I'll try to figure out how much the tax is first. The information I found was a little fuzzy, so I gotta search a bit more. Filling in a low value might be detrimental to the shipping insurance. If the package were to be lost I need to be able to replace 11 defloaters. If the tax percentage is acceptable it may not be an issue to enter the true value, as the cost would be split amongst all buyers.

Does anyone here know how about import duty regulations for the US?I'm wondering if, and how much import duty one would have to pay to get all of the defloaters imported into the USA in one box.It's probably dependent on the value entered on shipping. I want to buy ensurance on the shipping, so I think I have to state the value of the package truthfully for it to be covered properly.

Good info, I'll definately check it out. It would save me a lot of time if I could just order those. Thanks

That's more or less the reason. Although I didn't know about it failing emissions tests. You're the first to report that. I can determine which option it will have solely by wiring it slightly differently. Without the on/off switch the defloater can still be disabled relatively quickly by disconnecting the rpm feed, although you need a small spanner for the nut on the ign coil. Toolless disabling can be done by disconnecting its bosch plugs, which can be done in about a minute. (Or 10 secs if you've done it alot like me :p )

Haha not quite yet :p Uni hit me full force again, but I did find a little bit of time to work on tge defloaters. Currently I'm adding the rest of the electronics to the boards. Ill take some more pics when I finish adding the electronics.

Alright, some more progress on the defloaters after a day of working on them: -overdeveloped all pcb's to get rid of the photosensitive layer. -cut the pcb's to size -drilled all of the holes in the pcb's -drilled the enclosures, and installing the led holders & wire ports. -soldered on, and programmed all the microcontrollers This is how it's sitting atm: Unfortunately the saw blades I bought were of terrible quality, and they weren't particularly cheap either. I could make them blunt just by looking at them, so cutting the pcb's took way longer that it should have :s. Now it's just a matter of soldering on the rest of the parts and wiring to the pcb's. Also the plugs have to be crimped on when they finally arrive.

The latter. It is about compatibility, and it can be made to work with cop, or single coil. Alternatively, I can make it switchable by repurposing the on/off switch. No worries, I'm building the defloaters in parallel, so they will all be finished at the same time.

Alright so a little update on the process. After a day of building the following has been done: -sort all parts & check for completeness. -expose, develop & etch pcb's -cut all wiring to length -mark all enclosures for drilling Here's what I ended up with (pic is a little hazy): Tomorrow I will be cutting the pcb's to size, drilling them and soldering on the electronics. Also I will be drilling holes in the enclosures. I hope to finish up the defloaters electronics wise by tomorrow evening, and maybe even get them wired as well. There's one little setback though, the guy I normally order the plugs from isn't able to deliver until 11 februari. I'm going to look if there's another viable source, but worst case scenario I wont be able to complete the defloaters until then. It's a lot of work, and there's still plenty of work left, but that's it for now. More to come tomorrow.

Single coil is what the car came with from factory, just a single coil, and a rotor + cap. Aaron (tmm9) has developed "coil on plug" functionality for m44. This way the single coil and the rotor + cap gets replaced by 5 coils directly on the spark plugs, like with the newer me7 cars. The defloater needs to measure rpm via the ignition coil, but of course the signal from a single coil setup and one of the coils from a cop setup differs by a factor of 5. I can program the defloater to accept one of the two signals, or I can repurpose the on/off switch to switch between the two.

The parts arrived today. After unpacking them I had a slight "what have I gotten myself into this time" moment. No going back now though, so it's construction time. I did have to order grey boxes in stead of black ones, as the black ones where out. Hopefully nobody minds too much. It should be hidden in the engine compartment anyway, so it shouldn't be too bad. edit: Does anyone want COP capability btw? I can make the following versions: -COP compatible only -single coil compatible only -COP & single coil compatibility switchable by repurposed on/off switch

You did, it was about the payment up front. Probably a good idea to mention that in my post :P @ wesdunn: Well that's a good question. This thing just sort of grew out of my post in this thread, so I never considered putting something there. Maybe if this all goes according to plan I will do that if that is permitted by the forum rules. For now, this is already a lot of building for me to do though, so I think I have to wait until I finish these first. Also Bob82pigdog has volunteered to act as the distribution point in the US. I'm already in the process of constructing a defloater for him atm, so I merged him into the groupbuy as well.

Alright, so a lot of the people on the list have followed through which is great! Not everybody has responded to my last PM (about the payment up front / confirmation) yet, so I decided to start ordering parts tomorrow morning (in about 9 hours from now). Just to give everybody a chance to respond. I will keep this thread updated with the build progress once the parts arrive. Also just to be sure that everyone knows: The RPM defloater only works on m43 and m44 equipped cars. It's not compatible with cars using a ME7 ECU. The N/A models with siemens phoenix systems are untested.

If everyone on the list follows through it's going to be 8 units to the US in total if I'm not mistaken.

I have sent everybody a PM about the payment up front. I'll be ordering parts coming friday, and I will start building when they get in. The aim is to finish building them at the end of the week, and having them shipped out the week after. I still need someone to volunteer distributing them in the US so I can send them all in one package. Anybody up for that?

It could trigger a beep on KRCOUNT, but it would essentially do the same thing I think. The variable pitch based on KRCOUNT idea is interesting though, I could test that out. I guess the big issue would be that these events happen very quickly, and different instances of these events may happen within a very short timeframe. All these different beeps may be quite erratic, and hard to discern, if at all audible. Ultimately I want to try to keep it simple, and easy to interpret. One can always configure one of the alarms to trigger when krcount reaches a certain number. Maybe knowing that you have a certain amount of knock, or even sum of retard values, is enough info while behind the wheel. Then it's just a matter of pulling the log off the sd-card to analyse what happened.

With the amount of defloaters I have to produce soon I'm a little hestitant to post this already, but I can't help it :) The first 'production' model of the sd-card logger is nearly finished: I think it's adorable. A lot of its functions are configurable via usb: -Startup tune on/off -Bits alarm (short beep on bits peak) -up to 6 alarms for different values of your choosing -sync the clock (it has an internal timekeeping device with a battery) I'm also installing a button which can be used to mark certain events in the logging. It still needs some testing, and some rough edge cleanup, but it's doing fine on the bench as it is. It will take some time before they will become available (need to build a pile of defloaters :P), but I'll post something when that happens.

Ok great, i have added you to the list. I've worked out the group buy price, and everybody should have a PM. If not let me know. I am going to need at least part of the money up front to buy the required parts, so hopefully that is not a problem. If at all possible, I'd like to dedicate the first week of februari to building them. The goal would be to have them all finished at the end of that week. Also, we need to work out the shipping process. It would be great if someone could act as a distributing point, so they can be sent to the US in one package. This would reduce the shipping cost a lot. Edit: I realised I sent the price in Euro, so don't forget to convert. The difference isn't very big anymore though.

Wow, great to see this much interest. In order to produce these things in a reasonable timeframe, I think it would be best if I could start building in the first week of februari. I have a week vacation then, so I should be able to build a good chunk of them. edit: it does not need a 12v feed, but it does need to be connected to the ecu side of the ign coil. In case of COP the same applies, it needs a connection to one of the coils.

There has been a lapse in defloater production due to time constraints, but I'm back at it now. The defloater list ended, as there wasn't too much interest in the end. I can reopen it of course. DScottM hasn't responded to my last pm, so I figure he is out, but maybe someone else would be able to act as a redistributing point. So people interested in the US atm would be: -DutchCanadian -boxpin -oreo931 -mojojo -gmsgltr -B850 -Wesdunns70t5m -OneWithBrick and oblark in the uk then, If I forgot anyone, or if you want in, just post below. I'll cook up a group buy price, and I'll PM everyone involved once I do.

I got the pm, and replied. Did you receive it?

I definately have to try to finish my build before those limitless motorways cease to exist 0o.

As there were more reports of the same cracking, all 5 of the pistons where cracked in much the same way, and by the nature of the cracks, I regard them as equally likely at least.Also I can't think of a reason why all 5 would crack like that, unless the rods were touching them. I'm not sure if that's even possible that high up in the piston.The location of the cracks make detonation very unlikely, as the tops of the pistons were undamaged.A weak spot giving way due to going through many heat cycles could very well have caused this to happen.Without the hardware in hand it's hard to say, but just because Wiseco is a big, well known company doesn't mean they cannot make mistakes, or produce bad batches. We may never know what happened, and I'm not pointing a finger here, but not even seriously considering a design flaw at all isn't the right mindset imo.

Why would wiseco not be at fault? Design flaws happen, so that should not be dismissed so easily imo.

Those are expensive pistons! It's unacceptable that they would fail like this imo. It almost seems like they didn't hold up against the regular heat cycles any engine goes through in its life. Crazy

There appears to be some interest in the defloater, so I thought it might be worth it to set something up. DScottM is prepared to act as a distributing point, which would drastically decrease total shipping. I can also save a bit on the shipping cost of the parts here, so I will be able to lower the price a little bit. It will take some time for me to build them though, so some patience is required If more ppl are interested, let me know.
