i've got an sr in my s13, ecu's are numbered 62 for redtop and e5 for blacktop. but the one i was sold by heavy throttle performance is a 63. i've never heard of that code and i am having problems with my car flooding. does anyone know what that 63 ecu code is for?

 

isn't the 63 for the auto tranny?

 

I doesnt matter if its auto or 5spd, they both work the same on the swapped SR's.
