Ok, update time.

The car continued to stall under hard braking in 2nd & 1st gears.

When I had the car serviced last week they said the idle was a bit low so they reset the Throttle position switch and cleaned out the butterfly.

The car now revs a bit more on start up and settles at about 850rpm (which is about 100rpm higher than it should be).

The car does not stall now under hard braking.

So problem solved.

Could the problem have been associated more so with the butterfly than the throttle switch?

As with V35's, warm idle should be at 650rpm.

I guess the main thing is that the stalling has gone, would like to pinpoint what the cause was in case others have this prob in the future.

Idle is meant to be 750 in Neutral on the M35 but as I said mine is a bit high at the moment. Would definatley like it to be lower but there is no adjustment, it is all controlled by the computer. AS it has been rest it "may" be learning again. I have only done about 200km since it was done so I will see how it is in a week. It is certainly using more fuel with this idle and wants to drive on a bit much for my liking. If it does not come down over the next week I will be going back to see if we can sort it.

What was it idling at when you were having the stalling probs?

      What brakes on R34 GTT(Europe)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
