why would i need another ecu for my turbo kit? why cant i use my existing one? i was told i would need another, such as a p28, but what is the reason for this

 

ok i figured it out h: ....he meant i needed obd1, and seeing as how i have a 97, i would need an obd1 ecu to run hondata...but instead of spending all that dough for the extra ecu why wouldnt i just get an apexi V-AFC? what would be the difference between the two

 

hondata has way more tuning options than a vafc or any other piggy back
