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.

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!

    • Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/
    • Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)
    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
    • My thing I'd be doing, is pulling it out, and just getting the tune cleaned up for now. Before that even happens, checking over everything, like vac hoses, fuel hoses, etc. No point dropping thousands on sensors if the moment you start it back up all the oil leaks out, or it has massive vacuum leaks etc.   But really, to know what to do, depends on what your use case is. Hard core track car? Throw most sensors available at it. Street car, I'd probably just run oil pressure, oil temps, water pressure, water temp, probably fuel pressure too. I don't know exactly what the Link can handle and do with those though. And if it's mainly just to cruise the streets, rather than mountain runs, you can probably skip most of the above if you've already got them in as gauges and warning lights.   PS, inb4 "sell it and buy a modern sportscar"
