IER Oreca LMPC CSP update (Patreon)

I updated the IER Oreca LMPC using an ext_config.ini file.  There was very little I could do to this car due to it having multiple parts linked together.  I did what I could to increase the visuals on it.  I also corrected the location of the flames for the exhaust.  

The file comes with the config extension as well as a data file.  Only the exhaust was changed in the data.  Backup your data file before installing this one.
