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!?

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
