Hey guys,

Thought id share with you all about something that happened to me today.

So im at work and decided drive out to buy some lunch. I bought my lunch and then headed back.

So im sitting at the traffic light and when it turned green, i pressed the accelerator and basically nothing happened. The car then began to move very slowly, by this time my foot was floored on the pedal.

The car felt extremely sluggish and took like ~6seconds to reach 60km/h. I also noticed that the RPM seemed it would not exceed 2500-3000.

I immediately thought to myself that the car was in limp mode. I eventually got back to work and parked the car and turned it off, hoping that it would somehow reset the issue. I turned the car back on and decided to drive it again to see if the issue fixed itself, it didnt. I floored the car and the fastest speed i could get out of it was 80km/hour.

So i drove it back to work, and spent the rest of my afternoon all depressed and shit thinking about what the issue might be and how much to fix it etc.

Spent alot of that time researching on limp mode etc on the internet. A common fix i saw was to clean the MAF sensor.

So end of work came and i went back out to the car. Decided to try and rev it in neutral to see if it was responsive or not and if it was try and fiddle around with the MAF sensor.

I turned the ignition on and went to shift it from Park into Neutral and this was what i saw...

I turned it off and my car was magically back to normal!

Got the biggest smile on my face driving home.

Do you guys know what this mode is for? Do you think i could have damaged the engine by driving it the way i did with snow mode on?

Yes the snow button limits your revs and you can only go a certain amount of speed,

Does anyone know what models were offered these or were they a factory added option? Wish i had one or do they only come with the auto?

i know a bloke who dyno'd his R33 GTS-T sedan (auto) at a dyno day and was devastated when it only put out 63rwkw.

there was much embarassment and head scratching.

worked out later it had the snow button turned on hahah.

Mine has this. I use it in bumper to bumper traffic on the M2... probably not what its intention was for but it works well as it restricts me purposefully flooring it, which I tend to do, and reaching the car in front earlier than intended. Having said that, if I press the accelerator down 100%, it will provide full power.

I'll add a bit of interesting info to this. V35/Z33/PM35 and most of the other modern Nissan ECUs can hold up to 5 different ECU Maps. The snow function is just one of these maps, so what you are doing is in effect switching the ECU from one map to another. In UPREV, you can see what the details are for these individual maps. Example - I can see in the electronic throttle table, different values for the snow v normal mapping.

Now using the cruise control buttons it is possible to switch though these maps if you have set them up with Uprev. Failing having Cruise, you may in fact be able to set up the snow map as a valet mode, or track tune, or higher rev limit etc. I haven't tried it out, but should work.

Sounds like a cheap 'valet mode' option for those that don't have Uprev+C/C. :)

PN-Mad I've enquired about changing maps with Uprev USA and it's only possible through the Cruise Control system. If your car doesn't come with it, it can be changed via laptop only, or installing into an aftermarket cruise control system. So I don't think changing the sports/snow mode will work.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
