On hondatas wesite they say that a s100B is 495 and that a s200B is 495. I have a 00 Civic about to be turbo, and i dont think that i will be tuning it myself but maybe after i learn more and become pretty knowlegdleable about tuning, would want to tune my car myself...so would it be better just to buy the s200B so that later on i can upgrade to datalogging and 3-step rev etc. But you can get the ROM Editor V3 software and then tune the s100 yourself. So what would yall do?

 

I bought the s200 for the same reasons you said
