ive seen the prices on those remapped ECUs and its rediculous. even if u have to add another board to use a chip, boards are cheap. even to "chip" a honda ECU u need a jumper, a 28 pin chip and a module to plug it into. im no expert by any means, but it seems to me that the FD owners are being bent over because we have a "rarer" high performance cars.

Boards are cheap if you're making 10,000 of them. They're not necessarily so cheap if you're only donig a few. Plus the microprocessor in the FD ECU is a bit of an odd configuration. Its a DIP but the pins are closer together. Its not THAT uncommon, but you can't go get the socket at Radio Shack.

On another note, how much will a super-afc or something similar compensate for a fuel upgrade... could a guy get away with a cold air box, DP and CB?

The chips can be reprogrammed. Getting the chip off is one thing. Pulling the code off is another.
Hopefully, I will be running a modified ECU this summer. My best friend has about 5 ECU (thanks to the forum members who sold to me) and has successfully pulled the maps off the EPROM chip. Reverse engineering is the hard part, but we have been able to solder in a socket, and run the ECU off an emulator, using the stock code
i.e. run it from a laptop. The hardest part is finding out where Mazda (thankfully the code is similar to the FC code (which has been hacked further)) but the multipliers for the injector sizes, and figure out some of the variables.
Adding boost controllers (i.e. our favorite is off the Lotus Carlton) is simple.
Cheers, and we will keep you informed

p.s. anybody with a spare M2 ECU/ Pettit ECU?

Do you guys have a website up about any of this?
I'm working on my 2nd gen ECU, but I'd be kinda interested to see what Mazda changed.

How are you reprogramming the microncontroller. The EPROM part is one thing, but keep in mind the microcontroller has on-board memory as well...that's the one that required the use of the daughter boards.
I know they're not UV-eraseable...and I'd be shocked if they had flash memory, given when they were produced.

bureau C: the eprom has been taken off the board and replaced with a socket. An emulator can be run through it, and chips can be burned easily. It appears to have most of the maps, although some data points (for various variables) are still being figured out. We have a benchtop ECU setup, and are in the process of reverse engineering some of it, but the code is not as different as expected.
Thankfully, I have 2 techs working on it pretty much full time Thank goodness for friends that are geniuses
