Heres the deal…my car WAS Auto…converted to Y1 tranny last yr…now i recently swapped in a B20 motor w/ a skunk manifold… I have the original ECU from my auto , now its throwing a code 12 (EGR). Is my Auto ECU causing the problem???
That would be my first guess…the auto ecu would likely throw up the code because the engine you have now isn’t equipped with an egr…
Is the Skunk manifold auto compatible?
Automatic cars have egr but manual b18s do not. The egr mounts to the intake manifold so it was probably removed when you installed the Skunk manifold since it was fine before. Now the computer thinks something is wrong. You could try to reinstall the egr valve somehow or get a 5 sp computer. You also could try get your computer modified by someone like Zdyne or Hondata
