    FRP tuning for 97-06 TJs

    Nothing is supported in JTEC 2004. The control of CO sensor 2 cannot be switched off. The computer does not open the menu for installing the updated software at all. We use HPTuners.

    What is difference: DOHC 16v SMPI (ED1) 2002 and Power Tech DOHC I-4 (ED1) 2003

    I want to replace the ECM from one Jeep to another Jeep. The old one is Engine - 2.4L 4 Cyl DOHC 16v SMPI (ED1) 2003-2004, and the one I want to install is from 2.4 16V Power Tech DOHC I-4 (ED1) 2002. Will there be a problem, what is the difference in the system? Maybe 16V Power Tech DOHC I-4...

    What is this?

    I had found one for sale, the company is in the USA, I don't remember where. The photo is from there. I will not change this item for now. It turned out that my gas pressure was correct. My jeep's problems are not from the wrong pressure.

    What is this?

    I'm not sure what the fuel pressure should be for a 2002-2004 Wrangler 2.4L engine. In one place it says 48 psi, in another place for 2001-2006 Chrysler and Dodge it says 53 psi to 60 psi.

    What is this?

    For 2.4L there is no second line. Only one line goes to the engine. Excess fuel is returned immediately from the pump valve.

    What is this?

    Unless a lot of fuel has leaked before closing the throttle?

    What is this?

    Low or high pressure would cause the exhaust to explode when the throttle is back?

    What is this?

    I will measure the pressure of the fuel system. I am trying to find out if this pressure, which I will measure before the rail, is the final pressure that reaches the injectors. If there is incorrect pressure, I will replace the pump and its valve.

    What is this?

    Yes. That's why there is a fuel valve regulator. And if high pressure reaches the rail, there is no other regulator to lower it? IIRC is not regulator, only pulse damper? Or if from the pump and its valve to the rail the pressure is lower or higher than necessary, there is nothing to help the...

    What is this?

    The pressure after the fuel pump must be 48 psi. Does this mean that the rail pressure drops from this regulator to some limits and the rail pressure must be, for example, 40 psi? What would happen if this regulator did not work properly?

    What is this?

    What is this? Fuel pressure regulator? Is it disassembled, regulated?

    2003 2.4 backfires on acceleration

    What happened to your problem? I also have a backfire in the 2.4L exhaust system. There are no stored codes, the jeep has no power and overheats the mufflers. The fuel mixture does not burn in the engine, but in the exhaust system.

    Overheating of exhaust system

    Yesterday we replaced almost all sensors and sensors on the engine, the car was repaired. When you reduced the throttle, the unburned fuel began to explode in the exhaust system. The temperature at the end of the exhaust system remained 300-400F. This morning he finally refused to start the...

    Overheating of exhaust system

    The problem is in a very poor fuel mixture. Spark plugs are white. The lambda probe 1 works correctly. I turned off the lambda probe 1 and the car went into emergency mode. The exhaust system temperature dropped from 600F to 500F. This proves my rightness. Diagnostics, nozzle flow measurement...

    Overheating of exhaust system

    Today we removed the exhaust system and installed a straight pipe. There is no difference from the previous situation. The problem is not in the catalysts, which are no more. The exhaust system overheats to 300C (600F) degrees. Has anyone had a similar problem?

    Overheating of exhaust system

    I do not know . Maybe they are the originals from the factory. The car is 56,000 miles away.
