on my r32 gtr the hicas ecu wont respond to the initialisation unless there are delays between bytes but the engine ecu responds with no delays could be to do with the extra distance to the hicas ecu in the boot or even the different processor used by hicas, my ac ecu also remains silent with no delays but i have only just discovered

the need for delays and have not tested for the aircon delays yet.

i read that plms have to send initialisation more than once sometimes they are possibly not using delays.

my hicas responds to hex ff ff e4 with 10 then i send  d1 f0 hicas then streams the error codes FF020000    ff start byte, 02 number of data bytes following,  0000 error code bytes ie no errors when ignition was last turned off

Would it be a factor of cable distance, or perhaps of the ecu relaying the information to the respective control units?

I presume that these all use the ecu consult port, right?

-->So apart from the fact that I want to intercept the G-sensors for the attesa, and intercept the BOSS sensor and directly control the solenoids for hicas, I can talk to the control units.... If only there was documentation on the 'active tests' and what they did...

cool.

there arent any active tests for hicas i dont think

you can get steering angle, direction, and a few other random things. no g-sensor i dont think

wouldnt be cable distance, electronic signals travel at speed of light. could be it needs to relay data and whatnot.

sounds good ugboot - have u tried scantech nissan (which supposedly supports the hicas/at/ac ecus) to see if they work on yours, or do they send it too fast also?

hi NewKleer

can u post the scantech nissan link if it is a demo or free

thanx

should be good enough to test it with, however it has some horrible "give us money" screen that pops up every 5 seconds :P

not sure if they disabled the hicas/at/ac sections of it or not

hi ebola

if u look at the varous wiring drawings needed to get the big picture all of the ecu's are connected in parrallel on the ddl bus this is why they respond to a different id byte ,engine hex ef, hicas e4, aircon hmm forgot that one but a4 i think, Also you can only address one at one time, they are all ecu's separately and linked by the ddl, I read that the eccu sends the rpm to the hicas ecu over the bus !

btw the attessa is not connected to the ddl so the attesa g sensors are not accessible

planning to get a pocket pc version of ecu talk out by the end of the weekend, cause if i dont do it now then it might not be till the end of the year :domokun:

hopefully will have fault codes, gauges (and maybe bar graphs)

hi newkleer

hey it would be nice ifit was programmed in java so it would run on my old palmIIIe that has j2me support and a rs232 port that plugs into the plms cable.

id fall asleep after 10 minutes if i did it in java. when you can get a second hand pocket pc for around $100, not much use trying to do it in java. a palm that old (with like 8mb ram/16mhz cpu) would struggle to run a hello world program :P

now back to work on the consult lcd

yep the palmIII is a bit pov lol, wot pocket pc have u seen for around $100 that will run your sw. :)

cheers Keith

i picked up my jornada 568 for $150 second hand. theyre on ebay but theyre a bit more than that. having only used that, i cant recommend any others - but it runs fine on mine, and probably would on something with half the specs of it

eg these might be ok:

http://cgi.ebay.com.au/HP-Hewlett-Packard-...1QQcmdZViewItem

http://cgi.ebay.com.au/hp-jornada-540-ipaq...1QQcmdZViewItem

good thing about the older pda's is they would more often come with a serial sync cable than the newer ones - so then all you need is the male-male null modem adaptor (assuming it works like my 568 does)

as more people use it on their pda's hopefully i can get some feedback on which it works well with. you probably only need about <10mb ram and i think it takes less than 1mb of rom space (more if u use logging). all that will happen on a really slow cpu is that it just wont update as often.

i should check out mine again and see how many times the gauges update themselves per second, as thats probably a good gauge of speed

Thanks newkleer. After searching through eBay, it seems the goin rate for 568's is in the range $100 to $170 with a mean around $130 nowdays. Are there any other models in the same price bracket worth looking at? I'm a PDA n00b and don't really know what would be suitable for what you have in mind.

Thanks

if i was looking for one, id check out these:

http://cgi.ebay.com.au/HP-Hewlett-Packard-...1QQcmdZViewItem

http://cgi.ebay.com.au/HP-Jornada-548-Hand...1QQcmdZViewItem

i found this site:

http://www.pocketgpsworld.com/markincar.php

appears that he's hooking up a serial gps receiver to his jornada 548 pda with null modem adaptor (http://www.expansys.com.au/product.asp?code=3011213). jornada 548 is pocket pc 2000, which actually supports .net compact framework (i thought it was only ppc 2002+). its possible there may be issues with it, i really cant say either way until someone with one says either way

its still a gamble, especially if your getting it for this sole purpose, you might be able to pick up one of those for say 60-80$.

btw, probably best to keep specific things/questions about my software in this thread: http://www.skylinesaustralia.com/forums/in...howtopic=107201 (and more general stuff here. made the seperate thread so this one didnt get inundated)

Peter the PCB works a treat, thanks again! Now, I'm having trouble with calumsult as I can't seem to configure it for two of most sensors and can't find anywhere the AFM voltage is displayed (which is the main reason I bought the kit).

Is there any other software that might be better suited please? Perhaps some 300ZX software?

And I grabbed a hp pda via eBay, cheers.

    • 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?
