    We use the Durametric system in the shop every day, generally without incident. Owen is trying to walk you through a firmware update which should resolve your issues. Did you try what he suggested? We looked the other system and found it lacking in several areas, which is why we stayed with Durametric, which has about 80-85% if the functionality of the factory PIWIS system.

    Most Boxsters came with one or more empty slots in the horseshoe trim panel, and most switches are simple on/off types.

    Welcome to RennTech I have to ask a question: Is this legitimate Durametric cable, or one purchased cheaply online?

    Welcome to RennTech Unfortunately, there are not a lot of options on this as most rebuilders don't carry "ready to go" exchange sets in stock as there are not a lot of these cars about, so demand is limited. That limits you to either buying another set or parking the car for a few days while someone goes through yours.

    Sunset Porsche is a board sponsor, and offers some of the lowest parts prices you will find anywhere: Sunset Porsche

    While it is never a good idea to start one of these engines if you know or suspect the cam timing is off, once you get beyond around 12 degrees you are in trouble.

    Sometimes you have to cut the bolts away and press out or drill out the stubs and replace them. Other times you can cut away just the nut and stave the studs. When they really get nasty, like daily drivers in the Northeast with tons of salt on the road, you don't have a choice. Some have taken to replacing them with stainless steel.

    Welcome to RennTech Did you either recently clear trouble codes on the vehicle, or disconnect the battery?

    Activating the ABS/PSM pump and control system while bleeding is only required if air has gotten into the control network. During a normal maintenance flush, it is not required.

    Lithium based batteries will not quickly spread into the SLI (starting, lighting, ignition) applications for two profound reasons: The exsisting recycling chains mandated by the EPA cannot recycled lithium based batteries as lithium poisons lead and makes it useless for batteries, which is by far the largest application for recovered lead. That means lithium SLI batteries would require a totallly separate recovery system, which is not economically feasible. Lithium based SLI batteries are expensive, making them unattractive replacements in a mareket where car owners tend to show very low price elasticity (read most will buy the cheapest substitutes they can find).

    The fuel pressure test port is under the engine cover (which needs to be removed). step. Once you have the cover off, the "fuel gallery" is the y-shaped tube (carries the fuel around the injectors) that runs on both sides on the intake manifold. It's the only silver metal tube there. On the very front ends of this y-tube, you will see black twist-off covers (similar to those found on a tire valve stem). Remove these and you can access the relief valves (they look like the inside of a valve stem). off, the "fuel gallery" is the y-shaped tube (carries the fuel around the injectors) that runs on both sides on the intake manifold.

    What you should be doing is the fuel system test I suggested. If you cannot do them yourself, take it to someone that can. Aimlessly swapping out expensive parts is only going to make your wallet easier to sit on.

    You need to start by running a fuel pressure and volume delivery test.

    The biggest advantages of AGM technology are their vibration resistance (a major battery killer, particularly in cars with stiffer suspensions), deep cycling recovery capabilities, superior cold cranking, longevity, and total lack of corrosion, which is critical on Porsche's due the battery locations. We have customers that are regularly seeing 2X life expectancies with AGM batteries, with absolutely no signs of any corrosion in the battery area. Their ability to be mounted in any position is a neat feature, but one that is rarely used; but their other capabilities are something owners can utilize every day.

    Good grief! A shorter list would be what is still working, which isn't much. I would approach this with a great sense of trepidation as cross wiring or shorting circuits can end up permanently damaging some of the myriad of electronic controllers in these vehicles, which means they still will not function once the wiring is corrected. In many cases, your Durametric will not be able to recode the modules, even if they are still in working condition, requiring the use of a PIWIS system. And if they are irreparably damaged, the PIWIS will not be able to save the day either. I'm afraid this may turn into the perfect example of a money pit, and a poster child for why those who are not equipped to work on these vehicles, or do not understand their systems, should not be allowed anywhere near them. It sounds like what they did was to butcher a fine vehicle out of ignorance or hubris. What was originally at fault is probably now hidden behind the damage they created. Good luck.

    Any sufficiently advanced technology is indistinguishable from magic............

    Welcome to RennTech. I would check the dash controller, it may not be sensing your cabin temperature correctly. There is also an air temp sensor in the dash that may also be the issue.

    The car's charging system is fully capable of charging an AGM battery, as are most battery maintainers and chargers. AGM batteries charge at a very slightly higher finishing voltage than a flooded cell battery, but nearly all chargers will get them to full charge, it will just take a bit longer.

    The factory dash layout diagram (below) does not show that symbol, so you may be loosing that display:

    You are both overlooking a simple fact: Boxsters have cooling system volumes way in excess of the vehicles you are comparing warm up times with. WIth the radiators up front, and long cooling lines running nearly the length of the car, you have a lot more liquid to warm up when compared to a conventional engine location layout. How fast a given heat source can warm up a volume of liquid is dependent upon how large that volume is.

    I'd also check the crankcase vacuum level to see if your AOS is on the way out, which leads to excessive start up smoking. Do a search, been covered multiple times.

    This coding will require either a PST II or a PIWIS.

    Grant, by your own admission, this engine had a lot of bad bearings when you pulled it apart, so I am not at all surprised that the IMS bearing was a bit loose with metal running around inside the engine. I would also be willing to wager that if a DOF had been in use, it would have probably been even worse as you would have been needlessly pumping debris containing oil directly into it, rather than the mist based oiling system that the LN uses. Open bearings are all susceptible to oil born debris; oil fed bearings are even more so. We have taken apart multiple factory engines with the OEM sealed IMS bearings in place that had suffered rod or crank bearing failures, and every one had resulted in some level of damage to the IMS bearings, so it is not the LN bearing not holding up, it is the debris circulating in the engine that tears up the IMS. This is the primary reasons that shops pre qualify every engine before doing an IMS retrofit; if there is already metal in circulation, the new IMS is not going to make it, no matter who's IMS bearing it is.

    To lay a couple of false "old wives' tale" to rest, the use of thread lubricants like ARP Ultra Torque, penetrating fluids, or anti seize will never cause fasteners to come loose; the only thing that causes that is the fact they were not torqued to the correct specs in the first place, or were dry or unclean when they were assembled. And before you ask, the use of any of these compounds will not cause over torqueing of the fasteners, but the assembly of dry or rusted fasteners will cause under torqueing and the potential for fasteners to come loose at a later time.
