I spoke with SAS today they said the end of the month they should be ready. They are remapping them in japan so it must be possible.

Yeah I tried contacting "MINES" in Japan for one of their VX-ROMS. . ..haven't heard from them in over 18 months of trying and e-mailing monthly. . They do one for the VQ25DET.

You can get them on the auctions.. but I would love to know how and what it is programmed for before spooning out $$$$ $1,200 to $1,500.

If only hey

The mines will work out way more than that. I did the conversion it was like $1800. Plus freight and taxes duties ect. Be careful with the ons on auction sites as a lot of them are exchange item. Found that out the hard way.

Mines, Nismo & Impul all do stand alone ECU's for vq25det.

I like the Nismo one personally, mainly due to the fact that SNOW is removed and an "economy" map is initiated when you flick the "snow" switch.... pretty cool I think... although I do believe that SAS were looking at the possibility of dual maps using a similar technique.

If you really want one of the Jap ECU's, the easiest way would be to contact RHDJapan and request that it gets listed. Part numbers and as much detail as possible make this easier AND you get a (small) discount for getting the item listed :)

VQ25DET ECU is able to remap but it is not able to real time remap tune.

Maybe a stupid question but if that is the case, how would they be able to be tuned to different car setups (for those of us who prefer not to use piggybacks)?

I either am selling my car or getting a tune and keeping it.. its costing way too much to run!!

What will a tune do for the woeful economy that they seem to get.. i need to get more than 450km's from a tank on this thing..

75L should be getting me over 600-650.

i do 50/50 highway/other.. never really am in traffic however..

A tune should get you way better economy......mines about 9.5 to 10 hwy and 13-16 around town......and you know the power numbers!

Well i drive till the light comes on.. and then drive another 50km's and then i generally get about 72-75L's in..

that usually lasts me about 450km's maybe pushing 500 if it hasnt been raining much.. (i like skidz. and 18x10 dont skid in the dry)

so if this factory tune computer option is finally coming i'd been keen as to get it. as i was going to sell it because i cant afford to run it now.. i figure the evo would be better on fuel with e85 conversion done to it.

SAS tune wont happen :(

That still seems fairly heavy on fuel; I'm not economy man either, but I'mmuch closer to 550km - 580km when leaning on it, and over 600km in girlypants mode...

I only ever get 600 when its a non stop 110 drive.. snow and back etc..

i've noticed after putting on that gtr bov perhaps economy is better.. but not 100% sure on that. tho i did install all the undertray stuff back on too.

wonder what else i can do to make the numbers better.

I find it quite amazing that M35 economy can vary so much. I've posted about this before, but I can get over 700km (~11L/100km) when driven pretty hard, but seem to get somewhat less when dawdling.

I think it's got something to do with where the engine is at it's most efficient throttle opening, ie mostly closed is less efficient than mostly open (but not WOT). Sort of why the ultra economy seekers do the burn & glide technique. So choosing the winding old road & having a bit of a go instead of using the new freeway could actually use less fuel as well as being a whole lot more fun.:rolleyes:

Now it's obvious given the right setup (Jetwreck's for example) that a good tune can turn these cars into reasonably frugal machines, for their size & weight & power output.

As to why some suffer exceptionally poor economy (other than due to issues with the common culpits like oxygen sensors etc) I've got no idea..

    • Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.
    • Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4
    • Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went? 
    • Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was £307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell. 
    • As above, you did refill the coolant and burp the system before running it again didn't you?
