I was reading a tread on mitsubishi & rx7 forum i while back where guys done it before on different cars "Not Ep" but it explains exactly how its done here with pics:http://www.rx7club.com/showthread.php?t=892101
interesting read.. i know this can be done on the emu by means of using the nissan nvcs system as a multi switching system, but wasnt aware u could do it with the emb.
