I've just installed an H22a stage 1 JUN camshaft and adjustable cam sprocket using a P13 JUN ECU. My car stays running but my idle is at about 400 to 500 RPM. I usually have it set at 900 RPM. At what degree would I have to set the cam sprocket? It is now set at 4 degree. Could I still run it with the P13 JUN ECU or is it recommended to get a Hondata S300?
