No that motor was swapped into it. ex's and si's all came with a d16a6.

The stock ecu is the pm6, more than likely the car is running the hf ecu.

Okay I thought someone swapped that motor in.. kinda sucks that they did.... anyways the d15b6 would or should I say could run off the pm6 right.. becuz it runs shitty it runs rich... idles a bit higher... or how would the d15 run on the pm6

The d15 would run rich with the pm6.

Swap it out with a pm8.
