Yeah, don't get me wrong. You can't "flash" these ECUs. They are too old. Flash chips were not available when these units were designed. To modify the ECU, you modify the rom file, burn it into two chips, plug them into the adapter and then plug the adapter into the ECU.

It's not hard to do, but it's not quite as easy as just hooking up a cable like the WRX guys do. In some ways it's better. The flashable ECUs can only be flashed a certain number of times and then they die and they're expensive to replace. With ours, you can replace the chips as often as you like.

(I suspect the OBD2 SVX ECU may be flashable, but I've never seen one and I don't know for sure one way or the other).
