[turbob20bEj]

Hey everyone i have a b20b with automatic Integra transmission running a turbo  on a auto p75 ecu with the stock Integra tcu in my 95 civic ej coupe  . Iv just installed hondata s300 into it and everthing works great! Why do say it wont support automatics?  If i may ask? And if it not supposed to then why is it working ? I also have no codes ecu or tcu related! Just to let people know !
