AEM EMS and fuel level reading..

El Boricua · Jun 12, 2009, 06:00 AM

Can anyone tell me why the fuel reading with the AEM is out of synch..?
Even with a full tank (up to the nozzle) the fuel gauge doesn't goes up to the full mark. On the other hand, it start lighting up the empty light with more and a 1/4 tank (which in part is good, but it gives you the urgency feeling when there still plenty of fuel in the tank)....

Is there a way to calibrate this to make it more accurate ....?

Thanks,

Don't think so... the gauge reads OK with the stock ECU..!!

It's a problem associated with the actual AEM EMS, there is a pin on the ECU hanrness connector you can disconnect to minimize the problem, I just can't recall which on it is right now.
