IMO :) If you take something like ECUtech , I had this program loaded into an MY00 WRX and tweeked by MRT in Sydney and customtuned and upgraded by Mercury in Brisbane later when I'd added a few more mods.

When I purchased the tune as done in the first place I knew it was locked and that only ECUtech liscence owners/workshops could access the programe--I could however reset the thing at any time back to the last tune myself and clear fault codes like an AFM fault code if I had to replace one . the point being I purchased an already developed programme--so far so good.

If on the other hand I had however taken my car to be tuned with an aftermarket access motherboard fitted (for example) for a generic tune and I payed for that tuning work and the motherboard and the motherboad installation I fricked if I'm see why I should not have the access code as this would be a generic tune parculiar to that car.

In point of fact I would not have the work done at a workshop that would not provide the access code when the work was completed.-and payed for of course.

I would want it locked however--individual owners are not the only animals that fiddle with ECU's when other animals backs are turned.

I disagree with saliya that ECU tuning is anything like programming a TV remote. Coming up with every possible combination in a 20x20 matrix does not constitute IP either, just demonstrates a rudimentary understanding of permutations. That set of results is useful to nobody, a good tune is.

An ECU tune may fall under copyright laws in the sense that it is data on a storage medium - like a computer file. The right to copy (or protect against copying) is held by the creator of the work, not the physical item (ECU). Similar to owning a book, you own the physical item but you have no right of copy of the words. You do however have permission to "use" the words, similar to how you have permission to use a tune by driving the car. The book analogy isn't perfect - you don't have the right to see the raw data much as you don't have the right to see Microsoft's source code for their operating systems. You're allowed to use the end result but you're not allowed to see the nuts and bolts of how it works and potentially reproduce it yourself.

I'm with warps on this one a car enthusiast has a biassed opinion on what it should be because they only see it from their own perspective. Likewise a tuner will only see it from theirs. I see no problem with a tuner locking a tune to protect their investment of time and stop people from copying it, and I see no problem with a car enthusiast wanting access to their tune and portability between tuners. Ultimately the conditions of sale need to be discussed before the tuner starts, so that everybody understands what they're walking away with - whether locked or unlocked.

I take it you're talking about 'level of difficulty'. Plainly you've never tried programming a Blaupunkt remote :ermm:

Agreed (I don't think it's IP).

But if coming up with one of those permutations is IP; then coming up with a superset must also be.

An ECU tune may fall under copyright laws in the sense that it is data on a storage medium - like a computer file. The right to copy (or protect against copying) is held by the creator of the work, not the physical

To be copyrightable, a work must be:

* an original expression in a tangible medium (i.e. it must physically exist)

* a type of work which is copyrightable - basically, an artistic work (like a sculpture, painting, drawing, or photograph), a building (or model thereof); a video or audio recording; or a computer program.

See http://www.austlii.edu.au/au/legis/cth/consol_act/ca1968133/ for the gory details.

I don't think that an ECU tune could be classed as any of the above - so it's not copyrightable; and I believe that if it were classed as anything it would be a "computer program".

Which, as previously, the user has a legal right under the Act to view/disassemble/change for certain purposes (e.g. to correct errors, see s47E).

To summarise; a tuner may think that they have a legal basis on which they can lock a customer's ECU. I just don't think that IP or copyright laws form that legal basis.

There may well be another legal basis (e.g. EPA rules) that mandate locking an ECU - but in that situation, the new tuner should be able to unlock.

Whether or not there is a legal basis, no tuner should lock an ECU without previously advising the customer

Cheers,

just out of curiosity, if the tune is locked, does that mean you can't even look at what the settings are, or can you just not change them? so for example, if i got a tune done and it was locked, can i still look at the map settings but not change them? or can i not even look at them?

the reason i ask is that if you can still view the map then the tuner isn't doing it to stop it being copied (as you could simply make up a spreadsheet and copy over the details) but they are locking it to either stop someone (the vehicle owner) playing with it and stuffing it up, or to stop you from taking it to any other tuner. now the first of those 2 i understand, however if the second is the case and the tuner won't give the password out to the new tuner, then wouldn't that would breach the anti-competition laws?

I am presuming here but it would appear in most instances to be to prevent the vehicle being taken to anyone else to tune , in any event appearance or not the net effect of installing a lock out code and then refusing to divulge it has this result.

:ermm:

Locking probably depends on the implementation. With the Nistune case reading maps to / form the ECU becomes disabled inside the firmware of the board until the correct pin is presented whilst all other functionality remains available. Nothing is fool proof and there are specific companies set up to reverse engineer and read data just about out of anything. I dont see the locking functionality used that often to be quite honest as most tunes are paritcular to a vehicle as mentioned previously and based from factory maps to begin wtih

PIN locking was requested for copy protection (prevent copying of a collection of tuned maps which may fall under copyright) and to also stop users fiddling and then causing damage and then later blaming the tuner for it. Over the years I've seen quite a few tuners maps (remembering which takes time/money to develop) then being redistributed or sold by third parties.

Some aftermarket systems require tunes built from scratch which take a lot more time as they arent provided with initial values for particular vehicles by the manufacturer. This is a lot of time getting cold start, idle and then normal operation correct.

If the tune was to be treated like a software licence with an explicit agreement, then in this case the tuner owns the copyright behind the tune whilst the customer is granted an unlimited licence to uses it. With software agreements the licence is made to the customer to use the software but not own it

However there is no specific agreement such as this with a tuner in the typical scenario of adjusting maps to tune for optimal but safe performance on a vehicle. Copyright is debateable and locking is used in some cases as a physical rather than legal (and hardly enforceable) substitute. One would think that given the scenario before, providing indication of pin locking would be a good practice if it was to be used to avoid potential problems down the track

They feel it is their businesses intelectual property...not the customers...thats why they are locked.

i have a few shops around us that lock ECU's (holden and ford)..... because they use the same tune in each car and dont want others to see what they are doing.... its fraud flat out.

@ "Security" the dog in your display pic scare the f**king shit outa me looks like its on roids! freaken insane!

sorry to go off topic, but i agree that locking you ecu is a bit gay but can see maybe why they do it but i deffinatly think they should tell you if they are goign to and give u the option of obtaining the password by signing a waiver or somthing

just my 2 cents

I know of some tuners that won't give out the pin at a point after the tune (like the OP's current situation) as they use the same PIN on all the cars they do :)

No way I would go to a tuner that wouldn't leave it unlocked/give me the password. I'm a big boy now, if I blow it up, I blow it up.

    • I take it that you bought the centre to suit the GTR axles? As in there was a plan, not just somehow lucky that it worked? It all looks excellent, by the way.
    • New engine block time. Up to you whether you want to keep going down this road with this project. Unfortunately a lot of these cars are like this. The road to getting these cars into decent shape is long and not fun for reasons that you're discovering. 
    • Essay time. First things first, an RB running stock turbo and boost levels shouldn't get so bad as to stall from reversion if the recirc valve has been deleted. Should get a little fluffy and annoying, but in my experience, not so bad as to stall. Of course, every car is a bit different, so it remains possible that stalling will happen. So, running with no recirc valve is somewhat of an option, for otherwise stock stuff. Atmo BOVs cause all sorts of shit, even on an otherwise stock setup. Only gets worse the higher the boost and the bigger the turbo. At that point you really need to go for a different ECU and no AFM. Rebuilding the stock recirc valve configuration is not hard. You just need a stock or aftermarket BOV with the appropriate adapter for the 2 bolt flange on the back of the J pipe, and to get/make an appropriate ~1" pipe to get the air back to the turbo inlet, and to possibly modify the inlet (if it is not stock) to take the recirc pipe back in. Not hard. Just takes some cutting and welding. Putting an R35 type AFM into the car anywhere is not as simple as just buying the AFM and throwing it in. You will also need to buy the appropriate boss that will then need to be welded onto the pipe where you're installing it. You can clearly see why by looking at the photo posted above. They are not a "simple" swap for a stocker. You can't put on in place of the stock AFM. You can put one in place of the stock AFM, if you get the mounting boss and weld it to some pipe and otherwise make that pipe piece work like the stock AFM housing. Or you can buy such an adapter, either complete with the 4 bolt flange for the air box, or without, for varying degrees of work needed to then make it fit your stock airbox or some pod filter or whatever you have going on. Oh, and the R35 AFM is not plug and play. The wiring is different, but changing that is trivial. The plug is also different so you either end up repinning the original wires onto the new plug, or you just use a short adapter. If you weld a boss to the cold side pipe, the cold side pipe really wants to be 3", otherwise the scaling on the meter can get a bit weird, but whatever the pipe size, it's not as easy as just using the (fully documented in the Nistune doco) simple method for choosing R35 AFM in X" pipe size in the software, because the scaling will already be a bit different. Anyway, all of this has been comprehensively worked through on the Nistune forums, so there is full knowledge available. I would use a Link/Haltech before I would bother putting an AFM into a cold side pipe. That's a lot of effort for a bodge. Nistune is great, can work well even at fairly high power levels, but you are stuck with the limitations of it being the stock ECU, which includes needing to use an AFM, which is not always convenient for every set of modifications. You have to have a think about what you already have, what you want to have, and decide early if you'd be better off jumping ship to an aftermarket ECU. This so you don't waste time and money doing things 2 or 3 times. Never heard of ECUmaster. Sounds like a backyard operation. If there are good tuners for it where you are, and it is a solid product, then it will be fine. We're only talking about an R engine here. Back in the day they all ran on crude nasty early 90s ECUs and they were fine. You don't need a rocket surgeon's ECU to run one.
    • So left off with high hopes of having a gearbox in pretty quickly........ Got the adapter plate that week and had to chase a few threads and work out how/where everything goes as no instructions. Got the adapter fitted, test fitted gearbox and found had to cut and shave a few things. Tunnel required some hits with a decent hammer to give some clearance on passenger side but it fits with no problems,  could fit a 8hp70 with a little more work. For a cross member I wasn't going to spend $1100 on so shiny machined piece. Went through a few designs and remembered I had a gktech s chassis to cd00# cross member. Fitted that and found its close enough with a few extra bits welded so have gone that way and still a work in progress.  After this got into modifying the intercooler with some bends and clamps. I was procrastinating on this as was not keen to cut up and weld it myself but happy with the outcome.  Onto the radiator shroud and oil cooler mount. This thing took way longer than I thought it would but having to add an extra oil cooler for the trans and wanting everything within the chassis rails its good enough for now. It mounts to the chassis and gives plenty of room for lines and pipes. All the coolers are rubber mounted and sealed the shroud on the top and sides, will use some tape to seal the bottom gap of about 10mm. 20250508_111500.mp4   Next job was to build the new diff and after a delay with a friend got built this week. I ended up putting it all together with supervision and was good to learn how to set one up correctly. I ended up going a 3.69 ratio, nismo 1.5 way gt pro with gtr Axel's. Stripped it all down, gave all the parts a good clean, pressed on new bearings and set backlash. Was good working in a clean assembly room with all the gear. Once got home wire wheeled the case and hit it with some rollbar/chassis black paint. Got a few more bits done but will leave them for the next update.
    • That could be drilled, ground and welded. Would stop it progressing and leaking. But that block shouldn't be pushed very hard, as what you see there is a massive warning sign. But that fix also isn't going to happen properly with the engine in the car, and assembled. So you're looking at anew block if you're doing all that work anyway.
