Dr_Drift Posted March 8, 2005 Share Posted March 8, 2005 Here's a few more maps for you guys.... I had issues getting hold of a 34 to download the bin but Ed managed to sort it out... Hope these help Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1240558 Share on other sites More sharing options...
darkhalf Posted March 10, 2005 Share Posted March 10, 2005 unfortunately i cant id the processor to find a datasheet/disassembler. i'll have a look into the addresses however when i get some time to sit down and go through it completely Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1244596 Share on other sites More sharing options...
ed Posted March 10, 2005 Author Share Posted March 10, 2005 Thanks darkhalf. If we manage to get the address table completed then I'll install the board to confirm if it works.

darkhalf Posted March 20, 2005 Share Posted March 20, 2005 there is another board NSX10AA which is a ER34 daughterboard also (not a multiboard) do you get instructions with the mutliboard on which part you modify on the ECU to get the Microcontroller (big chip) to read from the daughterboard rather than internal PROM? someone had to figure out the actual chip pinouts (and even the address table) from somewhere to make and tune these things. haven't had time to hunt through the binary properly yet....

darkhalf Posted March 21, 2005 Share Posted March 21, 2005 I'll scan and post up the installation instructions tomorrow.They are in jap though. no probs i might be able to translate some of it well looks like the badbiki mutliboard is almost finished. no more burning EPROMS since he is using NVMRAM programmed over USB. estimated about $200 but you wont need a burner/eraser. at this stage its program only... www.bikirom.com it has provision for the ER34 connector (must have copied the multiboard for the pinouts) Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1259986 Share on other sites More sharing options...

darkhalf Posted April 12, 2005 Share Posted April 12, 2005 thanks for that. i'll see how we go with the translation! sorry i haven't got around to disassembling the code yet. i'll try and get that done soon. someone has also sent me pics of other R34 ecus with a Hitachi H8/539 CPU on board. this looks similar to the R33 ecus. thinking about a daughterboard for this since badbiki isn't doing those if you could get some closeup high res pics of both sides of that daughterboard also that would be helpful to compare against the documentation. if you could email me those since those would be pretty big Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1294551 Share on other sites More sharing options...

darkhalf Posted April 12, 2005 Share Posted April 12, 2005 thanks for the offer but i've got the r33 daughterboard imaged (h8 chip) just need the er34 multiboard (previously pictured) pinouts. about a year i borrowed an r33 ecu with h8 daughterboard and took some closeups, pinouts etc. the main problem is getting the parts (84 pin connector onto the board etc). the chips on the daughterboard have had id markings removed but we should be able to come up with a new design to replace this. the hr34 h8/539 measures up 128kx8 in size. i just haven't had time to work on that since i've been doing retuning software for the emulator and maptracer im currently using the hardest thing with the multiboard is getting the correct pitch cables but badbiki has got that sussed Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1295506 Share on other sites More sharing options...
Brazen Posted April 19, 2005 Share Posted April 19, 2005 Alrighty - trying to make heads and tails of this mixed up thread - WHAT IS THE STATUS OF THIS?? Got a Neo6 Stagea and interested - but only if this thing is getting close to being sorted out.... ANY UPDATE??

darkhalf Posted April 21, 2005 Share Posted April 21, 2005 Ed is getting his daughterboard fitted soon and I have identified the main maps and some of the tables for modification. Next thing is retuning the board with an emulator (16 bit for this daughterboard) Last available version of LiveEdit for 16 bit did this but no trace... I last knew Lawrence is almost finished another version of this with calc'd maptracing in it. Sam may be able to provide more info on this I can currently do 8 bit emulation and real tracing with my Nistune software (http://home.iprimus.com.au/darkhalf/nistune/) and possibly maptrace on this ECU once I can ID TP RAM location but would need another transitronics romulator box for 16 bit (romulator in short term until I get my 16 bit emulator built) Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1310716 Share on other sites More sharing options...
Dr_Drift Posted April 21, 2005 Share Posted April 21, 2005 darkhalf - I am using this same board in an S15 next week, and have two emulators here already. Going to try and help lawrence nut out some problems, one of the issues is the grid boards high / low maps. I bought a second emulator and nissan datascan for Larence to help sort out the calculated map tracing... I'll check on progress....

Brazen Posted April 25, 2005 Share Posted April 25, 2005 Hmm I know nothing about this stuff - sounds like a few of you doing some good work to get this sorted - but the first post was like October last year!? Am keen on this duaghterboard - can someone please tell me how long until we might see a post that goes something like this: "ok EVERYTHING is sorted for the Neo6 Tiptronic/manual daughterboard group buy - just post your name if you are in, price will be approximately $xxx depending on numbers, and I'll order them on [enter date] and post them to you once I get them, along with all the info and maps you'll need for tuning to give to Hyperdrive; Dr Drift etc" That kind of post would be WONDERFUL to see soon!

ian Posted April 25, 2005 Share Posted April 25, 2005 any update? and did you still need the bin for a M-AT R34? If so, I can post mine. :-) Ian Link to comment https://www.sau.com.au/forums/topic/53011-34-daughterboards/page/3/#findComment-1317777 Share on other sites More sharing options...
ed Posted April 26, 2005 Author Share Posted April 26, 2005 Guys, we are still trying to sort things out. Can't really give you a time frame as everyone is putting in their spare time to get the fuelmap address table done. If you can't wait, you can buy the table for $300AUD if you really are in that much of a rush.

darkhalf Posted April 28, 2005 Share Posted April 28, 2005 yeah if you can post it that would help in the mentime in terms of me trying something with disassembly ... until we can get another binary out of Eds to upload to his daughterboard. the binary size needs to be 64K since 32K seems too small (like not all the code is there) dr_drift did you just upload the 64K image straight out of consult (nissandatascan or whatever program) and burn it split it even/odd into the two 27C512 EPROMs (or emulators?)
