Hey guys, this is my first mod ever and I was wondering if people had some feedback or advice. I found out about AC Car Tuner, started fiddling with some stuff and this is what I came up with. I changed the model to have RPF1s that I got off of the Driftworks S15, added a turbo and changed some other settings, I'm looking for advice mainly on the suspension tuning side of things since I'm not a super experienced driver and I'm finding it difficult to fine tune things.
I left power.lut alone, and added a turbo with ~12 psi.
I increased MAX_TORQUE for braking from 1400 to 2000 and changed FINAL_DRIVE from 4.1 to 3.9 (Swapping to that final drive is pretty common for turbo miatas).
For suspension I decreased ROD_LENGTH from 1.35 in the front to 0.04 and from 0.130 to 0.35 in the rear. I also stiffened the front SPRING_RATE from 19300 to 50000 and the rear from 17900 to 55000.
The miata only had Street 90s and Street tires but for some reason they still had WEAR_CURVE and PERFORMANCE_CURVE files for semislicks. I added a new tire type for semislicks that was a copy of the street tires, but used the semislick curves. I also increased DX_REF from 1.26 to 1.32 and DY_REF from 1.23 to 1.30 (perhaps these are a little too grippy?). I also increased WIDTH from 0.185 to 0.225, however this didn't seem to make a noticeable difference so I'm not sure if it did anything.
Then I used a tool I found online to change the dyno graph UI, and changed the sound files to use the engine noise from a S13, it's not perfect obviously but it works and makes it sounds adequately turboey.
That's pretty much it, like I said just looking for advice on what other stuff I should be fiddling with or any mistakes I made. Thanks.
