yes, I can't see any issues with a straight Bose-Bose swap. Just make sure you get one from the same series as the face plate needs to be swapped too. If you have navi,, it would be easier if you get a HU from a G35 with navi. If you have a FM band expander installed for the radio, you will need to remove that too when fitting a G35 HU

Cool thx ...don't have navi and i can live without a DVD. Perfect option :) just hope I don't end up buying a dud

Does that mean you don't need an expander with a US unit?

I noticed with my unit that the output boosts when I adjust the bass and treble.. or up the volume to 20 and turn it back down ... weird pinch.gif

Great info! So I'm guessing that V35 Bose to G35 Bose would just be a straight swap?

yes BUT the reverse is not that easy.. if you have navi then it is not. they are different.

sonic,

is it a PDF?

Chris - Yes, it is a PDF

Poke - that is correct, you must remove the band expander when fitting the US unit, they use the same radio frequency range as we do. If you leave it installed, you won't be able to receive most of the radio stations.

The G35 units also have speed sensitive volume, but that doesn't seem to work on mine, I am guessing the V35 doesn't have the speed signal wire connected from the speedo cluster to the HU, if I have enough time on my hands, I might see if I can connect it. (any advise Chris?)

firmware is different on the JDM one and there is no wire there for it for the USDM one to work. there is a speed wire in the car that I use for cruise but I'm not sure if it is stable enough to run that.

yeah, I thought that might be the case. I was going to check the pin on the back of the Speedo cluster too see if there is a speed output that complies with what the g35 FSM shows. If it does, I will try adding the wire for the HU.

If you can't find a speed signal wire there, I think the one Chris is talking about is on pin 27 of the TCM (Transmission Control Module) which is behind the passenger side kick panel. It's a yellow black wire. At 20km/h it frequency is 185Hz (according toG35 manual). Is that in the range you require?

According to the G35 FSM, the speed signal for the stereo should be approx 55hz at 40km/h

Mmmm, that may not work then. Hunting around in the back of the dash could be your only hope, but it's hadly life or death though hey :rolleyes: .

      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

      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.
