M35 Ecu Pinout

[scotty nm35]

Come over and take my barge for a spin, mountains of torque, way too much for a small car. It would be a perfect transplant into an s15 size I think.

Yeah nice shot dude After paying $400+ for the spare ECU my finances had started to run dry! I couldn't afford the potential $1400+ to have the remap done.

I did offer to take it off you hands and take it over at least 2 months before I got mine rolling

Im not having a go mate, Hopefully it does happen as a remap is obviously the best option. Any idea what the hold up is?

I reckon mine revs pas 6k as it seems to hit a power band around 5.5k and hats red line at 6.75k the trouble I have is that performance is very dependant and ambient temperature, below 15 degrees its seem like it has lots more power and hits boost cut now and then. Above 15 degrees power is down.

lol....I know your not having ago Dan(although this ScottM35 dude ).

Apparently the unit is complete....it's just taking a long time to get here.

Glad to see I'm not the only one who see's what your seeing in the temp changes...I've improved it a lot with a Phenolic Runner spacer, HDI FMIC and Nismo low temp thermostat though.....just waiting on one more part which I am hoping get's here before the tune.

Yeah I was being stubborn, I really wanted to get it rolling but realistically it was not the right time. I was also wanting to see how other people were going with the piggy back systems. There seemed to be a bit of interest in the remapping but the bulk of the interest seemed to be in trying out the piggybacks first. I wanted to see what the results were there and unfortunately I now know the results were not that favourable. Hopefully SAS will come up with a stealthy tune and the remap is the way to go, as of yet however they are still not sure they can dual map (switchable) which is the option I will be attempting for once they have everything worked out and I find the results out from your remap.

When I spoke to Tom the other week he was of the believe that one of the Korean dudes had put the unit in a backpack and he was walking lol Hopefully that was a joke, if it was being sent by ship it could take 3-4 Weeks depending on customs. So hopefully it is close to arriving.

Thanks Bob, that was the diagram my tuner used to install the EMU and there are a couple of issues with it. I have had the workshop manual translated, just waiting on Craig to pull his finger out.

The emanage/haltech route was never going to end well, these units only add or subtract timing and fuel, they don't set it where you want like a remap. I was only doing that as there was really no other option. I will be driving up to SAS when the time comes, when they pull their finger out.

Im not suprised as I used the g35 diagrams and photos of the M35 harness to generate that info? Got any feedback on whats missing and incorrect and I can fix it up

Here's another G35:

I have a pinout diagram but only in Japanese.

Let me know if that is of any use.

Hi Andy my partner is Japanese so we can translate the diagram & repost for all.

Regards Cad

Cheers

Can she translate the whole workshop manual?

She could but the problem is some things dont have a direct translation so it takes time for me to work out the english for her description.Heading back to Japan in Febuary for some snow fun and intend to do some manual and parts searching.

im pretty sure thats completely different to an M35. as is a V35/V36 and a Z33.

Any updates on the re-flash side of things?

Any updates on the re-flash side of things?

This is a bit of a sore point among M35 owners.

Both Bis-e-bee & Jetwreck spent good money and a large amount of time procuring spare ECU's, and were given various assurances about the ability to re-flash their ECU's. After a huge amount of running around on their part, I believe Jetwreck's ECU has now disappeared, presumably, never to return. So he is out of pocket and no closer to the promised solution.

It CAN be done; (Nismo, G-zone, Impul and one other do it) but no-one in Australia can do it (others know more of the technical issues than I do) apparently it is quite reistant to changes.

There is no shortage of demand now, but most have given up hope of a reflash. Personally, I'm not really after much extra power, but I'd give my left nut for a linear, direct action throttle and slightly better fuel economy.

If you feel like throwing your hat into the ring go for it!

BTW wht510, I sat down & read your entire 1600 build thread the other night; Brilliant, just brilliant .

[Jetwreck]

yeh bit of a sore point......SAS in Sydney were "doing it".....but nothing ever evolved.....I started chasing on Dec 8th 2009 and still had no luck after harassing every week till August 2010(i even had a reminder set up in my calendar).

Was fed quite a few stories along the way........the last time I rang the story was that the guy who makes the readers had been taken by the army for deployment into the armed forces in Korea.....and may not get back to it until next year sometime....."apparently" it's finished and paid for just needs to be sent...... but they cannot get into his house in Korea to find and send it!

There's a couple of spare AR-X ECU's floating around at the moment so if you have another avenue and are prepared to throw some of you own money at it PM me. I'm happy with the road i'm taking atm.......just need my new motor

[zei20l]

i have a spare ECU also, RS/RX, in case there is a map difference between that an the AR-X.

direct throttle is the thing you want, anything else a piggy-back can do!

[wht510]

thanks for the feedback guys.

I'm curious about the cause of modifications to the performance and hence the ability of the factory ECU to 'keep up'.

If flashing is one of the methods of achieving stagea nirvana, then I guess I'm interested!

If and when I finally get my car delivered, i'll jump on your bandwagon and start pursuing flashing. (i mean... re-flashing the ECU)

Oh and Dale-o... Thanks for the feedback on the 'ol 1600. She's a keeper!!!

[zei20l]

is the stagea a tow car for the 1600??

i mean tow to the track not because its constantly broken lol

Nah. Drive the 1600 to the track on semis.

Stagea was bought to replace the HR31 I owned which was obviously a coupe. 1600 only has 2 seats so not very practical. Between the wagon and the 4 door 'coupe' I should have both bases covered.

I'd be keen on fitting a tow ball to the stag, but didn't really want to tow 1080kg of 1600 and 600+kg for a tandem which I don't own yet...

HR31 that RB20's awesome!

arhhhhh the memories.....great car's!

Love that video Craig, espesially the run out of turn 4. My 31 never sounded like that . If it did I'd sprobably still have it.
