Re: FS: ECM USB Comms, vs pcm into vn with usb laptop

Postby 4x4sandman » Mon Sep 21, 2015 2:10 pm

Hello,

I have bought a 2nd hand unused vs bt1 808 with the pcmhacking 128k navram installed in it. It was originally intended for a vs but I want to put it in my VG 5 ltr. I got the 16 pin aldl plug to usb cable with it but, as I just learnt, the vn/vp/vg/vq doesn't have the 16 pin aldl plug. So, how can I plug this into my, usb only, laptop?

Thanks in advance, Laurie.

Wire in an aldl plug. Provided your ecu has high speed comms. If it's an vn 808 ecu it would of needed a sxr chip installed. Or hopefully it's a vr type 082 ecu. Post a pic of the circuit board and we can tell you your next plan.
By having the nvram doesn't guarantee high speed comms but hopefully it's a good sign.

Have a look on here there's info on wiring the 16 pin port. And lots more on Google.

[url][/url]Hi Dylan, fast reply, thanks. Ive been searching on this for a few hours now. I was just comparing wiring diagrams between the vn and vs to do something similar then I saw your reply. The vs aldl plug uses 3 wires and one seems to be the right color in the right spot, (A9 WB) but that's as far as i'd got.

So, is it as simple as connecting to a8 to 9, a9 to 6 and d10 to 5? I used this diagram http://pcmhacking.net/forums/viewtopic.php?f=32&t=1352#p14535 to work this out. For anyone wondering the numbers refer to locations on the pcm's plugs then the aldl plug.

according to the post you just linked its aldl plug pin 9 -> pcm plug C11 and then the other two you need are just +12v and GND.

I apologize, I didnt say I was looking at the vs manual diagram in the comment below the main post in that link, thanks for making me aware of that 202. I'm pretty sure my new pcm is for an auto. Sorry for not having everything in order guys. So, if my pcm is for an auto, C11 is the one with the data, if its manual, its a9?

Yes, that PCM is for an auto. the problem is, the Auto and Manual pinouts are significantly different. the VS manual pinout is identical to the VN, but the auto is different. do you have the loom to go with this pcm?

Ok, so I can see two options, 1; take the nvram out and plug it into where the memcal goes in the vg's original computer, it looks like the same plug there, or 2; re-pin the harnes plug to suit the later model computer.. option one seems too easy so im hesitant already!
