This module was designed by MoltenCore Industries for the Toyota MR2 Spyder/MR-S to operate the Toyota AC system without the use of the Toyota OEM ECU for K20 and K24 swaps. Previously, the Toyota OEM ECU was the only computer available to operate the A/C system.
This meant that with any engine swap that had working A/C you also had to have a Toyota ECU either running primary or secondary. With this new module, that is no longer required.
This module will also operate the MR2 Spyder's OEM instrument cluster with ANY engine swap. Your water temperature, oil pressure and battery lights will function just like they did from factory.
