Ea-81T timing


Recommended Posts

Aha ! The EA82T Series  One is said to be much the same as EA81T. One difference is the number probably only due to design differences as the younger is set at 20°

I have run it as high as 26° and ECU takes no control if spark at all as it is mechanical advance, plus vacuum advance/ boost retard vacuum cannister on the side.

And there is also the knock control module

Are you talking about the service manual supplement? If so yes. After looking again I found it. So for anyone else here it is. 
BTDC 15* +/-3 @800 rpm

I will get bad knock when its set at 15*. So set it at 11*+/-3 @800 rpm. Runs good but getting less mpg..
