Drive Box bypass
 


Last year I had trouble with the computer immobilizer. Cleaning it helped but it does not stop rust. Is there any way to bypass the anti-theft module under the drivers seat on Boxster racecars?

Battery is strong, turning the key, no starter, no ignition.

try this question over on renntrack.com
that's JUST the racecar folks over there

Jittsl 04-20-2012 11:20 AM

Yes there is. A company called Specialized ECU repairs in Florida can provide you with an ECU that does not need the immobilizer. They are not cheap however. I think you will find them at Specialized ECU Repair, Replacement, & Testing - Restore or Exchange your Electronic Control Unit (ECU)

Can't you just get the ECU re-flashed to remove this function?

Immobilizer bypass
 

Thanks Laurie,
That is exactly what I was looking for, remove and dispose.

The Dealer quoted me $3,000.00 to replace the computer under the seat with reprogrammed keys. I saw a car last week (2001 from Kauai) that actually cost $3,100.00 to replace the box. The place that you sent me and I otherwise did not find in Google search, wants only $675.00 to bypass the immobilizer by adding a chip that emulates the immobilizer signal so that the car will start. About 25% of dealer cost.

Jittsl 04-21-2012 05:48 AM

Happy I could help. You could also look on eBay. Often you will find a package of ECU, immobilizer and key for $600.

MaxD 04-21-2012 11:28 AM

Adding a chip? I bet you can get a ROW flash that eliminates the immobilzer for around that price.

From Pedro's website The DME

For special applications, such as race cars, we can now eliminate the immobilizer function, allowing the driver to not need the key to start the car.
I'm sure Brad can point you to a resource as well. It's all in the software, adding a sim is not a good solution.

Jittsl 04-21-2012 08:45 PM

I believe they actually replace the chip that reads and runs the immobilizer system rather than "adding" a chip. I have no idea weather it can be flashed externally or not but I suspect that they are effectively flashing the chip to build the replacement.

I guess $675 to make something NOT work seems expensive to me:)

Ecu Doctor
 

The EcuDoc’s bypass emit’s a signal that tells the Ecu that it is on all of the time. It does not “Mimic a recognized key's RFID and in order to supply the info when 'requested' by the in-dash RF transceiver security system.” EcuDoc puts something under the CPU, which emulates the Immobilizer Signal for the car to start without the remote's input. Ecudoctors

Pedro says he “can now reprogram a DME to completely eliminate the immobilizer and all the wiring associated with it.” However, with the Pedro cure you lose your windows working. But Pedro suggests:

Try removing the driver's seat and then the CLU.

Disconnect it from its harness, remove it from the car and open the case.

Remove the printed circuit board and dunk it in a shallow recipient and cover it with isopropyl alcohol.

Shake it well so the alcohol penetrates all the spaces, in particular between the chips and connections.

Then, let it dry. You can accelerate the drying by using a hair dryer in the cool mode.

Dry out the inside of the case if it had humidity and put everything back together.

If it was water causing the problem, it should now work fine.

We have saved many CLUs this way.

Pedro on CLUs

Pedro makes it sound like the Clu is different than the Immobilizer, but I only remember one box under my seat. In this bypass scenario the original system might still work if the immobilizer bypass failed, because if it did not get a signal from the bypass, it could still receive the signal from Porsche.

Just like life insurance.

The Porsche dealer says it costs $3,000.00 to replace the drive box with new keys and installation. I have seen a Kauai car where they paid $3,100.00 earlier this month. Immobilizer replacements are a lucrative side business for dealers because they are covered under comprehensive on most auto insurance policies.

MaxD 04-25-2012 05:08 PM

Good info Sumflow.

Leave it to someone in Florida to have the method to resurrect a repeatedly wet control module.

One question - Is this car still street driven or is it a dedicated racecar?

Sumflow 04-25-2012 06:04 PM

Racecar spelled backwards is still racecar.

The short answer is - Yes, there is a difference.

You really don't need the Central Locking Unit, Imobilizer or windows that roll up or down on a racecar. Read the rules of your class then rip out everything you can, you can always add weight back later.

The box under the seat has two control units in it.

Sumflow 05-02-2012 03:46 PM

Real racing
 

The car in front at the finish wins. That is if the theft control module will let you start the car in the first place.

I don't see why a car would need a Central Locking Unit or Immobilizer on the street or the track. As long as the windows still worked. You could rip out the other stuff and go undetected on the street and track. Especially if its only real function is to lock the driver out of there own car. I don't see why it matters where the car is driven as long as you finish in front. These boxes do not help us do that.

What I thought you were going to get into was the philosophical, "Is this car street driven or is it a dedicated racecar?" Which of course leads to the car being a street driven dedicated racecar, used for pleasure as compared to menial transportation. Dedicated to having fun and winning the occasional dice under natural conditions. Real racing is street racing against strangers, with all of its unknowns and unexpected thrills thrown in. No one is fooled, racing under some supposed self appointed authority, on an artificial simulated street is "pretend." It is just make believe racing.

* Auto racing began 5 minutes after the second car was built. ~ Henry Ford

* A racing car has only one objective: to win motor races. If it does not do this it is nothing but a waste of time, money, and effort. ~ Colin Chapman: Inside the Innovator

Five minutes after the second car was built there was no authority, no fake road courses, but there was real racing. Real racing came before, and is not dependent on authority or closed circuits. The racecar build objective is to finish in front, not just finish in front with some parental organizations approval, on a phony course. Why do you enjoy passing?

While this has nothing to do with your drive box problems, please don't street race. You post indicates that street racing is the only true race. Just last Christmas a 7 year old girl was struck by a car in our town when two clowns were trying to look cool street racing. Her parents later were forced to pull the plug when her brain activity ceased. There is a reason why racing is sanctioned under authority and practiced on closed circuits.



As for your belief that anything other than street racing is fake, I suggest you try your hand at F1, Gt3, Lemans, or hell, even the much criticized Nascar. Come back when you win. Yeah, anyone can mash the peddle and go fast driving on the street, but it takes refined skills to be a competent and skilled driver on the track. We all have our own opinions of racing which is totally one's prerogative, but I assure you it is no "pretend" or "fake" skill on the track. You truly crossed a line when you called these pros that could and would leave you in the dust in any race, "phony."

Not phony racing on the track. But the track itself is a fake artificial road.

Yeah, that is something any rational person can agree upon. Track conditions don't reflect upon ideal every day conditions. Just a misunderstanding you could say. ;) Nonetheless, I urge others not to drive recklessly in public conditions.

This thread is somewhat hijacked and should go back to helping out the poor guy's drive box. Sumflow, please keep us updated, as I am interested in finding out what solution works for the faulty drive box.:cool:

Sorry Sumflow but you just don't get it. A racetrack is an arena where two or more gladiators can duke it out without taking out someone's innocent grandmother or 4 yr old daughter in the process. It's simply a mayhem containment vessel. :) We don't do cage fighting in our momma's kitchen, and we don't go racing where someone's little precious might be walking home from school.

Racing on public roads is just :chicken:

Gladiators arena
 

I had a neighbor racing at LeMans, and while he was waiting for his car to come in, a chain of events led to 83 speculators deaths. Is that what you mean by an arena for gladiators?

The only way you can be sure your grandmother and kid will be safe is to have them watch the race on TV. These events happen because track owners are only concerned with making money. Any thing track owners do for safety is because they are forced to do it, and they drag on and delay as long as they can.

Yes, that was a tragic accident. What year was that accident at Le Mans? 1955? Has anything as terrible as that happened since? In 1955 they still ran a foot race to their cars for the start and many didn't even wear seatbelts. Those spectators knew there was a race going on and volunteered (paid tickets) to be there. They weren't just out walking their dog on a country road at night.

Yes, safety has come a long long way in 1/2 a century and race track owners have made it much safer for both drivers and spectators. It is an excellent place to hold a speed contest unlike public roads where you cannot control who else is on it. Is it still a dangerous sport? Racing is always dangerous. Don't get it twisted Sumflow. Race tracks are about controlling who is on the track and containing the mayhem. It's not about corporations at a local level at all. When Penske or McLaren calls you up to race for them... THEN it is about the money. :)

I still have hope for you yet. It took me the loss of two friends and one in a permanent wheelchair to figure out how truly :chicken: street racing is. Perhaps you will figure it out before your own sister or daughter is killed by someone you know who is just out doing a little "real" racing in your neighborhood. :barf:

Permission to start
 

Porsche does not have anything called an Immo Box or an Ecu in the technical literature, so don't stay up all night trying to find it. I don't know what this picture shows. The computer under the seat of a Boxster is called a Drive box by Porsche. The Drive box chip contains one control module for the immobilizer, central locking, and alarm units. My Drive box was wrapped in plastic over a year ago to protect it from water, it has not been wet. It did not show signs of corrosion or rust. It was not broken or dirty. In the boot secured by a few easy to reach bolts, and the wire plug in harness, is what Porsche calls a DME (digital motor electronics), or a ECM (engine control module). Both showed clear codes when tested by the Ecu Doctors equipment. Which tells me that just because its shows clear at your dealer, does not mean it is clear. In my case I saved a hassle, by not have the car towed all the way to a dealer to find that out, before we sent the parts to the Specialist. What they are doing is giving permission to the DME to start the car.

My Drive box, DME, and Transponder in the key, after a week long trip with UPS arrived in Florida on Friday. They started work Monday morning, opening at 9:00 am, they fixed it and were preparing it for shipment back to me by 10:00 am when they called. It is taking ten days for UPS to bring it back. In a week I will see if it is plug and drive.

I want to thank Jitts for linking me up with Ecu (whatever that is) repair, in the second reply in this thread. And not sending me on some Wild Goose chase with no links.

Jittsl 05-23-2012 11:09 PM

Anytime. Hope it all works out for you.

In my case (for my race car) they built me a replacement DME that had no dependence on the Drive Box at all. My ECU does not wait for a signal so I was ale to remove the drive Box and the key. Works great for a race car and saves a bunch of weight.

Do you have more details on this, as I want to do the same in my race car.
Did they just alter your stock box or supply you with a new one? Can you still push custom programs to it like the Softronic to go with other engine upgrades etc? And can I ask what it cost?

Jittsl 05-24-2012 05:08 AM

Contact ECU specialists for pricing (I provided a link in my first post on this subject) I honestly cant remember. It wasn't cheap.

In my case they provided me with a replacement DMI and I sent them mine once it was installed. I think I paid some sort of deposit.

I know that the ECU in my case is absolutely stock (as it has to be for my class) but I believe that there is no physical/programming change made to the ECU component. I would therefore believe that you should be able to make any changes to the new box that you made to the old box. You can probably send them your current box (if it is already modified) and ask them not to alter it. The alarm system and the engine control functions are in a shared box but do not actually share componentry or programming.

See the the second reply in this thread from Jitts. They put an emitter under the DME that tells it it is OK to start. It costs about $675.00

It does not matter if it is your DME


or if you do an exchange.

Sumflow 06-14-2012 01:00 PM

Result!
 
Plug and drive. Car starts and runs with key transponder removed and left at home. Nothing else has been removed. Drive box is still vulnerable to rain but will not effect starting when it gets flooded.

Result

Ecu asked to know what I HATED or LOVED about the service.

My reply to Jorge's questions:

I don't believe in hate. But the most annoying thing is hundreds of drivers who respond like empty-headed cheerleaders, “Hooray my car runs.” And do not give any useful information to the people who waste there time reading this dribble, who want there cars back on the road pronto!.

My April 20th online request form to Ecu Doc was not answered. I filled out the form requesting Ecu repair two weeks later on May 4th 2012. The UPS clown squad did not actually pick it up until May 10th. It would have already been in Florida if it was sent priority US mail on that Friday May 4th. If it had arrived in Florida on that Thursday May 10th, when they picked it up. And they fixed it the next day as they did later. It could have been back here in paradise before it was actually delivered to Oakland Park on May 17th. UPS # 1Z50FR219049805824. The DME did not get back here until May 31st UPS # 1Z50FR210351523029. Two weeks later than any competent firm could have delivered it.

After fixing my part, Ecu deliberately handed my DME over to UPS knowing it was going to take an additional ten days, when probably for less money, they could have USPS priority mailed it to me in four. Maybe I did not make it clear that my car was down. Let me rephrase. My car is not running and I want it back on the road as soon as possible!

Boxster Owners
Porsche does not have anything called an Immo Box, or an Ecu, in the technical literature, so unless you do a lot of guessing you will not find it. Porsche calls the computer under the seat a Drive box. It contains one control module for the immobilizer, central locking, and alarm units. In the boot is what Porsche calls a DME (digital motor electronics), or a ECM (engine control module). What Ecu Doc can do is bypass the need for your DME to get permission from the drive box and key, to start your car, by deactivating the key transponder’s function. The transponder signal is intercepted in the trunk, without permanently removing or disconnecting the Drive box. The transponder can be removed from the car. For street use you still must leave the Drive box vulnerable to rain water, under the seat. The ECM stays connected to the starter, fuel injection and the ignition but is no longer connected to the drive box if it ever was, or transponder. You have to wonder if Ecu knows what they are doing using a picture on there web site that shows them all connected together after the conversion?

After finding out about Ecu Doc from Laurie over at 986forum Drive Box bypass I still could not find this company on the Web. Pelican did not have it or Google, unless I specifically used the Ecu name. I did not know there name before, and Porsches do not have a Ecu, so how could I have found them?

It is a good thing that Jorge Morales can be reached through this forum. Upon completion Ecu gave a Repair Summary with a link for additional tech comments that goes nowhere. It does not summarize what we discussed on the phone about the procedure or contain any useful information. Repair was plug & drive, key transponder no longer active.
