Gday crew wonderin if by running my gtr in rwd not 4wd will do any damage to any components of the car in particular transfer cases atessa system etc?

I have air in the atessa system at the moment and am changing the clutch soon so wont bleed it till that is over, just want to check that im not doing any harm at the same time.

Cheers

Yerrrp a good thing to remember ABS will also be disabled!! not the best in this wet weather!

Your popping the wrong fuse..

Are you popping the one in the car, on the right of the steering wheel?

If you take out the one in the little kicker pannel on the right of the steering wheel, it will disable both ATTESSA and ABS

Try taking out the one from the engine bay.. I havent had any problems with ABS being disabled with that one..

In terms of conflicting stories is that you can't do the same with R33's and R34's GTR's. Thats where it gets blurry.

With R32's its fine. I have run my GTS4 for long periods of time in RWD and have heard many stories of GTR's being run in RWD aswell for long periods of time without any problem.

If you take out the fuse, you make the ATTESSA circut incomplete. If it is incomplete, it will not sence the diffrence in G forces (which is what activates the front wheel torque) and will not engauge the transfer case and hence, front drive shaft, diff and wheels.

GTS4WD is spot on. there is no need to disable ABS to disable the AWD. the reason people do is that they are lazy and just remove the fuse from the in cabin fuse panel. if you remove the AWD fuse from the engine bay all it disables is AWD. ABS is left intact. and no it won't harm your R32 GTR to do it.

Just thought i might add a mention to this..

Rmoving the fuse in the cabin removes power to the attessa/abs ecu, removing the fuse in the engine bay removes power to the attessa pump motor. This also means that you can't just come to a stop and jam the engine bay fuse in, like you can with the cabin fuse, and expect awd to come back.. Engine bay fuse requires a shutdown of the electrical system and firing it up again as you have driven the awd/abs ecu into a fault condition, it needs a reset to go again. (more pertinent to those that have switches rigged up).

Ahh, nope.

Even with a switch rigged into the fuse line in to the attessa ecu (in cab fuse one) you still have to be at a standstill for it to reset, otherwise it will fault.

Another way of faulting the atessa ecu is to turn the electrics off and then back on whilst still moving.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
