Add set_node_defaults in the meshwheels section. Play with the second value set_node_defaults -1, -1, -1, -1. Also you should add separate snd on front and rear.
Well i did a Ford 6.6L Brazilian NH-TC inline 6 swap on my Pajero out of a parted out Ford CF8000 cargo truck, did the custom ecu remap which has the modifications through it's torque curve and used the gear ratios from a 2017 Toyota tacoma's R156F transmission. Plus the final drive from the Toyota Dyna truck too, I had a 10 secs run time in the dragstrip. haha
