Hi guys.

I have Tweak for Z version, its working fine, no problems

Im trying to mod an engine to have 6 cylinders, 158kws and 263nm torque, and everytime i fiddle with Power and torque in Tweak, it constantly changes to different power outputs in game.

Is there some kind of a formula, because I can't for the life of me, work it out.

The numbers you put in tweak do not correspond directly to the car's performance figures in LFS

i.e. Power: 5 in tweak is not equal to 5bhp in LFS.

I think (although I can't remember) for torque, you have to put in a smaller number for more torque.

And enter the number of cylinders first, and tweak the bhp and torque afterwards, because the number of cyclinders drastically affects bhp/torque.

Yeah i did cylinders before.
And This is making me rage, as soon as the numbers change in tweak, it drastically alters the engine in game. I cant workout the formula, its making me rip my hair out.

Just change it with small amounts, standard on most cars is 0,143 so maybe try changing it with small steps 0,1

Ok guys, i did it. As best I can, if anyone wants to get the numbers closer, by all means, but ull probbaly end up commiting suicide

I was trying to get my engine specs as close to a stock R32 skyline gts-t. The information I was using gave me, 6 cylinders 158kws @ 6400rpm, and 263nm @ 3400rpm. Weight 1320kg

I got my specs in-game specs to 163kw @ 6973rpm and 263nm @ a very low 1504rpm.

The numbers I used for tweak to get these figures was Torque: 50 Power: 0.325

I changed my ingame diff ratio to 4.1 to suit the standard R32 turbo, and I was pulling the same 0 - 100km time ingame, to what the R32 did.

Standing testimony that LFS is a precise and accurate racing simulator.

This took me 2hours of hair pulling and raging! lol

I might just add that im in fact a moron and did it on the XRG...

I just fiddled with the XRT then, and to get stock r32 gts-t figures, for power put in .11 and for torque 1.54, surprisingly, The Peak power figures are almost spot on to the car in real life.

The idea of tweaking demo cars is better, because you can tweak maximum RPM's and turbo pressure, which you can't change on S2 cars.

And you can change the wheels too, the max RPM's you can change in the insim tweak or the new Tweak 3?

Torque 50!? OMG , use torque in a range 0-3... not more, because then it is starting to be yy... You know like peak power at 10k rpms and peak torque at 1k rpms.

Hey guys im still here modding my XRG (with turbo now )

Anyway, I've been making specs on tweak to match the following cars

R32 GTS-T
S13 (SR20DET)
FC Rx7 (13bt) (difficult to adjust with engine capacity. Ive got power peak pefect, but not torque, it comes in too low.. its just a matter of displacement, and im working on it further as u read this)

Obviously I'm saving all my specs on wordpad, If it interests anyone, i'll happily share the info.

where i get good tweak???
