    OK - I am just going to throw this out there, I know and have heard all the arguments as to why you should not disable the factory alarm and I see people are hesitant to discuss it -

    Let's think about this - if the alarm operates by RF, then it it should be fairly easy for one to open the alarm brain and bypass the RF reciever replacing it with a simple trigger (perhaps wired to a switch or button - or better yet - a modern alarm)

    Why has no one done this yet - I bet one could make a killing offering this service to owners.

    Does my 95 355 have an alarm? If so it is not apparent.

    thanks

    Mine has a black key fob passed along from the PO. It seems only the lock & unlock works. I've been wondering what the siren actually sounds like, but without the PIN, I'm reluctant to try it. I dont have any other documentation on the unit.

    The 95 version does not have a European required immobilizer, which is referred to as an alarm in this thread.

    Who would be suing who and for what???

    If a person chooses to install an aftermarket alram/immobilizer in almost any other car on earth, the installers have access to information that allows the OEM unit to either be bypassed or disarmed so it will not interfere with the new system.

    Not only this but there are also scores of people offering immobilizer delete for many other cars by way of ECU flashing - honda, acura, BMW, VW, etc. etc. - none of them are getting sued - so how is ferrari any different (there are nowhere near the number of cars that these other marques have...)

    IF the immobilizer is not inside the ECU, I would think it would not require a reflash.

    The owners and insurance companies of every car stolen. I take that pretty serious as I own one myself and have no want for that data to be public. I did the job once for an insurance company, signed paperwork stating it was confidential and made them do the same. It ends there.

    We can agree to disagree on this point.

    I do see your point, but as I said there are much larger automakers out there and people are offering immobilizer deletes for them - you would think if any legal action was going to be pursued, it would have happened by now -

    I want to make myself perfectly clear here - I am not suggesting that anyone post "how to steal a ferrari"

    The operation that I am talking about would probably take way too long to be feasible if one was trying to steal the car.

    Not trying to create any argument here, simply stating that there must be a way - unless that way is way to easy and nobody wants that exposed...

    I thought about the idea also. Soon as my 98 is out of the shop, I will tinker with the box and see if I become succesful with it. If I do, its possible I can offer my service to those interested on a conditional bases. All information stays confidential, the box gets Fed Exed, it gets twicked and Fed Exed back to its owner. There will not be any online postings of ideas or ways to bypass any system. If you have all three sets of your fobs, you may want to follow up and just read on this. Those of you with a single set, we should way our options and think about being stranded in the middle of nowhere.

    In looking at it, it actually looks simpler than I thought, it just seems to be wired similar to any aftermarket alarm, it cuts the starter and the ignition or fuel pump - nothing to do with the ECU for the engine like on other cars (BMW EWS for example)

    We shall see what develops, and yes, keeping it to PM's as far as details is fine.

    This is already happening at the higher end installation shops. Owners with one black fob can find these higher end stores. They will take your black fob and install it in your car with the new alarm system say a wireless FOB in the pocket walkup to the door and the car senses you and you pushbutton start your car no key. They open your black fob and hard wire it and trigger it with their aftermarket electronics so that you get all the new modern keyless entry stuff with the OEM immobilizer functions and no more cr@ppy Ferrari alarm box (aka corvette box for 1/4 the price). So if you want to do it these new systems already exist for your old motronic 5.2 cars and above.

    It is indeed very similar to the BMW EWS, with the final immobilizer in the engine ECU.
    If the ECU doesn't receive the correct digital code, it wont allow the engine to start.

    This is what I came up with today, I looked into it (I was an installer for many years and worked in a hi-end shop that did a lot of F-cars etc.) I made some calls and determined that this is what is done -

    Basically we install the remote in the car, a N/O relay replaces the momentary switch in the remote and it is in turn wired to the new alarm - one of the aux. outputs triggers the OEM alarm.

    ***second option is to use a device that will apply a momentary pulse to disarm the system every time the key is turned to the "on" position, thereby disarming the system automatically (this would "obviously" only be used in conjunction with an aftermarket immobilizer)

    This eliminates the need to carry the remote and thus eliminates:

    - wear and tear

    - possible damage due to water, dropping or other physical damage etc.

    - loss of the remote (if you lose the key you can easily replace it, and the aftermarket FOB) since it is permanently installed in the car.

    I will be doing this ASAP! (since my car only has one red)

    Why not simply cloning your remote? Not expensive and you are safe.

    Because I only have one, so unless it could be done locally it'll be a long time to send to France...

    Plus I will still want to install a new alarm/immobilizer/pager system.

    OK. Good luck!
    Installing a new alarm which "press" a remote in the car is very poor engineering and certainly not the best way to decrease a failure rate IMO.
    Your second option is a much better solution, in the air for a long time : http://www.ferrarichat.com/forum/showthread.php?t=265498

    I am not really clear on which "solution" you are referring to, do you mean the jumpers for the challenge cars? Or the post by Taz stating there are two shops that can disable it?

    I was referring to the device which can emulate the digital code between the alarm ECU and the Motronic.
    Not too difficult to record the signal while the system is working, then to build a small device (basically a cheap microcontroler and a couple of components) able to reproduce the signal and can be put in place of the alarm ECU.

    I would like to have this device. Then you could turn the imobilizer on and off a you saw fit.

    But really Eric's clones are flawless and because of him I have put this alarm delete project on the back burner. It is just so much easier to have a couple of clones and problem solved. Thanks Eric!

    Gus,

    If you build one I'll buy one from you or I'll share in your development costs.

    This device is available for almost every other car on the market, is is the device that allows you to install a remote starter into a factory immobilizer car (usually cars with a "chip" key)

    If the system is similar to the BMW EWS, then maybe the immobilizer bypass for a BMW will work or could be modified?

    I think you are referring to the digital signal between the alarm and the ECU - not the RF signal of the remote itself?
