Its time to get my car BAR'ed but I have one small problem. I have one CEL error, Code 91 for the Fuel Pressure Sensor. But I am getting ahead of myself.

I have a 96 Dx with a B18C Type R engine. Now in order to take my car to the referee I have to swap out my JDM ECU with a USDM ECU from an Integra Type R. Only problem, because I have an 96 Dx the Fuel Pressure Sensor is reading the wrong voltage for the USDM Integra Type R ECU.

Now there are a couple of ways to fix this:

1. Swap out the gas tank with any Integra.
2. Hook a potentiometer or resistor up to the ECU to trick the CEL to read the correct voltage.

I wanted to go step to, but no one I know has the instructions on how to correctly wire up the ECU.

I really need it BAR'ed as soon as possible. I have an out of town license plate and the registration has expired. And I really need to register the car in the good state of California.

Can anyone help
