Power & Torque Issues
This is for the Dev's.

I finally got a lite load to test what I have been suspecting for some time.

http://steamcommunity.com/sharedfiles/filedetails/?id=635326293

I had a load of plows, 6,500 pounds. With the Pete with the engine you get at level 12 and a 13 speed transmission. On near flat road and I still couldn't get up to speed to drive in the top gear. Totally gut-less. I'v had real world trucks that had 370 horsepower 11 liter DDEC2 Detroit engine that could out run what you got in the game.

6,500 pound load, which in the real world of the Commercial Truck Industry would be seen as 2 things, LTL = Less than Truck Load, and super lite load. Using this load I was able to test something that I have suspected. You got the horsepower and the torque ranges dead wrong. Trucks that are designed to haul 48,000 to 53,000 pounds with ease, can't pull a 6,500 pound load without acting like it's got 50,000 pounds on the deck.

This is wrong.

With a load that light, infact any load under 30,000 pounds for a truck with anything larger than a 435 horsepower, should be nothing. Any load under 15,000 pounds should be like running empty.

PLEASE, correct this.

Here is the dash screen grab showing the info.

Agreed. I use the Ohaha Volvo (ported by Galimim) and I'm zooming past the other truck traffic with just the 650hp engine installed. The Kenworth and Peterbilts are gutless.

Are you using automatic or manual transmission? If it is automatic and you are not using a pressure sensitive input for acceleration, you need to turn off "adaptive automatic transmission." If your input is pressure sensitive, then you can turn that option off, or stop flooring the pedal. If it is manual, then you are not shifting optimally.

This is based on the screenshot of your dashboard.

i can agree. even the 550hp version feels underpowered
Steel Panther Feb 29, 2016 @ 12:41pm 
They are indeed underpowered.

I have to agree too, This game looses it's real fill the moment you get in the cab, all trucks are tied to this issue in the game the load does not matter they all act just the same
. I too am driving the upgreaded engine and 13 speed it the trans misson that makes the differance the truck has a higher top end but it still a gutless wonder when is has a light load, it should haul nearly as a bobtail rig on wait they have the same issue all truck drive like they are loaded out at all times. W900 what a waste it was only good for the nechanics because it has a unified hood! a real classsic would be a 1962 pete or something along those lines.

No. I am not using the automatic. I'm from the old school. If it doesn't have a clutch and a shifter, it ain't worth me being in. I'm doing all this with keyboard. I can't afford to get one of the wheels made for ETS2 or ATS. I just am saying that the trucks are gut-less.

The torque curve is missing. Most trucks run with around 1,250 to 1,400 foot pounds of torque. Some higher. That much torque in a truck that is pulling a flatbed trailer with 6,500 pounds of nothing on the deck, well it simply would fly. You could skip-shift from a dead stop all the way to the big hole. And at that weight, with that torque, you could control speed from 55 to 75mph, without ever leaving the big hole without a single problem. Just control your engine idle.

That's great and I don't doubt what you're saying, but for the purposes of this game, you are not shifting optimally. Your RPM is too high. For best performance in this game, you need to keep your RPM between 1000 and 1500 most of the time. Try shifting earlier and see if it feels better.

1000 to 1500? What the.............? IN real life you don't shift that low, 550 to 620 rpm is idle, 950 to 1000 is high idle. You can't drive a truck weighing 80,000 pounds with those shift points, and in the game, trying those shift points doesn't work well either.

I don't know where you learned to drive a semi/tractor truck, but what your saying doesn't jive. Not for a manual transmission. I'm sorry.

I have 18 yrs real world experience. Even Schneider National Carriers doesn't drive their trucks that way. You couldn't pull a mole hill grade doing that.

I dont give a turkey what some freight nut behind a desk thats never drove or rebuilt a engine says , or sees what the constant lugging does to a engine . Back in 93 when i started ya ran the damn things up to 2100 rpm , and Down shifted at 1500 or so depending on the engine .. Fast forward to 2016 where i work Every single engine in our 10 trucks are governed to 2100 . All but One and that is my N14 that will run out at 2300.. And For the 2 stroke screamin jimmies if they was not screaming they was not pulling ,, Ya tripped over the oil jugs from adding oil in the morning , skin your knee on the steps and shut your hand in the door and tried to blow that 2 stroke joke up all day . ANNNNNNNNNND as for the trucks in the game i nail em to the govenor and have no problems on pulling power .

You're trying to apply your real world experience to a video game. It doesn't work that way. I know it has the word "simulator" in the title, but that doesn't mean the game is true to life. Yes, in the real world, 1000 to 1500 is low. In this game, that's where you stay for best performance. I know it's wrong but that's how the game has been programmed. Don't shoot the messenger just because you don't like the message.

Then it doesn't qualify as a simulator.

Don't tell me. Tell the developers.

I had a 1978 Pete 359 that had a 671-N Detroit SIlver Star, with a supercharger and instead of an alternator, it had a generator. Glow plugs that you had to preheat before even thinking about turning the engine over. With a nice 13 speed Road Ranger. And you always had it up against the engine governor, or it simply wouldn't run. Not with 45k behind you. 2100 rpm's, roughly.

I am not some keyboard trucker wannabe. I have 18 yrs real world. Mostly skateboards, covered wagons, stretch decks, even rgn's. But I did my time with reefer and box. Except for the time down under, I never pulled doubles or triples in America. I learned to drive pulling double deck piggy's and hay wagons.

I retired long ago, and I like actual truck simulators as a means to keep my skills sharp. My feedback to the Dev's is to help them make improvements to make this as close to real as you can get.

Otherwise I'm sorry you don't like my post or what I say.

SCS nerfed the engine power because they shrank the map scale. It's not hard to figure that out. They hoped the player would not notice the small scale. If by slowing the trucks down, it would take longer to get to the destination. Less noticable but it didn't really work out for them unfortunately.
