how-to installing AP900 cruise control to Stagea M35?

hi there,

i bought a AP900Ci which i got cheaper from a private seller. i also ordered a 350Z T-wire to make it a plug an play kit but once reading the instructions i´m a bid confused.

what i want is, to use the OEM steering wheel buttons (allready got them used from usa). the instructions for using OEM buttons show a 3-wire and a 4-wire diagram. the problem is, that the Stagea OEM buttons does have just 2-wire.

i don´t want to use the liteon control stack. i want to use just the steering wheel buttons. any idea?

i know this thread: https://www.sau.com.au/forums/topic/384164-fs-cruise-controls-for-m35-v35-diy-install/page/6/#comments

 

and from what i read it seams to be possible to use just the steering wheel buttons for "main functions". did anyone installed the AP900 by himself or had the instructions from Commsman?

did anyone have an idea where to get speed signal from? as i don´t have a USB-data cable to reprogram my AP900Ci i would like to wire it in manually may without can-bus. only signal i wasn´t able to find is speed, as ECU don´t have speed signal wire (it gets it from CAN-BUS).

i read somewhere that the atessa ecu have a speed signal and that there should be a 4-pin plug with speed signal close to the OBD-plug.

 

if anyone have an information which helps, please let me know. big thanks!!!

did anyone know the wiring of the abs controll unit and where its located? couldn´t find anything on google.

maybe it would be an option to get the signal from one abs sensor.

 

i read that g35 does have speed signal on radio wiring, no idea if its 100% the same. will have a look tomorrow on my radio wiring.

found a pinout of the abs / ets unit, but didn´t found the location of it. even with nissan fast i wasn´t able to locate it.

but i had another idea today....

BCM should be the unit which converting the speed signal into can-bus signal, isn´t it? BCM is located in drivers side foot room where the fusebox is located. maybe i could get the speed signal from there!?

i found the japanese workshop manual for M35Stagea yesterday and translated all sites to english.

looks like i found a useable speed signal.

i have fully wired the AP900 today. will going to calibrate and test it tomorrow. if it work with this signal i write a short tutorial how to wire the cruise contoller if you don´t want to use can-bus.

the information with the non-canbus speed signal could be useful for other things, isn´t it!?

    • I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models? 
    • I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again 
    • Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!
    • curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.
    • S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
