Don't know about the emissions, however at that price whatever you need to do to it makes it worthwhile and still have change vs the quotes you got.

Yeah, I pulled the ecu, because it takes 5 minutes and is necessary to run the IDP plenum and 997 gt3 throttle body correctly.

From the year 2000-2005 the 996 model uses (2) different part number ECUs that are a different Motronic version from which we cannot delete the immobilizer system yet.

Well, on my 9th official day of 911 ownership, I already have a medium-sized disaster.
I sent my ECU to we well-known tuner via USPS. Long story short, USPS says they delivered to the correct address, tuner has no idea where the ECU is, never took delivery. I am of course still working with the vender and the USPS on this, but it's now been 5 days, and no one knows where my ECU is, so I am planning for the worst. I do not want to go into any further detail on that now, as I am still trying to resolve.
Yes, it was insured, but I am having issues with that end, as USPS says they did their part and delivered the package correctly. I will take care of that as it unfolds. Apparently there was no signature, I assumed there would just be one on an insured priority package.
Anyways, Porsche quoted me $4,975 for a new Bosch DME and the requisite programming to get me back running. I have a high-end shop in my area also putting together a quote.
As I mentioned, I have no idea (and no control over) what the results of the insurance claim will be. We've all heard the stories. My question is, if buy everything matching from the same car, a coupe 4S 6mt, the ECU, Immobilizer, key pill, and switched everything over, wouldn't that work? How would the car know the difference?
I am not trying to reprogram the immobilizer or keys, so why would I need the IPAS codes or previous car's VIN #?
Anyone have any suggestions or experience with this?
Thanks a ton. The good news is, for you guys anyways, someone is going to be getting a brand new, unopened IDP Plenum, GT3 throttle body, BMC filter and PC950 lightweight battery for dirt cheap...
ssssooo you owned a car for 9 days and pulled your ECM........................you are right by 2 quotes .............you have no idea . is this your first car
wow that situation sucks...
So are you now selling off all the parts you were planning to install, why?
This might help you out, its very cheap:
http://www.ebay.com.au/itm/Porsche-9...AAAOSw4CFYyKgT
Excuse me? This is my 3rd porsche, and yes first 911, which if we're honest isn't much different than my 986s. Approximately the 12th car I've owned including M3s and S4s...
Yeah, I pulled the ecu, because it takes 5 minutes and is necessary to run the IDP plenum and 997 gt3 throttle body correctly.
Why would you bother writing that, unless you felt insecure about your own abilities?
Because it's potentially going to cost me a few thousand to get my car running again, and I'm not sending my ecu back to a shop that may or may not have lost the first one, nor am I spending $1,700 on a custom dyno tune for a NA car. It's fast enough stock, I just thought I'd have some fun and if I could give it a little more pep for just $2k in all parts and tune then it would be worth it.
Correct RoW configuration you couldn't use the steering lock component but you could still possibly salvage the key barrels. Don't know about the emissions, however at that price whatever you need to do to it makes it worthwhile and still have change vs the quotes you got. Anyway best of luck

I'd see if you could return the 82mm plenum and get the 74mm standard size one, no tune required.
Also BMC filter is a waste of time IMO no gains to be had from it, hard to clean correctly and the risk of MAF damage from oil. Others may not agree.
Yeah, I had mixed feeling on that too, but it was recommended to me by two different shops, both of whom were not also trying to sell it to me, and I figured at the very least it might help to make a nice noise
Is that the 74 or the 82 that they recommended? Guessing they initially recommended the 82 and now just the 74?
All for the Ipd (I have the 74mm one) don't know about the 82mm I'm sure it has its place.
I want the 82 but I don't want to use the Ipd rubber hose (opting for the factory look, even though very few eyes would actually see it) but you can't have your cake and eat it too!
I dont think the ipd necessarily adds any sound, removing your helmholtz resonator box yields more intake noise. I haven't heard of anyone using an Ipd plenum for sound only performance.
Also from seeing the Ipd 82mm video they recommend 82mm plenum + gt3 throttle (obviously) + aftermarket/upgraded exhaust + tune. Quite a shopping list!
I don't quite understand why you don't want to just get a used DME (with vin) and have the car towed to Porsche dealership and installed . And yes they will need to get the IPAS codes for both your car and the donor car (hince needing the vin #).
Sigh, this is exactly what I am asking for and was hoping to find out. Are you sure this can be done? Porsche dealer didn't seem to want to go the ebay DME route. I have AAA, so towing the car won't even cost me anything. Can I buy any 996 or 986 DME? Does it have to be a 3.6? Does it have to be USA? They are not the same part number, but someone I trust told me it actually doesn't matter.
I was referencing the BMC filter in terms of sound.
My car has a fabspeed exhaust on it, I was excited to try out the larger throttle body and get rid of the airbox muffler. But we shall see. If it only costs me $400 for an ebay DME and $540 for porsche to program it (plus tax!) I will probably keep all the stuff and try again with a different tuner.
I didn't like the sound of the BMC filter I had, I ditched it.
Jake one of the most reputable M96 builders actually noted not to use the 82mm unless you step up to a 3.8L engine (not sure if that comment meant to stay away unless you tune though).
If you're referring to the AUS ebay one the dollar is in your favour so it will cost you even less. Let me know if the seller wont post internationally I can help you out if required (tracked and insured of course) too soon? Mi scussi!
Nah must be without a tune, all the 3.4 cayman/box guys use the 82mm. Sam at EVO told me you just need the right file to get the 82mm to play nicely.
haha! Appreciate the offer...... but I don't know how'd I'd mount the DME upside down
Fair enough, might have meant don't do it without a tune. Hopefully if he comes across this thread he can confirm although he hasn't been active/posting from what I have seen. Might be preparing for his M96 classes. Maybe someone can ask and report back!
From my reading going 82mm ins't as popular as using the 74mm plenum which is what most seem to be using (like me).
RE installation of an AUS DME just install it under your headliner, will be all good mate! haha
I am retired from Porsche dealership .. yes I can be done. Do they really want to do it?no.Can you make them do it? no. They do not like to use used parts or E-bay parts . Why? Because sellers of used car parts and e-bay sellers do not stand behind their parts, sure if its bad they will give you another one, but if you end up with some strange code or weird problem, can you get any support ? NADA.Porsche would not only supply another part, but would pay for labor and reasonable diagnostic time, if they are involved any tech info or support.
Having a good relationship with your local dealership can be very helpfull in cases like this, could save you a ton of money.
Yes It has to be a USA part, yes it has to be for a 996 and not a 986. and yes it has to be for a 3.6 N/A.
If I were you I would visit the dealership, ask to speak with a tech about a technical issue on your non-running Porsche before you have it towed in. Talk with the tech and be certain he says he can do it and is comfortable doing it. Because they can be bricked by putting the codes in wrong, and with it being used parts you will have to take full responsibility for anything that goes wrong.If you plead nicely and take full responsibility, they will probably help you. I would not elaborate on USPS and the other shop losing your DME, the less they know about that the more likely they will help you. Just say the DME got lost when you sent it for a tune..no more than that, because they definitely don't want to be involved in any squabble !! Good Luck !
Used DME,s are all over the place for less than a thousand, You have to have it coded by the dealer to match your security module but that should also be less than a grand. You can also send it to ECU doctors in Florida and they can match it.
Wow, thank you, just spoke with them, they were great.
I actually do have a very good relationship with the guys at Burdick Porsche here in Syracuse. They have been very nice and provided excellent service to me, even though I have just been a 986 and now 996 guy.
So right now my options are:
1. Buy correct ECU on ebay, send to ECU doctors with my immobilizer and key pill, they will program and match for $375
2. Buy ECU, ship car down the road to dealership, have programmed at Porsche dealership for $570, if I can convince them to do it. This seems like the best option right now, as it does not involve shipping the ecu again ha ha.
3. Buy all new from Porsche for $4,975
Looks like either way I may be able to get out of this for $1k-1.2k, while I battle USPS for reimbursement.
Appreciate all the help so far.
Dan, I found another one from your wonderful country
http://www.ebay.com/itm/engine-ECU-P...MAAOSwAANY5O3E
But for some reason, it's all written in german.... �\_(ツ)_/�
wow that sucks, you are screwed either way
and of course right after you do all of this your original one will be found ... at least thats what would happen to me with my luck lol
Damn, just found the original tune for the car here for $1.99:
http://carprotuning.com/Tuning-Tools...5151.Original-
I wish I knew how to use a hex editor and interface with the DME
Thanks for your recommendation and yes, we can definitely get the IPASS codes and program the ECU Set for match your car's VIN #.
The only thing that you'll need to get is the "key blade" from the dealership in order to match your car's ignition switch and door locks.
Unfortunately I cant help with that one, nice character use though! Surely with those character skills you can get the ECU HEX done!!
Yup correct!!
gold star for you sir!
I'd like to dabble with reprogramming ECUs, I briefly looked into instrument cluster programming looked fascinating. So does building your own PWIST2 from Bosch parts!
The only thing I can add is by sending it to ECU doctors you eliminate the stink eye the dealer will give you. They are by far the best I have found for repair and modifications to ECU's and other electronic modules for Porsches. Also they will test your used DME so you know its good, they canalso flash their performance tune to the ECU.
ECU Doctors can also eliminate the drive block in the ECU, I had them do that in my race car, you only have to send them the ECU not the Immobilizer module.
I mean I just got off the phone with them and they very specifically told me they needed the immobilizer, new dme and key pill. So, I don't know?
I would totally love to be able to eliminate the immobilizer, and yeah, I don't see why you couldn't just program it out or physically bypass it. Would be great to not have to deal with it anymore.
Just to clarify;
Only in the 996 Porsche model from 1999 is that we can bypass the Immobilizer "Drive-Block" system from within the DME/ECU itself.
These are the ones that use Bosch Motronic control units with part number 0 261 204 605 (or Porsche part number 996.618.601.04).
They look like this:
From the year 2000-2005 the 996 model uses (2) different part number ECUs that are a different Motronic version from which we cannot delete the immobilizer system yet.
Those units look like this:
And from the notes and previous posts, I think your model is year 2000 or higher.
That's why we cannot bypass the immo in your car, but we can fully program both the ECU and Immobilizer to carry your car's VIN and specific programming parameters.
I did!!!
So, after buying a second ECU on ebay, and sending it to florida for the ECU doctors, Sam Stone from EVO Motorsports in Phoenix called me, 11 days after my ECU was delivered, saying they found it.
Turns out it was delivered to an unattended mailbox at the complex EVO is operating out of. Mr. Stone himself tracked down the actual delivery guy asking him where the ECU was and was met with an "uhhh....". Sam had the guy go and open all the mailboxes at the business park and sure enough, there mine was, delivered to the wrong box.
I got everything back, and installed in the car, and I couldn't be more happy! Huge thanks to Sam at EVO for providing great service and an excellent tune.
82mm 997 GT3 Throttle body installed, IDP plenum installed, BMC drop in filter installed, Fabspeed cat-back installed.
Interesting to note: I got the ecu back with the tune before the plenum came in, so I had to install the tuned ECU without any of the other mods it was tuned for, namely the throttle body. Sam assured me it would just run a little rich, but would be good to go. Even without the tbody and plenum, the tune alone was worth it. MUCH better throttle response and a smoother power/force delivery. I would estimate from butt dyno 10 hp and +10 ft lbs for sure.
But then when I got everything together OH MAN! The tune really tied all the parts together, the car sounds GREAT now. Before there was absolutely no induction noise, my biggest complaint over my boxster. Now it sounds like thor himself activating the throttle, there even more power and torque. I would estimate no BS, +25-30 hp and +20 ft lbs, but I will confirm on a dyno in about a month, where I reeeeeeally hope I'll hit 285-290+ whp
Later, I took it out on the highway (totally in mexico) with my boys in a 2007 B7 S4 6mt and a 2008 C6 S6 5.2 V10 tip with 340 hp and 435 hp respectively, and I absolutely crushed them (ok maybe thats an exaggeration, but I was walking away from them nicely) in a 2nd - 4th gear pull from approximately 35 - 100 mph. (Interestingly, it was dead even through 2nd gear, and only started pulling ahead once in 3rd and into 4th).
I have PSS10s coming in 7 days (thanks TH motorsports!!!). At that point the car will be converted to RWD, I'll do new plugs, and an underdrive pulley. Install a PC950 in the frunk for added lightness, then I will have the car corner balanced and aligned and dyno'ed in new jersey. There's a thread on here showing the gain from AWD to RWD is 12whp and 10ft/lbs and minus 70lbs sprung weight.
Really hoping for 290 whp, and 3200lbs empty (sans drive and fuel).
Glad everything worked out for you in the end my friend! Not surprised to hear you felt that much improvement, these cars have more potential than people give them credit for. Nice to see we were able to contribute to the project with our catback!
