I have a problem. I just got my ECU in (PO7) and for some reason My car wastes alot of gas, is actually slower than when I didn't have v-tec? Sometimes When I start my car it will shut off If I dont rev it. And what about sputtering? Like I have to be reving it then throw it in first just to acclerate to maintain speed, becuase if not it just goes very slow until it picks up speed. then when I shift to second gear it makes like a weird (Prrrr) sound. Then If I throw it in neutral it backfires sometimes(like a loud pop) I have a 95 hatch Dx w/ a JDM D15B V-tec and just got my ECU (P07) from a VX. I have apexi N1 catback, and AEM intake. Can Someone Help me out? Thanks!

 

i think that ecu is for economy vtec equipped vx cars. What engine are you runnig?

 

JDM D15B

 

The P08 is the correct ecu for the d15b VTEC. The P07 is an economy ecu for the three stage VTEC-E system I believe.

 

get rid of that po7 and get a p28 before you damage that motor
