TOLD YA SO :smoking:

Tune on brother.. tune on.......

I myself have been too buswy to play with it in depth. But once I do I plan a lot.

Could you do me a small favor though? When he burns the new settings, have him make a backup of the BIN file to floppy ;) email it to me with a complete list of specs and changes made, and we can share it open source.. then all any scoupe owners with your mods need to do is burn the BIN with a basic eeprom burner..

Nice one Seb & Matt!......I`ll definitely go along with that!!.
Keep up the good work,

I think you'll be dissapointed. The programing done by RSR motorsports is like an intelectual property and they will not give me the bin file to distribute. At least not for the price of tuning. They on the other hand will be able to map any scoupe ECU with my program. That's kind of unfair really as I bring them the car and they make a chip with my car and can then replicate the same chip over and over again with practicaly no expenses. It's a little consilation that probably nobody would duplicate my cars setup so the program would be of little use. It would be posible to read the eprom after programing, but as I heard RSR's programs are all locked and cannot be duplicated that way.

We'll figure something out.

Arsen1k,

I *myself* have halted all "investigative projects" due to lack of time. I have been working on expanding a business, the holidays are here, and I have other projects for the scoupe that *require* my immeadiate attention.

I think we have all discussed enough detail in this thread for everone else to do they're own poking around. For example, we already have a winner that stepped up to a local VW tuner as suggested, and found that he can easily dyno tune his ECU.

Of course, anyone who explores is encouraged to come back and share. But I myself have too much on my plate right now to offer anything more at this time. I have a drivetrain that needs an entire overhaul, mods to install, and a bose waveguide component system I am custom fabricating that already has me into 3 days and a gallon of fiberglass resin SO FAR; for ONE door panel.

I have had this POS for a few months now and have hardly enjoyed it. SO I'm busy trying to take care of that first. When I get the car where I need it to be for tuning, I will crack back into it. Until then, you'll have to do your own pokin around and come back and share with the group.

Door_man,

Your right. It's not fair.

1: if they don't make you sign a EULA (electronic user liscence agreement) then when you fork over the $ and they fork over the code.. it's yours.. to do as you please with it. Plain n simple. DOn't let them BS you. Just nod your head and smile.

2: There is no way to lock it. End of story on that one. you can plug it into a burner kit, and "dump" the entire contents in a few seconds to a backup file. Don't sweat that either.

3: no, noone will duplicate your exact setup. But comparing that code to stock code could help us decipher the map varibles a LOT quicker. SO it would be very useful. But your right, we will figure something out ;) Until then, get it tuned, smile, and nod.

Peace.

- Matt

*Blows the dust of this topic*
I've spoken with Kyle Choi at Real Race and he tells me that all I have to do is take my chip out of my ECU and send him that, he'll redo it and send it back. I'll have more info on this as it has taken a long time to get a response thus far.

Anyone else with anything new on this topic???

Arsenik.........the problem with re-mapping chips with a set program of figures is that will only work with a totally stock car.

If you already have any performance mods., or intend to do any in the future, then the program will be unsuitable!.

I'm not so sure, programming the EPROM in the ECU is a simple task for some people. The boost limit for one, I'm told the ECU can handle 1.27bar or 19 psi. So why not tune that? Rev limit to 7000, and your fuel curves, all of those could help any car.

I just ordered my own EPROM programmer on ebay for 42 dollars. It programs the chip required.

Screw the SAFC

Programming would really be no problem for me. It's all the other steps involved that make it not worth it.
I've downloaded the code for a 96 accent. If you succeed or are trying to do anything later than that, its a real pain. In 97 they switched to a flatter EPROM that is a real pain to get off the board.
Also, I'm not sure at your skill level, but have you ever written an Assembly decompiler? Besides knowing the EPROM you need to know what kind of processor the code is running on, because that effects your decompilation of the binary.
If you have the time I wish you all the luck an Success. If you need or want the binary that I was able to DL shoot me an email.
Also, search this forum, a few months back I posted some great links to the entire process.
Again, Good Luck!

The S-Coupe Turbo`s ECU is programmed to go into `limp-home mode` (as anti-spike protection) if it sees boost over 12 p.s.i.............so that`s something else to program-out!.

Failing that , you could always insert a bleed-valve into the line to the ECU.

I`m not sure you can just write to the EPROM in the way you suggest.......I`ve read that Hyundai`s code is indecipherable & needs some kind of specialist to hack & break the code, in order to understand what`s already in there!.

A bit beyond me I`m afraid!!.

You never know till you try, if I cannot do the programming myself the guy at Real Race is certain he can, and has before. I should have my programmer in about a weeks time, from that point I'll be checking my fuel lines first off, then I'll move on to read and save my data from the EPROM so it may be re written.

hey

i also thought of buying a laptop and install the software. i emailed a company for the price for the software but its not cheap, it cost $298 with cable if im correct, it reads 95% of all asian cars.

this the website http://www.rennacs.com

and this is what they sended me per email

[body]Dear Pascal

Yes, the CodeReader will read codes from your Hyundai. Please find your PC system pricing below:

PC CODEREADER SYSTEM PRICING
PC CodeReader Vehicle Connection Hardware................ $298 USD
*PC EFI Petrol software module ......................................FREE!
PC Transmission software module .................................$198 USD
PC Airbag (SRS) software module .................................$198 USD
PC ABS software module .............................................$198 USD
PC EFI Diesel software module .......................................$98 USD
**Freight via New Zealand Express Air...............................$89 USD
Total.......$1079 USD
[/body]
i think you only need the first two, since we have no ABS no airbag and no diesel.


;):bye

Pascal......all that will read are the check-engine-light codes!.

The guys are talking about reading & replacing the actual programming for all the fuelling & timing curves & base-maps on the ECU`s EPROM, which is an entirely different matter!.

hey valk i know where they're talking about LoL

i thought that maybe that software could remap to, as the Hi-scan is probably capable of that. i emailed them to ask what else it could do, and maybe we get lucky!

buhbye

The Hi-Scan device can only write updates to the EPROM in the form of software upgrades supplied to the Dealerships by Hyundai.
It`s the original programming of the chip which is so hard to decipher.......nobody outside the factory seems to understand the coding used!.

I`ve read people are trying to hack it.........but nothing more ever seems to get posted!.

Stay tuned...... :devious:

Alright, I got the programmer, and I've downloaded the .bin files out of the ECU, they are 87c257 and 27c256 chip devices. One controls the Boost and one controls the Engine, if anyone wants a copy let me know, also if anyone has a ROM editor for Hyundai let me know. I'm in the process of trying another Bin file to see if it works any better, I'll know more in a few days.

I'm surprised nobody else has posted their findings.
