I dont think I can get more than 400km on a full tank in my M35 - I have only filled it twice since I got it, but it is chewing a hell of a lot more than my C34 stagea which was modified - My M35 is 100% stock!

Maybe I need a tune...

Just filled my tank for the first time, I never fill it but now I'm commuting :(

67.22L of 98 Vortex and the screen is telling me 545km @ 8.1KM/L.

Now I just have to control my right foot :D

The M35 should only use about 9.5-10L/100 on the highway. Anything over 10L/100km (or under 10km/L) on the highway means either something is not right or your right foot is heavy/shaky. Make sure to put the tiptronic into 5th when sitting on constant speed because otherwise the throttle is too sensitive and the torque converter will keep locking / unlocking, which will end up using more fuel. For some reason using the tiptronic makes it less sensitive and will keep the revs low and constant. :laugh:

The above is for a completely stock stagea. Depending on which performance mods you have it may do better / worse...

In my own experience, mine averaged 10.5-11L/100km on the highway when in D. Putting it in 5th using the gear lever gave me 9.8L/100km but I've seen lower than that since. I'll be doing another long interstate trip in about 5 weeks and reckon I should be able to beat 9.5L/100km this time.

WWATTTT ? 8.1 damn thats pretty high

did u just reset?

I reset a couple of days ago as I've been doing a lot of f3 driving and wanted to see how driving on the f3 was using mostly automatic mode, just slipping into manual shift for overtaking etc.

I'm hoping to be more like 10+km/L once the ECU is remapped.

Note that the M35 holds 10 more litres of fuel compared to older stageas, so 400km on a tank in a M35 is worse than 400km on a tank in a s1 or s2.

I'd say 430-500km would be a more accurate average for the M35, although it does vary quite a lot depending on where you live/drive etc.

I thought I would revive an old thread :down:

I done my regular commute from Blacktown to Tuggerah today and reset all the major efficiency and timing devices on the screen.

Here are the stats for my trip:

GAS ETA, i like it! :P

But atleast I've posted up some stats, will be interesting to see my stats after the remap in it's current configuration.

It should be putting out more power and using less fuel, can't go wrong!! :P

Once we know the remapping works and is beneficial it will be time to get a turbo to GCG for a high-flow rebuild and supply the new turbo with the dump pipe to Envy Imports for change over.

I'm excited, I've also asked Envy Imports for a quotation to supply and fit a FMIC with 3" plumbing.

The ECU should arrive from Brisbane about Tuesday, I should have paid the extra and had it sent from Japan early last week lol

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
