M35 Ecu Pinout

[bbenny]

I have done a search, but didnt have any luck finding what im after.

I would like the ECU pinout for an M35 stagea. I have had an SAFC II kicking around in my cupboard since owning my C34 and figured once the exhaust is done and i plop it on the dyno, I might be able to do a little fine tuning if its rich...

Cheers!

zeil, jetwreck, andy or iamhe may be able to help. I know zeil had something at one point as he was looking at hooking a piggy back up.

I'm sure if you wait one of them will pipe up and let you know

Is this what you are looking for?

I had something else floating around that I translated from the G35 manual but I cant seem to find it.

I have a pinout diagram but only in Japanese.

Let me know if that is of any use.

I have the full translated pinouts but I haven't typed them up yet. What do you need?

in the process of doing a full drawing from Scott's stuff

Dan that was exactly what I needed! thanks for that!

Looks like i have another project for the weekend!

Can you get me that info, I already have the connector and other bits modeled up in cad.

not a prob....cannot get onto it for another week or 2 as I'm flat out.

you sorted any of the low down prob's yet Dan?

No mate, Ive given up, There are too may thinks that need to be sorted out with our cars. Throttle response is my biggest problem I cant stand it once that is fixed we should see some improvements. There is no reason there shouldn't be more balls down low as its not like our cars have big laggy turbos on them. The ECU and engine control is holding things back.

[Jetwreck]

We'll get there.....there's some interesting solutions coming through which a couple of us have been working on....some of which are already available....some of which I nearly available.

I've sorted just about everything to get more torque down low....now I just need the re-flash.....hopefully that fixes everything.

We have just fitted up a Greedy Informeter to some cars and the interesting figure is the Max Throttle percentage we get. We can not get over 82% throttle!! No idea why but is obviously a major limiter.

One thought is that the ECU manages the throttle to limit the torque that get to the gearbox.

Thats interesting, Im not surprised that the ECU is doing that. I seems to me that the car's are not at all tuned for performance rather comfort and reliability (although that could be argued).

What the hold ups with a full standalone ECU and not using the standard one at all ?

To go standalone you either need to go with a Manual Valve Body on the gearbox(therefore disconnecting the gearbox ECU) or do a manual conversion. This as you no is not cheap to do. Or you can wait with the rest of us to see what the re-flash brings when it finally gets hear!

What cant we write some software to control the box using the new ECU or micro controller? worth looking into.

[scotty nm35]

The box still works with the engine ecu in limp mode, just no kick down. If someone could reflash the trans ecu also, I would be very happy.

Cable throttle helped spice up the takeoff, not as much as I expected though. It is all pointing to the cams being the culprit, the small lift cam lobe and the way the overlap is adjusted must cause the laggy low down response. The reflash should adjust this out. (if they know their shit.)

We all keep talking about the re-flash but is it going to happen ?

For me I will sit and wait as this is definitely the best option. Its a petty there is not a daughter board available. What are the lads doing in Japan ? Still driving around RB's because the can work on them

Dan I can only chase so hard....they have had it since the 8th of Dec 2009(they could have had in earlier in July but thats another story )....I have rung them nearly every week since then....numerous other people have rung them as well.

No one more than me wants this as my current tune wont let me rev past 6,000prm and with our GT30/71 you know what it must be like. In Japan they have Nismo, Mines, K-Rom, G-Zone and Impul....every now and again one comes up on IM but you have no idea of what you are getting as they all( other than the Nismo) ones need to be tuned on the car. Funny thing is I missed a Nismo one simply because I thought another would pop up some day...if only I new then what I know now.

Trust me as soon as this is available I will let you all know...Dan you also have the advantage of having the same turbo as me so you might be able to just use the same tune as me....even better if you option the rest of the system up to where I am!!!....lol

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. Had I have known they would have had to send to Korea and muck around for months I would have just sold the ECU to them and let them work it out.

For now I still hold the spare ECU incase it's needed, the unit runs fine as I have tested it in my car.

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. I would love to see how a vq25det performs in another vehicle like a datsun 1600 with a stand alone computer and none of bullshit we have.
