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?

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.

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!

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
