    Error Code P0513 means the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) has detected the presence of the immobilizer key (better known as ignition key) but fails to recognize it. If the ignition cylinder is turned on, the engine is cranked (but not yet started).

    I would start by changing the battery in the keys/remotes.

    There are already 6 holes in the pinch weld. Drilled 4 more and secured to pinch weld. But, dimensions and construction of the rail is very precise. Any upward pressure on the rail will push the whole rail length onto the chassis without bending the pinch weld. Due to the rail construction, side impact will not bend the rail, unless impact is very severe that should not happen in "normal" off road use.

    Latest updates. Had repair done on left side exhaust manifold. Studs broke off during cats removal. So new gasket, skim manifold and new studs.

    Then fitted the Old Man Emu suspension, with air bags inside rear coils. Before and after pics below.

    And the right hand manifold broke 2 studs and developed small crack. Crack welded up and studs plus gasket replaced, all well.

    It is a type of combustion chamber. Introduced by Dodge in 1953. Hemi is the short for hemispherical combustion chamber.

    Upgrade. The 5 speed gear box is now a 6 speed box. Used HP Tuners to activate 2 Prime which effectively added an additional gear. It also shows up in the EVIC message box. The rpm at 120km/h is also about 100rpm lower.
    Will see what is does to fuel usage.

    Ren, a 545RFE box. But must have the NGC4 ECM controller. That is where the software change is made using the HP Tuner.

    Well, back in Cape after about 2100km trip that included Pakhuispas and Botterkloof pas going up and back. Must say, this extra gear is very useful in kickdown and overtaking. It actually puts another gear between 2nd and 3rd, but does not reduce rpm in D.
    With the tune I have now, I constantly get over 7km/l, mostly about 7.6; but stay under 130km/h.
    Will see what the city driving will give.

    Exhaust manifold leaks!! Left side repaired mid Feb; 4 broken studs. Right side repaired beginning March; 4 studs broken.

    On returning from latest trip, I was sure than I could hear manifolds leaking slightly. Well took Jeep back to indy who did repairs. Found both sides again with leaks. Got Jeep back today. Did re-skim of manifolds, again new gaskets.

    Fault, some bolts came loose, because correct tightening procedure was not followed for the Eagle Head motor. The owner explained that he is sure his mechanics took short cuts since they never had comebacks on this before. I know him and get on well with him. No cost charged and no angry words.

    Will give feedback on the "fix".

    I noticed with the log recordings with HP Tuners that the fuel trims showed a problem. Will monitor.

    Now new task; replace whining power steer pump and flush the system. Next week.
