    Adjustable cam gear for 7a

    Building new AAN motor and putting 7a cams. Do i need adjustable cam gear or do i use original AAN gear? If i need it what do i put it on approximately fist start? Retard or advance? Same orientation as standard i guess. Want to make as little work possible for the guy mapping the car.


    Will run Vems with standard hall sensor

    Hope this is enough information

      Yeah, I belive you need the adjustable cam gear for the exhaust cam and the adjustable cam sprocket for the intake cam to setup the cams properly. With stock marking you get a quite laggy setup... You can first try to adjust something between 0,8-1,2mm for the exhaust cam and 1-1,5mm for the intake cam at TDC.

        if using AAN/ABY ecu then you need cam pulley with hall sensor, Dahlback do adjustable ones.
