wats guys i have a 99 em1 and im planning to go turbo, some guy is selling me a p28 wit hondata s300 for only 250 but just incase the guy is b.s. me how can i tell if the computer really has the program? maybe by opening it up?thanks guys

 

I highly doubt it has a s300. For the price is probably a s100/200. Check hondata website to see what you can look for.

 

The s300 system has to have a slot cut into the ecu for the usb port
