Thus far so very good… preparing big career for our household… acquired a traverse and three months afterwards the timing chains failed… hoping we can easily pay for for getting it sent and set up. Thx
All ECU’s use different sensors to determine load. However the tactic utilised varies in between engines given that the Silvertop takes advantage of an easy Vane kind airflow meter although the Blacktop makes use of a far more intricate vacuum (MAP) and throttle position (TPS) for much larger throttle openings where by there isn't any vacuum.
I used to be gonna return the engine, but ultimately, Greg in the JJsmotors staff talked me into holding it, and don’t regret it in any respect. seven months in as well as motor is functioning effortlessly for a motherf*ker
