Ok first off yes I have checked dsmecu yahoo group. I am using tuner pro rt with the eb23c xdf and bin files from ceddy.us. it has been a wonderful addition to the car and I am very great full that it was made available to get the car at where it is at now. problem is that I am wanting to add stutter box to the code. I have read it is like 1g code with the exception that it uses a double acumulator and the 1g code uses x. can anyone explain this to me? I have found the rev limiter code in the bin and understand somewhat how the code works, but I do not fully comprehend the ins and outs of editing. I have tried different test to the stock rev limiter code with no success. all I can manage is the car to start then die I have asked on dsm ecu. but no one has responded. I'm not asking for the code I want to know how to mod the code for future reference if anyone knows anything help would be greatly appreciated please no responses about swapping to link. I do not want link need link or care about link at all. this is for my personal reason of wanting to know more about how the dsm ecu works and what all I can make it do purely a learning experience to me

Is anyone still doing editing?

^ Disassembly, probably come in handy for you.

I'm not exactly sure on all the opcodes for the processor, but skimming through the diss it looked similar to the 68hc11 so you can check this list.

And some helpful descriptions to the actual opcode meanings, http://sonic.net/~mikebr/efi/stuff/opcodes.html

Are you trying to add a studderbox / alternate rev limiter to the stock 2g code ??

Yes. I was trying to add stutter to the eb23c binary code. I figured it out today. Working now and modded the xdf for the stutter box as well. Works like a champ. Code was correct I wrote but did not use the x compare op for the Tcas values so everytime I loaded the vss in the new code it was wiping out the tcas values

Ty for the links. Added them to the desktop. Currently have a copy of the 68hc11 op codes as well

You're welcome, glad to help. Happy to see someone else doing their own thing.

Well update. I successfully added stutter box to the stock eb23c image of the 2g eprom chip. Now to work on nlts and anti lag features

Awesome.


Now start work on speed density.

I will eventually work to sd.

Im.looking for some xdfs , i have ones you sent but sttuter and revlimiters got some problems they dont apply as requested

hi! i was taking out my chip (socketed eeprom) and the chip losse a pin... i would like to copy into a new one... does anyone have the address (start address and & end address) for a 27C512R
