Ive been looking into ECU upgrades for my car. I been doing heavy research on the S200 and S300 Hondata modules. All in all the s200 unit has the funtionality that i want which is....

*Vtec control
*fuel mapping to adjust for street situations and long drive situations
*rev limiter and fuel cutoff control
*datalogging
*expanded rpm range
*launch control

....the s200 has all these basic functions with plug and play simplicity.....but it seems that the s300 unit has all these features(im assuming) as well as some ither features....im assuming. So for the money(which i dont mind spending) which unit is more suitable or jus simply the better value??

 

the s200 is a great system. The biggest difference between the two is useability. With the s200 you need an eprom burner to "burn" new tunes onto the chip. The car has to be turned off to do this. With the s300 everything can be done in real time with the car running.

Hondata is not a piggyback it is a stand alone.
