Download PL2303 Driver for Windows:
*This driver compatible with our USB-RS232 TTL cable only.
*Dont forget to remove checksum for P30 ecu and add QD2 Crome datalogging script into your bin file. Either it wont work. Checkout for youtube video for more explaination.

** For P30 or small case ecu, make sure J4 is remove to enable datalogging. And for P28 or large case ecu, make sure J12 is remove. If not you will get connection time out error.
