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!

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
