Mutli Torque engines

[Crocko From Oz]

Have got a question about the 'multi-torque' engine feature now in ATS.

I'm building a couple of engines with the MT feature, do the engines swap torque parameters 'on-the-road' or do you have to use the 'power mode' feature in settings?

Code: Select all

torque: 2779
secondary_torque: 3050

torque_curve[]: (300, 0.5)
torque_curve[]: (700, 0.65)
torque_curve[]: (800, 0.74)
torque_curve[]: (850, 0.8)
torque_curve[]: (900, 1)
torque_curve[]: (1250,1)
torque_curve[]: (1600,0.93)
torque_curve[]: (1700, 0.8)
torque_curve[]: (1850, 0.54)
torque_curve[]: (2400, 0)

secondary_torque_curve[]: (300, 0.5)
secondary_torque_curve[]: (700, 0.65)
secondary_torque_curve[]: (800, 0.74)
secondary_torque_curve[]: (850, 0.8)
secondary_torque_curve[]: (900, 1)
secondary_torque_curve[]: (1250,1)
secondary_torque_curve[]: (1600,0.93)	
secondary_torque_curve[]: (1700, 0.8)
secondary_torque_curve[]: (1850, 0.54)
secondary_torque_curve[]: (2400, 0)

Any help would be appreciated. Thanks in advance.

The default setting is for the truck to use the secondary torque curve when the gearbox is using a ratio of 1.00 or lower. So if you are using a direct drive gearbox you would only see the benefit in the top gear, if you are using a gearbox with overdrive gear(s) you would also see the benefit in that gear(s).

Normally you would also only get the full torque boost in a certain rpm range, but the way you have yours setup you would see higher torque in the entire rpm range due to your torque ratios. For example at 1700 rpm you would produce 2223Nm and on the secondary you would produce 2440Nm. Typically by this rpm you would see the torque curves be the same again.

Thank you for your time Snoman. Would this be a better setup?

Engine will be a 'tuned' Cummins X15 Euro V (610hp) with ADEPT and will be 'paired' to an Eaton UltraShift Plus 18-speed.

You should check out this mod for making custom torque curves viewtopic.php?f=202&t=218619

I played around for a second and designed this. Basically it's an X15 605hp engine with the multi torque added in.

As Snoman said, the default setting is to use the secondary torque curve when the gearbox ratio 1.00 or lower, you can adjust it using:

Code: Select all

secondary_torque_gear_ratio: 1.0

[Crocko From Oz]

Thanks gents for your time and help, much appreciated. I mainly wanted to know how the game interpreted the code.

[Crocko From Oz]

Just one more question.

As cleber_oro stated above, the sec. torque curve by default is 1.0, which is 7H in an 18-speed, if I change that to 0.86 would that mean it would change over in 8L leaving 8H the only gear in the lower torque curve?

[Snoman]

Almost. The secondary torque curve is used when the gear ratio is equal to or lower than the "secondary_torque_gear_ratio" setting, so in your example the secondary torque curve would trigger in 8L and 8H. All of the lower gears would use the primary torque curve.

[Crocko From Oz]

Ah OK. So I would be better off setting it to default 1.0 (7H) or 6H or 7L.

EDIT: What would happen if I reverse the primary - secondary outputs? ie: make the torque: 3050 and secondary_torque: 2779? Wouldn't that make 8L and 8H the lower torque setting?

What I'm trying to do is have 8H (and maybe 8L) in the lower torque curve when travelling/coasting at highway speeds.

[Max]

yes, it should work as you described.
but most MT engines use higher torque for highest gears, IRL.
