More powerful engine and 24 speed transmission for Peterbilt 389

[pieterv77]

I need someone to help me make a more powerful engine for the Peterbilt 389 mod truck. I would prefer the engine to have at least 1500hp and would like the transmission to have 24 gears and 4 reverse gears. I have tried to change the engine myself but have had no luck in doing so. Thanks to everyone who tries to help me.

Engines
Horsepower figures in ETS2 (and ATS for that matter) are display only. Torque is the figure you want to change..
Dbl-click the peterbilt .scs file. When it opens, navigate to:

"def\vehicle\truck\peterbilt.389\engine" directory.
Pick the engine you want to change and double-click it (eg. "catc15_840.sii")
Notepad (better still, Notepad+) will open it.
Change the line that reads:
torque: 2979 (or whatever it says)
Change the number to 6000 (or whatever)
Save the file. You'll be asked to "update archive?". Click Ok (or Yes, or whatever it is)

Transmissions
They're a little more tricky. However, the link below will give you a 24speed transmission with 4 reverse gears for the Pete389. Just make sure it has a higher Mod MAnager priority than the truck itself. There's no manifest or anything included, but ETS2 will make one when you load the game. Transmission icon is generic and the gearbox should show up at the top of the list.

Let me know if it doesn't work.

The transmission works fine and I love playing with it, the only problem I have is the engine. When I change the power of an engine the mod will show up in my mod manager but the truck doesn't show in the Iveco dealer. Thanks for the help.

When you say "the mod will show up in my mod manager".. which mod are you talking about?

Tell me which engine you want to modify and I'll add it to the original ♥♥♥♥♥♥ mod.

I am talking about the peterbilt 389 mod.

The engine i would like to modify is the isxsig_750.

Thanks for the help.

Okay. Added 6000hp (14000Nm) Cummins ISX Signature engine to original transmission mod.
Delete the previous .scs file before you download this one to replace it.

Make sure it has a higher priority than the 389 mod itself.
Specifically made for ETS2, but may also work in ATS as is.

Thanks mate much appreciated.

One more thing. Does that mean i could now change that file to make the motor as powerful as i want?

[room217au]

Yes. Just change the 'torque' value.
I edited the hp and kw values just for show.
Incidentally, that 24sp 'box has 3 'overdrive' gears (22, 23, 24) and there's not much RPM difference between them.
