Which PFC to order?

[aNskY]

i just called apexi to get the correct part number for my SR20... and they gave me part number (414-AN021) based on the ecu code that came with my motorset... however my dealer is telling me that ecu's get swapped around like crazy and to go by the actual pinout of the harness, but he's not sure exactly what to look for. i know for sure i have a blacktop, and the ecu that came with it is an E5. so what do i look for on the harness pins to get this right for sure?

haha just had the same question.

"If the E5 letters are marked on the ECU, it's RPS13 chuki model(middle term)"

Somebody confirm that for me?

its the same PFC cause mine reads the redtop and black top. except the S15 blacktop.
