[6.9]Volvo Drivetrain revision

[MosGuy]

Overall I really like the mod and the true to life engines/transmission selection. The main issue I have noticed is that when using the stock SCS VNL the i-shift will skip gears ie: 1-3-5. But when the mod is enabled and without changing the defaults. It will no longer skip and goes through each gear in rapid succession: 12345. Choosing a mod engine/trans does the same thing. Disabling the mod; the gear skipping functionality returns. Apparently this effect is only on the SCS model. If this bug could be looked into and somehow resolved, that would be great.

Oops missed the post. As rookie_one said the start gear is dependant on game engine and would as such be changed my SCS. And about shifting into next gear, the gearbox simulation is pretty simple, even if driving with "real automatic". My experiences with automatic gearboxes are that they tend to shift up as fast as they can due to economy. But in ETS and ATS gearbox will shift only when you reach a certain RPM target set in the engine def file. So if I set rpm value of 1500, the gearbox will only shift up when it reaches that target.

I think SCS did a good enough job with it, since truck manufacturers have whole departments dedicated to programming gearboxes. But since you have experience, maybe post a suggestion so the devs can adjust it in the future.

Update

6.2: Updated shift points
Switch to stock sounds for SCS VNL EPA2017 Engine

To be fair, a main culprit of that is the fact that north american trucks tend to use lower differential ratios.

Ratios in the 2.6* range on a overdrive transmissions is actually pretty common in North America.

Lower is the ratio, higher is the chance of not skipping.

I heard from drivers at Robert Transport that the lower rated VNL(usually 405 and 425) wouldn't skip gears at all the moment you attached a trailer, even if it was empty

PSA: NEXT VERSION WILL BRING CHANGES THAT WILL MAKE YOU BUY YOUR GEARBOX AGAIN. ACT ACCORDINGLY

For some reason, the fuel economy of my SCS VNL stucks at 5.6 mpg. It is like a fixed value, it doesnt change at all. No matter how I drive or what load I carry, the truck will always be at this number. Realistic fuel consumption is activated, btw. No other truck (with your drivetrain mods) experiences this behaviour. Might be a mod conflict?

Other mods for the VNL I'm using with this drivetrain:

- Oscar reworked dashboard
- Leen sounds
- 6x4 250 gal tank by Ilmiont (it is activated, but havent bought it so far, still using vanilla 6x4 220 gal)

The engine-transmission combo: D13 435V 1650 (the green one), and transmission I-shift ATO2612F (diff 3.40). Maybe this combo makes fuel economy bugged?

Because the fuel economy display in the SCS Volvo is not an instantaneous value, its an average value over time. (Mine shows 4.9MPG)

[LAFAYET47]

@Shirblackspots, I know, but this value is staying for quite too long. I have driven thousands of miles and carried many different type of loads (which should have an effect on the fuel economy) and all this time the dasboard showed me 5.6 mpg. Might drive even more to see if one day this value will change. I also gave high priority to volvo drivetrain in mod manager, just in case.

[Boeing73FLY]

My average is 5.8 MPG currently, which is probably about average (especially in reality) if you're driving through many regions that are full of curves, mountains, stop 'n' go (outside cities). I got a 450hp, 18-speed automated, flatbed trailer loads, sleeper cab...and it has 3,000 miles currently (I started a new profile recently).

@Layfayet47: Why not just reset the dash meters (fuel and trip)? (you need to find the key that does this, if its not set up, do it in the controls)
