How do I calibrate IAT with MSPNP 90-93
 

Can I calibrate the IAT somewhere in MegaTune, or Tuner Studio, or Do I need to find and use EasyTherm?

If you are using a GM IAT, load the "without AFM" firmware.

If you are using the stock Miata IAT, not recommended for turbo applications, load the "with AFM" firmware.

You only need EasyTherm if for some reason you are using a different, unrelated IAT.

Or if you want to use a different firmware to that offered by yourselves ;)
