Ey guys just wondering if the standard ECU gets some form of speed signal.... or if there is anywhere i can tap into for a Speed signal.... need the info so i can install a AVC-R correctly..
Thanks

not to my knowledge, as speed is either cable driven into the dash, or pulse aided to the dash.
so wouldnt imagine so no.
there are kits to allow piggybacks to view speed tho.
like i'd know what tho.

speed sensors only work off the abs system

no, there are kits u can attach to driveshafts to detect rotations and provide speeds grant it u program it to ure supplied dash.

pin 19 on ecu plug

pin 19 on ecu plug
well i'll be damned. mind u i dont have an efi car to bother looking in that section of the book :confused:
hehe

carbi/efi its all good :)

yeah, well carby u cant do it. so meh. didnt think efi's could have it, but there ya go.
hows it work, manual isnt greatly into explanations.

yep PeteW's right theres a reed switch that sits in the speedo unit that sends the pulses out to the ecu and cruise and tcu
me and a few people have worked out why the ecu needs to know the speedo but we couldnt think of why it needs it

i have got Magna TP series service and repair manual so if u need to know something i can always scan and Email the pics and diagrams for you...

Here's one suggestion - on another car I've had, i noticed that if I put it into neutral with no thottle while rolling along, the idle speed stays high until the car stops and then it drops to its normal value. I assume the idle speed is nudged up when the car is moving so that there's sufficient power for power steering, vacuum for brakes etc.

I am curious as to how the speed sensor wiring is done on the Elite. Does the wiring run Sensor -> Dash -> ECU (similar to a normal Magna) or does it go to both straight from the box.

Thank for that pete, Much appriciated.
Just wondering if you could also give me the wire colour that it uses, or a diagram of where exactly pin 19 is, coz i no longer have a stardard ecu but the old loom is still in the car, so i need some help identifying which pin it is.. Thanks

looking at the back of the plug (where the loom go into the plug not the pin side) pins are numbered from top left across the plug on the top row the left to right bottom row just count along the plug, ill scan the hayes page when i get home

Skips the dash. The pulse goes straight to the ECU.

heres what i have scanned from the book

hmm thats interesting but still my magna doesnt do that lol there has to be some reason i dunno

Thats what I thought which makes wiring the Elite dash into the Elante a prick.

I know the signals sent by the pulse gen in Elite and reed switch in povo packs is the same, just was curious as to how it was done in an Elite (with respect to wiring).

Thanks very much for that pete! exactly what i needed! much appriciated indeed :D
Hope to get the AVC-R and SAFC installed next month some time.. try and get some more power :P

i put a TN digi dash into my TM SE... on your analog dash, there is a yellow/white wire... what you do is get the elite speed sensor, join the three wires to the digi dash, but then join that yellow/white wire to the green wire of the elite speed sensor... my automatic changes gears fine - so i assume it is right... other than that, putting a digi dash is easy as.

speed sensors only work off the abs system
1st gen magnas never had abs... and you need a speed sensor for the automatic at the minimum... at least the gen1 automatic need an external speed sensor anyways...

So apart from the wiring for the speed sensor I dont need to add anything, the wiring is all there? (I need to change the plugs though dont I?).

The signal for the EFI ECU should be the same as the one to the TCU :)

Did you change your fuel sender? I remember having trouble with GLX/Exec ones in my Elite years back.

Bingo. We forgot about that wire, until we pulled it down again later.

The wire is common to both. Attach the pulse, and it works both places. You'll need to change the plugs. Bank on 6-12 hours to do it, unless both are from the same generation. (I got caught out, TM donor, into TP recipient

You'll need to swap the fuel senders over. Low spec ones don't work in Elites. I didn't keep mine, as I kept short circuiting them. (Had to rebuild sedan senders into wagon senders)

:stoopid: yeah, change the sender unit to an elite one...

you need to put a wire to the dash that is fused that has constant power (normally there is a 5A fuse in exterior fusebox for it - called METER)

also, or oil sender unit change that over - cos the digidash reads out the oil pressure

nothing else i can think of really

and yes, as gav said, same wire that goes to TCU goes to ECU for speed

Thanks guys,
I knew the sensor goes to both computers (mine is manual so only ECU for me).

How big of a ***** is the dash plug - I am going to use a TM dash in a TN.

Book at least 6 hours. You shouldn't cop too many troubles with those two, colour wise.

indeed, tm and tn have very similar colours... it's a matter of joining colour for colour...

NO **** :badgrin:

NO **** :badgrin: then why'd you say that speed sensors work off abs, etc etc :P
