Here's a few from mine

VIN.......JM1FE1XXXXXXXXXXX
FCC1 FFFF FFBA

PCM Module

PCM1 FFFF FFFF 0310
PCM2 0DFF FFFF FE1A
PCM3 FFFF FFFF FF0E
etc...
In all there are13 rows of PCM Module data to enter

Then the BCE Modules...there are 16 more rows of data

The ecu is basically wiped and then overwritten with this data.....and then it works like the original.
Ok

Please help, I have 05 rx8 AT just had them reprogram the PCM but he says he can't get it to communicate with the TCM also I have no power steering. It's at the Honolulu Mazda dealership and there technicians reprogrammed a remanufactured PCM/ECU I bought and brought to them. I also bought a referbished TCM and ABS .they got the ABS to work but he supposedly can't get the TCM to communicate with the PCM. I think they won't really try because I didn't buy a brand new PCM (900.00) and TCM($740.00) from the dealership. They really don't want to help me it seems like. Do you have all the lines of code so I can show the technician and ask him if he has done all this .Please help .feel free to call me. (808)2184345 thanks.

They need to get the As Built data for your car from Mazda tech.... it is linked to your VIN
