Here is the break down of the SR20DET ECU's

E5 is from a 94-96 180sx black top 5 speed

E6 is from a 94-96 180sx blacktop automatic

WC is from a 94-98 S14 Silvia

62 is from a 91-93 180sx or S13 Silvia 5 speed

61,63 is from a 91-93 180sx or S13 Silvia automatic

J4 is from a 97-98 180sx Type X 5speed


My question is that I have a Kouki Type X SR20DET motor but I am not certian the ECU that came with my motor is the correct one. The only identification on the ECU is a little red sticker next to the harness plug that states it is a G90. There is hand writing ont he ECU it self and MT is circled. Will this ECU work with my black top? I am still searching the net for anwsers but if you know if I can still use it please let me know.
