M35 Info

Recommended Posts

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!

    • Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work 
    • You can just get the injector bosses, which allows top feeds to fit. He can use the same injectors without issue, like these (another option): https://rocketindustries.com.au/af59-2210-rb25-fuel-injector-inserts     The Racework ones look a bit better: https://www.nzefi.com/product/raceworks-lower-injector-mounting-boss-kit-for-r33-rb25det-s14-s15-sr20det/   You could also just get a similar kit like the Radium one by Plazmaman: https://plazmaman.com/product/nissan-rb25det-r33-billet-fuel-rail/?srsltid=AfmBOoogfYq49X0fu2Wdbf8yOf6zt9egyPAif_gn3Qr3G8hzAphhTgOkO70
