Anyone Opened Up A M35 Computer, What Does It Look Like

[bangahh]

Anyone got money as toilet paper? or too much money ?

both US websites. you do realise there is a US M35? its not even remotely the same as an JDM M35

[bigkevracer]

True, but you can search by ECU model number there can't you? So you can check?

I didn't read anything saying it was US only models, could be lucky and get JDM too???

Or am I seeing that glass as half full again?

Im afraid the glass is empty.

just my 2c on this. I know there are a few of you that are electronically minded. who says you have to clone the chip directly? fire it up get it to spit out serial data and note that down. if if you are really intrigued and feel like memory mapping it then you can work out HOW/where it writes things to and write your own code for it.

the ONLY catch to this will be if nissan actually forgot to lock the thing. given that its nissan I would say the didn't and the hitachi's internal flash has been locked down. you will have buckleys of getting unlocked.

I know a certian russian fellow that worked with hitachi SH4s so he could probably tell you a thing or two about them - food for thought.

[scotty nm35]

Electronics, yes. Programming? Noooooo.

I would say, seeing the Nismo uses the stock chip and the aftermarket programs seem to have a p1ggybacked board, that the chip is locked.

maybe its not locked. if andys one has epoxy all over the chip, that would be to stop people reading the map they have put in there, i mistakenly remembered it as a piggyback board. so its entirely possible its not locked. id go for it NOT being locked.

Thats my opinion also; Impul wouldnt be covering it in an epoxy if it wasnt possible to read off what they'd put on it

[zei20l]

exacltly my thinking!!

[Jetwreck]

yes but in saying that ....the Impul does not have the Throttle restriction removed....it being a piggyback chip may be the reason it has not been removed!

[zei20l]

we need to see pics before we can determine if its a piggyback chip

also they may not change the throttle restriction as their ignition mapping is more aggressive, or maybe they dont want to change it due to the weak ass gearboxes we all have and they dont want to be held responsible for any damage/reliability issues.

it may not be that they CANT change it, it might be that they WONT.

I posted up pics of my Impul ECU in the 'Impul ECU' thread on M35staga.info I think? But I'm 99.9% sure it didnt have any additional chips at all.

Hey Dunc.....you do know that I still thank you every time I put my foot down for the Nismo don't you!!

Im just glad I decided to be selfish and get the Impul for me and not offer it out to someone else

yup found it! hard to say if its got a chip on top. does it have the same model number as the factory one?

ill have to dig up the factory ECU pic i took and see if its the same inside.......

I'll have higher res photos at home - but from memory I posted the details that were stamped on the chip in the thread - and they were the same as my stock one. But I will double check them

[zei20l]

nah your word is enough. so that means it can 'easily' be reprogrammed and information removed also....... like the IMPUL map

[bangahh]

Im more interested if it can be read or nissan cpu can be interfaced first.... If WRX and EVO stock ecu can be tune..... im sure nissan ones could be too

www.romraider.com

www.openecu.org

So if it can be interfaced, then thats a start.... as for me i just have had the stagea for less then 3 months so excuse me im new to what can and could be done.

[zei20l]

EVOs and WRXs have nothing common. ohh yes they do, forced induction engines.

anyway, we are looking for a company that can re-program RX8 ECUs........

He has not done any work on this ECU and does not really know anything more than us. He has specialized in other areas.
