Im wondering what would be the best non-chipped ecu to use for my Jdm b16a2...i have the ecu that came with the swap and i also have the ecu from my old engine,93 sohc vtec automatic...for some reason the car starts up and idles better with the auto ecu??? is it just me? help me im a noob to the B-series.

 

best ecu would be p30. should be what came with your ecu

 

There is no JDM B16A2, but yes the P30 would be the ECU to use
