Does anyone know if the standard M35 ECU can 'learn'?

After I changed the exhaust and dump I saw a massive increase in performance. On the dyno it looked to be 30kW and an extra 3PSI boost. Turbo starts to spool up now at around 2250rpm.

Then I fitted the pod, and on the Informeter saw I was running the injectors at 100% by about 6000rpm.

Then I fitted the HDI intercooler, and it seemed like it lost a bit, spooled up later, and was a bit more sluggish. I figured this was the lag introduced by having a bigger intercooler to fill.

Then I dumped the Valvoline oil, replaced it with Motul 300v, drove the car around 300km, and then let the car sit in the driveway for about 10 days.

Driving it on the weekend, it appears that the injectors are no longer hitting 100%, and the turbo is starting to spool at 2250. Sluggishness seems to have gone away, and it feels as good as it used to.

Would this be the ECU reacting to the mods, and relearning/retuning itself? Or would it be something else?

Not a bad result..

Ok, guys from Moscow approached me today. They have a "demo" version ready, now they need a brave person in Perth who's got a car DVD based Xanai unit (M35 Stagea or Skyline up to 2005). This gotta

The HDI coolers have F all pressure drop so you wont notice any lag in boost unless you want to log a run and find it might 50rpm later lol

ECU's are gay and literally change a tune with a change of weather.

Does anyone know if all AR-X's come with the fixtures to buy and install the grate separating the backseats from the boot ie to stop my bloody dog from jumping over. From the pictures that have been sent to me it doesn't look like my AR-X has it standard.

If yes, does anyone want to sell me one.

Just so happens to be one on Yahoo Auctions at the moment.

Here is the Import Monster link

^That's a good price. Still, $375 delivered!

Also, pretty sure that all of the mounting "hardware" is included in all models. It should be up near the child restraining points. The lower mount is along the plastic trim along the bottom of the rear windows. There's little tabs that you press in and they pop out.

I could be tempted to part with mine if you need it. I only bought it a couple of weeks ago, but Northshore put the child restraint mounts in line with where the second rod goes, and apparently can't do anything about it. Otherwise I'll just store it under the floor till I need it.

Don't you use it as a divider for the back section rather the "seat to ceiling" position?

That's where mine always is. Stops the groceries from launching everywhere.

There are multiple configurations..

Those of you running some sort of digital gauges, what do you use to do so?

Does the M35 use OBDII? Can you get an accurate boost figure from this?

Greddy infometer seems to be the most common ....and we know it works....OBDII is correct!

      OK so I just bidded $500 on an R33 GTS4 that no one seems to want. Waiting on a call from the agent to see if I won. 32 GTS4 is for sale. I can't deal with the temptation to mod it.

      Might be there for work later in the year. Wouldn't mind catching up with you fellas - can't have too many beers, but will consume copious amounts of takoyaki while executing an asian squat on the side of the road while you blokes sort out your hangovers.

      Never ending fuel pump drama

      By Duncan · Posted

      I know one example is a anecdote not data, but I'm running the same Aeroflow 525 at full voltage through a regular relay, and while I've had other fuel problems including melting the factory fuel hat, the pump itself has been fine for years. Of course, they aren't *that* expensive these days, you could swap in a new one and see if the issue is resolve. I think you had a previous thread about fuel problems, have you been monitoring and logging fuel pressure? Is there anything voltage related (for example does the voltage go up when the pressure goes down)

      Never ending fuel pump drama

      By Murray_Calavera · Posted

      So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again.
