I have a d15b1 from my ef hatch and swapped it in my eg hatch. I changed all the cables from the inside of the car so its OBD0 instead of OBD1. What would be the best computer to use? i already switched the tranny to an Si tranny. Later on im going to change the DPFi to MPFi.

Your only option with DPFI is the PM5 ecu.

Would i be able to chip it? and add fuel maps? or anything else? to run better?

Whats the point it is a d15b1, you are not going to make it fast. Use the stock ECU.

What would be the best ecu if i did the DPFI>MPFI?

PM9, I don't think there is another ECU that will run it at all. It is DPFI, I do not know antoher engine that is DPFI, you have to use the PM9.

Edit: just saw you were going to convert. Look over the EF forum and look to see what others use when they convert.

Ok thanks i appreciate it, im going to use the PM9 for now. I have everything for the conversion its just the wiring i need.
