I noticed on the V35 forum that a lot of guys have changed the way the tiptronic shifts, ie pull down to go up the gears instead of push up. Which is the more natural way I believe. Also the way XR6s are configured I noticed the other day.

Has anyone done this on their S2/R34 ?

I dont think the wiring will be difficult to work out but the + and - symbols look impossible to change, any ideas apart from stickers ? Although Im the only one who drives it, apart from the odd mechanic...which would be a worry....6500revs in 2nd then goes for 3rd only to get 1st.

I've never driven a tiptronic Stagea but I drive a range of auto and semi auto trucks which all have an interlock that prevents you from selecting a totally inappropriate gear. Does the Stagea not have this feature?

I have done the reversal to the M35 and I now know that it will not select a lower gear at high rpm. I had enough time to think about what I did and select the higher gear in the new direction....

Yep, you are right, it would just keep revving in same gear until it hit limiter.

my wifes euro will change up gears if you dont change it. it will also change down if you slow to a stop (back to 1st) and if it feels like it will struggle

something i dont like, and it seems the stagea does it too!! but i dont think to the point of the honda. i was hoping the tiptronic would be smarter, but its almost like an auto that sometimes lets you choose a gear, but ultimately its in charge.

exactly the reason i'm going manual soon

The M35 box will not change up till you make it no matter what revs you give it BUT is you slow right down it will choose a lower gear when you accelerate but it does not change down as easily as when in D.

Yeah that's the C34 behaviour as well; it will just bounce off the limiter. But if you slow to a stop, it'll shift up to 1st.

I have always thought of doing this conversion; just 2 microswitches with about 4 wires to reverse. Assuming it's a purely electrical job, which I think it is. I will get around to it sometime soon, and post some pics. I'm sure someone must have already done it... the + and - signs will just take on a different meaning; ie. I think of "shifting UP" as changing from 3rd->2nd, or 2nd->1st etc. (ie. shifting the RATIO up) and downshifting as 3rd->4th etc (shifting the RATIO down)...

PS

Do anybody's S2 + and - lights illuminate at night? I replaced the two globes on the driver's side of the gearstick and now my gear indicators sort-of light up, but the + and - buttons stay dark... which seems wrong.

mine don't either. when i looked at the bulbs that were in there they were a 5w globe, and the biggest i've been able to find in the shops is 1.2w. i'm going to keep an eye out for the 5w ones and see if the + and - light up with them.

Hmm, mine dont either, gonna have a quick look now, got some time before work.

Dunno about this reversal, the standard way feels ok.

Last time i had the console out it did look as easy as swapping the dip switches.

Check your steering wheel surround see there's a flap either side, looks like

where you'd expect cruise control buttons, im thinkking of making up flappy paddles

to mount from there somehow and connect into the existing switches.

I think the theory behind the 'other way' is, in high powered cars (not mine) you are changing gears with the 'G' forces and not working against them under accel and hard braking. eg http://www.youtube.com/watch?v=JC6tTFp4W4o

Yeah the dip switches look easy to reverse, only one little circlip and locating boss.

Or could swap/transpose the wires between switches.

With the lights, only two globes on the drivers side with a diffuser that goes around

all the gear selections including the + & -, however even with two new bulbs in

the + & - still dont light up.

Need brighter bulbs or retro fit a bulb/led on the left somewhere and they should light up fine.

That sounds logical.

chook thats exactly what i think too!

the current standard setup is for dumb people (no offence to anyone who likes it that way). so its push forward to go faster and back to slow down. simple! no thought required

maybe ill 'work from home' tomorrow and do this. seems quite easy!

It is literally a 10 minute job. Just take care taking out and putting back in the center console if this is your first time. On the front of the shifter surround there is a piece that sticks down, this need to locate in a hole that keep the shift surround centered. It is very easy to break off if not careful.

Read the attached instructions on console removal, http://g35ipod.com/installHW.php?skin=1&src=mp3car-sig, part 17-20 are the relevant ones.

You have got me inspired. I just did the orange light run around hobart, only time when I use the tiptronic. Orange light run = in hobart lots of one way streets, and to get through the lights all in one go becuase of the timing you need to take many corners very quickly, accelerate and brake fast and hope to get through on an orange light, about 6 traffic lights in a row on three different roads....

I had to brake so quickly, I agree about the g-force thing, it makes sense to push the lever forward to go down a gear. You've all given me a job to do on the weekend!!!

Just locate the dark green and grey on the RHS of the selector assembly. They run from the dip switches on the LHS, around the back and into a white pin block. There is plenty of slack in the wires, so cut them at equal points at the most assessible point, swap them and join them with either crimps or solder and heatshrink.

I also found one of my bulbs was gone, replaced it, took that silly blue cover off the bulbs, still not that bright and I dont think it would ever light up the + and - unless you use some serious wattage, rather strange design from Mr nissan san.

      Are you an oil nerd?

      By Kinkstaah · Posted

      I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

      Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
