The remapped ECU mod (for the FD, which is what this sounds like) is really nothing like overclocking a PC. The program that the microcontroller runs was stored in two places...an external EPROM and the internal ROM on-board the chip itself. Once you've cracked the code itself, replacing the part in the EPROM is pretty obvious...you program your own EPROM with the modified code and stick it on the board in place of the other one. The other part is a bit more tricky....the daughter board basically moved the CPU off the main board, and replaced it with the CPU at its new location and an additional external EPROM. The EPROM is connected to the CPU via some address decoding logic such that whenever the address of the internal ROM is selected, it is now fooled into grabbing the data in the new EPROM.
Its a pretty straightforward thing really...you're right about that. I'm not even sure the RX-8 would need the daughter card, it all depends on whether they're using internal ROM or not. I guess the complexity really comes into play in the cracking of the code itself. This ECU does so much more that there's a lot of extra crap to wade through in order to find the parts you want to mess with. That's why I was questioning the ease of remapping the thing, but I guess we've been hearing about people working on this for a while, so once that's done, you're right...the hradware mod is much the same as for any other ECU. Hmmm....anyone have any documentation describing the architecture of the ECU???

Or how about chipping your X-Box so you can override the ROM and run a custom OS... or how about chipping PS? Sounds like it's relatively simple and pretty common...

We're working just now on a street version of the front bumper (1 pre-production piece in stock now) and the rear wing (20 in stock now).

.It is all carbon fibre made as the rear wing is.

Tell us more hfalex... Does astra provide accomodation for anyone who comes from far away?
:D

Ah... I see. A bit more complex than overclocking your CPU, but almost on par with chipping your PlayStation or X-box.
I think that this is definitely the best solution... if anyone can solve the mystery. Outside of FI applications, how can you beat the ability to access and change all the various afr maps and timing maps the 8 uses.
Any of your electrical engineer types... want to take a crack at it?

You said you have 20 rear spoilers available? how much? :D Also..I'm surprised no one has said anything about the second pic with the model in it.. not that i don't love the pic....but rules in this forum clearly state no nudes.. you can clearly see her nipples. i'd like to keep this site something i can browse on my government computers at work...thanks.

Their Italian fer crizz sakes, not as uptight as we are.
I love Italy, espesially their cars. They all have soul even the lowly Alfa has soul.
I don't know where they put it, I've taken them apart looking but never found it.
I had my 275 GTB apart down to damn near nothing and never found where it is, but it's in there. In that car by the ton.

Great information and pics , great to see that you guys are kicking some serious butt .

Oops, missed your reply....I'd love to build the daughter board (if one is needed here) that would be easy enough. Cracking the code however is the problematic part!

no seriously some techies here should pool their knowledge and start testing and tinkering and crack the ECU and then PARTY! then SCs with 350WHP and more
did I mentioned you'd be rich!

Hmm... in some other thread about the MS6, someone replied to a comment about an "easy" 300hp by getting a "chip" that it has taken until now for M6 owners to start to crack the ECU look at flashing it. I was thinking that there is a good chance that the ECU's are the same, at least at the core. Think of Ford and their ECU that is used across so many model cars and trucks. Just economy of scale. Thus the work the M6 guys are doing may hold some potential for the 8 as well... Just some random thoughts.

Are you guys coming to Spa or Zolder this year?
I'm VERY interested in re-calibrating my PCM. I'd like to know how much you know about the RX8 calibration. A bit more spark, a bit more fuel (sic Powerchips) is not what I'm interested in.

I don't understand why no one else has cracked the ecu yet. I doubt its any more complicated than cracking an xbox/PS2 or any of the other computers people have hacked over time. I could be wrong but I'd bet all of the chips are COTS parts that have datasheets available online. I'd bet a couple motivated computer engineers could have it cracked in two months and have it reprogrammed in three or four. If there's some people local to me that would want to give it a go, I'd be willing to invest some time into trying it. I'm an EE and my concentration in college was embedded systems, so I have some experience doing this kind of stuff. The only two problems are 1. I wouldn't be willing to experiment on my ecu since I know that sucker is gonna cost big if it gets fried. Maybe a junk yard has one they'll let go for cheap though. 2. I don't currently have access to a good oscilloscope or Digital logic analyzer.

what these folks do is take the chip off the board do somethign with a jumper, then change the programming with a bit of software, then put it back to gether and back into the car. Not the easiest of tasks to make widely available. now the best way would be to just be able to flash mdified maps to the PCM still in your car with no modification.
that is coming- several people are working on it. who will be first? i have a feeling we will know soon
