hey all. im running a 13bre with a e6k and im wondering how much i would benefit from upgrading, which is kinda redundant in a racecar. i know zero split is cool, but electronics arent my forte. thanks!

 

Will run and drive your car fine. Have had cars run for years with zero problems on a e6k. If its a race car anyways you don't really need close loop and better idle control and all the amenities of the newer ecu's

 

thanks man. good to know i can get better gas mileage with closed loop later. i can get about 23 24 now.
