to match up with the guide not sure what the difference would be

there are a lot of differences between the programming done on a ISL9 and a ISX... different injection timing, different engine operating mode, different AFR, VGT maps, etc... too many to discuss over forum posts, and easier to discuss over a live conversation on mumble.

go to mumble.info, download mumble. once you install it on your PC, top left click on server then connect, add a new server, enter your username and the IP address is mumble.rawze.com. make sure you set up your inputs/outptus for your mic/speakers, and join the server. pretty straight-forward stuff.

The funny part is that I have not made a guide to de-mandate a 2350 that has all the proper settings for it... that is some hacked up document that someone made based on things did write.. .. and not from me. - I have seen it before. It gets passed around on the truck tuning sites like some kind of dirty underwear every so often due to people not knowing any better.

Its also often bundled inside those complete ripp-off, garbage-can 'delete' file collections that get sold on the auto/truck tuning sites, often for thousands of $$$ to unsuspecting people who are usually desperate and don't know any better. - It is a total scam with nothing but really bad files and engine killing files/templates. etc., hands down. - I am also thinking that is likely WHY there are soooo many people doing this trash-can deleted crap out there, causing harm to every engine they touch.


I would not trust the settings in that document to put in ANY engine.

Getting on mumble is the correct place for that kind of stuffs... so you need to figure out how to get it going.. either on your phone.. or PC. - That is where that kind of thing is discussed, etc. properly.


Here is a link to the mumble software for the PC:

Ok thank you. I think I will just leave the tuning to the professionals. It's not worth it for me to tear up engines trying to do it myself
