34 Daughterboards

[ed]

I can always buy the rom data and configuration file.

For around $300AUD but then I would be hard pressed to share it

[Brazen]

I dont get it... if you (or someone) are willing to buy the $300 file... cant you just run the group buy and make up your costs depending on the number of orders - as was originally stated in the first post of this whole thread??? It stated that costs to set this up would be shared by the people in the group buy on top of the cost of the daughterboard...

I'm confused.... I think I'll just stay out of it if its not that simple - to hard for my brain

[ed]

That's correct.

But if we nut it out ourselves then we won't have the additional costs.

[Brazen]

Cool - I'll leave it to you guys - but I'm happy to pay a bit more (10 people = $30 bucks more) if it means not having to wait another 6 months (been that long since this thread started) - buts thats just my opinion

Good work though - may sound like Im sh*tty but Im not - just used to group buys not taking so long to get off the ground... I'm sure it'll be worth it in the end!

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?)

Hmm, my .bin dump is also only 32K - does that mean not all of it is downloading?

[darkhalf]

on the consult side of things not 100% sure. if you cant read any ROM addresses &H8000 upwards (say in &H1000 byte steps) then i guess so but it doesn't seem right. for example on another type of HR34 from russia the H8/539 im finding is 128k big so no chance consult can't read it all without some modification to manually page the 16K memory blocks external to the MCU

this is for the ER34/WC34 only daughterboard

NSX10AA - Installation method is the solder attaching (1.78 pitch). ROM 2 uses 27C512.

Entry system is SKIP (the identical data). Being there is no odd number even number appointment, it is easy to use, is. As for connector cable solder attaching end (installation screw attachment) Priceis 5000Yen. Corresponding model ER34 (skyline) turbo car

WC 34 (the latter term) turbo car

so for this (and the multiboard also) ER34/WC34 required 2 x 27C512 (8bit x 64K) in which the image is duplicated and simulates 16bits on the databus.

being a board taking 64K in size i would think indicate requiring a 64K image out of consult? most other images have some vector addresses and blanks at the end of the image, this one doesnt.

wonder what size 'normal' data is from Grid? hopefully im wrong here and the current 32K image fits into the 64K EPROMs somehow?

i need an attempt to read the rest of the address space from consult to see if anything there just in case

[ed]

I can send you down a spare ER34 turbo manual ECU I have if that makes it easier?

Just email me your mailing address

Guys, we are still trying to sort things out.

If you can't wait, you can buy the table for $300AUD if you really are in that much of a rush.

Can you post a link to where you can buy the table? I've done a bit of a search but haven't found it..

[Dr_Drift]

I'll chip in $50 for the Address Table.... no worries.... who else?

[ian]

I'll chip in $50 for the Address Table.... no worries.... who else?

I'm in. In fact, I'm happy to organise it (If someone will tell me where they are getting that $300 quote from! :-)

Have we got 4 more people who want to put $45 in?

I'll keep a List here (by editing this post -

1) dr_drift

2) ian

3) ed

4) Gary2

5) Neo_R34

6) Coxy_

7) ?

He's a top guy to deal with, but doesn't speak very good english, e-mail is most certaily the best way to go. His grammar is quite funny so I'm certain he;s using a b-grade automatic translator lol.

Hi - I am interested and would chip in a share of the table cost - but before committing Id appreciate a recap from someone in the know of where we would be at once we get the table... this is my guess - so correct me please:

Once the table is bought and supplied to tuners who want it (eg Dr Drift; Ken @ Hyperdrive etc) we'll be READY TO GO for tiptronic and manual R34 Neo6 Skylines and Stageas - nothing else needed??

So probably something like...

1. One trusting person here buys the table - Ian or Ed? (with knowedge that at least a few of us will chip in a share of it eg $50, even if no-one else signs up) and they (or someone else) runs the group buy (makes copies of table info and all other needed tuning info etc to bundle up and post off with the daughterboards.

2. Suggestion: Restart a new Group Buy thread coz i bet a lot of R34 owners have given up on this one and havent popped back in a while - so one with a new title like "R34 Daughterboards by May 05 - ready to go so Sign Up now!"

3. Once sign-ups complete divide the total signups to share cost of table

4. Add cost of daughterboard - how much is this likely to be now by the way? - first post said $135AUD - but some posts since then talk about a new daughterboard etc

5. Take full payment and place order

6. Post them out with copies of table and all other info needed for tuning

7. Get fitted and tuned approx $500

8. Drive around with a much improved ECU set-up

If someone that knows more about this than me can either correct me or confirm we are ready to go once the table is bought - and all up I am going to be up for say around $750 (board shipped say $200 + table share costs $30->$50 + fit and tune $500) then count me in

[ed]

Ian, you can get the rom and address table from the australian agent that Sam listed.

I'll put in $50 too.

Brazen, that $135 included shipping for 1 board I'm sure shipping would be the same or a couple $ more if we get say 5 or more boards.

What I'll do is start a new group buy thread in a moment where the number of people participating chip in evenly for the rom + address table.

How does that sound?

[Dr_Drift]

Sounds good to me!

Hi Ed

I've chipped in to help (so to speak) as I suspect this project has been going around in circle for a bit too long.. :-)

Off on a tangent, the grid emulators don't look to expensive either ie

http://www.grid.co.jp/en/prod/prod257.htm :-)

Back to this project -

My understanding of this daughterboard is that it will efectively replace the on board ROM chips. However, changes to the EEPROM on board will have to be done out of circuit ie unplug them, re blow them, and then put them back in. Is this correct?

Ian

[ian]

hmmm, and the ROM swapper looks good to - http://www.grid.co.jp/en/prod/prod75.htm

[Neo_R34]

I am still interested in furthering this project, even though i have sold off most of the bits i bought to upgrade the car when this project was initiated....so guys if you need some cash or other help just let me know....

Cheers,

Michael

I notice that http://www.925style.com/editor_direct.html has gone off the air - which doesn't bother me too much IF we can get the Map specs - as I'll write my own program to modify a map.. (I'm sure you'll all want a copy.. :-)

Looking at the Grid site (ie http://www.grid.co.jp/en/index.htm) I can't find either a link to by the map specification, or a link to find the daughterboard this thread is discussing. Would you like to post them?

On another note again, couldn't we just unsolder the ROM chips on the ECU, replace them with sockets, and burn chips and put them in? Why do we need the daughterboard?

I can find where they list the binary files you can use in their software (ie http://www.grid.co.jp/prod/HP040609.txt), and interestingly, it lists for the R34 -

[ed]

Ian, the daughterboard simply let's the ECU read from the ROM that is on the daughterboard (rom board) instead of the factory rom's that are directly soldered on to the ECU.

If only things were as simple as putting on a socket

[ian]

I just went to http://www.bikirom.com/ - which where I think you said (earlier in this post) that you got the board from (not Grid as I said above). This project 1) looks to have come quite a way since this thread started, 2) is capable of real time updates, 3) is still being finished...

The early boards that started this thread aren't what is now being used, and the new boards 1) aren't available yet, 2) come with software, so we may not need to buy the MAP (his details on software are that great, so we still might need to..)
