yeah im a noob when it comes to the ecu. is there adifference between ecus when they are chipped? like if i buy a p06 ecu chipped with a b20 basemap will it be exactly the same as buying a p75 ecu chipped with a b20 basemap? im just wondering because the p06 originally came on a sohc civic and the p75 us from a dohc ls. just trying to figure out what ecu to get.

 

OBD1 ecus are the only ones that can be rechiped

 

I'm pretty sure that it would essentially be the same thing.
