It is locked almost the entire time in 3rd through 7th gear.
I enjoyed the video. I'm towing a 23' TH with my 2019 Colorado. The V6 handles it fine but downshifts to 5th on any sort of incline at freeway speeds... the 2.7 turbo really seems to handle that nicely. An upgrade might be in my future.
My new favorite channel! I'm a data nerd as well and this just tickled my fancy the whole time! Keep them coming 😊
Thank you, is there anything in particular you would like to see?
@CJIEngineering just more videos like this. I had a 2020 1500 5.3 that I loved and 2022 1500 2.7 and hated it so I traded it in for a 2024 1500 duramax and it's a game changer.
Great video! Thank you.
I have followed you since your first testing of your Silverado. I know you said you wouldn't gain any power/torque when using premium but at the same time as you eluded to, you wouldn't loose any or as much power/torque in those times where its pulling time on 87 either so it could be looked at as a gain. I have tuned my 6.2 Yukon (with the 8 speed) and I have also data logged the difference in timing being pulled when running 87, 91 and 93. The difference between 87 and 91 is pretty big but the difference between 91 and 93 isn't worth the price difference most of the time. I always run the 91 without ethanol. When I ran my 93 test it was with ethanol. That being said when towing I would personally always run 91 and probably 87 when not towing. Spark knock is pretty hard on an engine. Thanks for the video!!
Thank you for following the channel. I haven't put out much content lately but I'm hoping my process is more refined so I can do some videos more often. Also thanks for the extra detail on octane and knock. I'm curious where you get 91 w/o ethanol. Around me we have 89 rec fuel but it's about $1/gal more than 93. That would be a great test but I'm not sure it's available at enough places for me to do some long distance towing...
@@CJIEngineering I live in Iowa. 91 with no ethanol is cheaper than 93 with ethanol. Every once in a while I find I can only get premium with ethanol. It’s rare for me to come across a fuel station that doesn’t have 91 or higher premium. Any premium fuel is better than 87 when towing I have found.
@@jockosboy17 Thanks for the information. Next time I'm driving though Iowa I'll make sure I look for ethanol free fuel. That might be a good test :)
@@CJIEngineering honestly, it's weird we even have it as we produce the corn and ethanol here that goes into gasoline.
@jockosboy17 , I was actually thinking the same thing :)
So towing this with a family of 4 is no dice. I have a 2024 Chevy Colorado Z71 and looking at what type of travel trailer I can realistically tow for family vacations. Payload capacity is the biggest consideration which boils down to hitch weight. For my family I'd like a travel trailer with a hitch weight less than 600 pounds. I've come to the conclusion a 26' travel trailer with double bunks and a slideout is what we will be looking for.
You are correct, with this setup we put everything that we want to carry in the trailer or on the rack on the back of the trailer. We have the capacity to have my wife, myself and our two dogs and we're at the maximum. I have another camper that is the same length but is a super lite model with bunks and a small slide, tongue weight is under 550lbs and it weighs 5,000lb so there are options out there. Thanks for watching and commenting.
Enjoyed the video!
Thank you
I have a ‘23 Canyon Denali that I plan to tow a ‘25 Grand Design Imagine 22MLE. You mentioned that you would not tow through the Rockies with the Colorado. Do you feel the truck doesn’t have adequate power or are you basing that on the lower towing ratings at elevation. Or for that matter, do you think the trailer is just physically too large for any type of mountainous areas? Love the video, very informative.
Really enjoyed the video. Would love to see more on this truck and on the Duramax too. I’m looking to purchase a truck within the next year and I’ve been going back and forth on a new Colorado or finding a used LM2/LZ0.
@zachbritton448
Thank you for watching. I have a few questions for you. How often do you tow? How much weight do you typically tow? How far do you normally drive every week? Those are all important questions when it comes to the LM2/LZ0. I did have a few issues with my LM2, the LZ0 has been rock solid over the first 20k miles.
@@CJIEngineering The main thing I am looking at is the fuel economy. I don’t tow very often and if I do, it’s less than 4K lbs. I do commute quite a bit for work which is mostly highway. And I’ve always been a “diesel enthusiast” if you will.
@@zachbritton448 With what you have told me the 3.0l Diesel would be a great choice, IMO. The only caution that I would have for you buying used is trying to find out if the proper oil was used inside the engine since it was new. These engines need the Dexos D oil, low visibility and low ash. This is important because ash can plug up the DPF filter and run over $2,000 to replace. These are a few issues with the LM2 engine, wire harness issues and excessive oil consumption. Both can be fixed, repair the harness and replace the valve cover and the #2 glow plug. The LZ0 has both of these fixed, 2023+ but they also made changes to the security in between the computers that makes it almost impossible to tune the LZ0. The LM2 does have some aftermarket modifications available. My LM2 had both issues, only one was fixed while I owned it. The LZ0 has been rock solid so far, just crossed the 20k mile mark. Let me know if you have any other questions and good luck.
I’m sick and tired of the CAFE add-on’s for car and light-truck engines, particularly the ACM system. I’ve used a ACM defeater (plugs into diagnostic port) for my 5.3L GMC V8s since I had experienced a total valve train failure in the 2016 GMC Sierra with that motor. I’m driving a 2019 now, with ACM defeater installed constantly. Zero issues, have over 137K miles on it, with about 20% of those miles while towing a 6500 lb boat rig. I’m curious if there are defeaters available to stop the ACM in the L3B engine also, mainly because I’m thinking of downsizing to a GMC Canyon with the L3B (310hp/390fpt).
I agree with you 1000%. The AFM on the L3B is a lot different than on the GM V8s, it slides the cam via a electronically driven pin that engages/disengage, it's also use for engaging the high HP profile. I truly despise the hydraulics lifter method, especially since they seem to be super unreliable. I continue to monitor the market and it doesn't seem like one is available but HP Tuners is super close. I'll make sure I post back when it's available and if I send my ECU to get it unlocked :)
@@CJIEngineeringthank you. I’m thinking CAFE will be thrown out, so all of these add-ons may disappear quickly. I can’t imagine the cost to GM and the consumer as it exists today.
How's the overall feeling of towing with this vs a full size truck? You mentioned feeling like you were being pushed. Is it a significant difference in your confidence level towing with a full size vs mid size truck?
Yay your back! I have the L3B HO in my 2022 Silverado and love it. The thermals you've got are quite good as well (coolant and transmission temps), nice and mostly stable only fluctuating a few degrees here and there. How's your empty MPG been so far? In my Silverado I'm roughly 17-19mpg per tank in the winter, 19-22mpg per tank in the summer with a current lifetime MPG in 20,200mi of 19mpg.
Great to hear about your 2022 Silverado. If I'm nice to it 70mph on the highway I'll get 23-24mpg. My normal commute is 43 miles each way, speed is higher at times and lower at times, try to stay with the traffic I get 21-22mpg. Overall I'm really happy with it. I use fully.com to log all the service and fuel economy numbers. If you search you should be able to find my trucks. I'm going to do empty loops to document it for everyone. Thanks for the question and for watching, I really appreciate it.
Hi there I have a 23 trail boss Colorado so that means I can tow 7000lbs no problem my have 1403 payload thanks
Is the 200 plus temps normal, while not towing? Or are they more like 180/190* thanks
Oil is ~210, Trans is ~195, and Water is ~200. These engines have a very sophisticated warming/cooling system to keep everything in an optimum range.
What sway control set-up are you using?
I use a Hensley Hitch, Aero Model with 1,400lb weight distribution bars. The front of the 27RES is really heavy for the weight and size of the trailer. I have tried friction type sway control and the Hensley is the only way to go in my opinion. Not cheap but it takes care of 99.999% of sway. It makes pulling a bumper pull camper feel like pulling a 5th wheel trailer, my first camper was a 5th wheel. You will still feel a little bit of a push when there are strong cross winds but on a trip in the Dakota's we had 25-30mph cross winds and I was still able to go 65mph down the highway without any concerns for our safety, other bumper pull campers had slowed down to 55mph or even lower. They are heavy so you need to pay attention to the total tongue weight and your trucks payload to make sure you don't overload your equipment. Thanks for the question and let me know if you have anything else you would like to know.
Where did you get those towing mirrors?
You should do another tow on 93. I run 93 when I tow my boat in my trail boss. I can feel the difference when it’s under severe load. In my eyes, there’s no way an engine isn’t going to knock and retard timing when it’s already a 10:1 engine and running a max of 27psi of boost. Not to mention, the air temp here in Florida is always well into the 90’s. I bet you’d see an improvement under load for sure.
Great idea. I was also thinking about doing another loop with some larger hills, farther north in Michigan. Stay tuned and thank you for watching and commenting, it really helps .
does it feel like the colorado is being torn to pieces when you hit a dip in the road or go over an uneven bridge ?
Actually it does not. To be honest the frame on the Colorado seems to be stiffer than the 2500 Ram trucks I have towed this setup with in the last several years. It has almost the same payload as those trucks with the Cummins in them...
@@CJIEngineering Thank you, really enjoyed the video.
Question question. I have the banks idash and my torque rating is all over the map. What is the PID or how can i find the torque rating and transmission gear? Thanks
If you have a modern GM vehicle you can use the "DMAX_LM2" vehicle settings. This one has all the data that I like to record, of course more data on the diesels but it worked great with the L3B. If you need more details let me know and I'll give you some more tips. Thanks for the question and for watching.
Hey is there any way you can send me the spreadsheet you created. It’s legit!
Why did you buy 2 1500 🛻? 🤷🏾♂️ You should’ve bought the 6.2 liter long bed version! 😂
Lol... We'll truth be told I'm a sucker for diesels and I also love me an online 6 so when it came out, 2020, I just had to have one. That one was a short box. Then in 2023 when it got steel pistons, max tow package and a little bump on torque I bought the standard box version. Even with a stronger rear axle and high GVWR it actually has a little less payload :(
I'm not a fan of the displacement on demand that is in the GM V8s so they were never really an option for me.. Thanks for watch and the question.
