correct

i have a new plan now anyway....

get a road angel, use that as a speedo

must be an output from the abs ecu then. i take it you switched over the transponder round the steering column?

if so, tap in a wire from the thin red/blue (left hand side one as you look at it) up to your clocks (thin red/blue on the right hand side of the plug.)

before you do the above, with the ignition on, test continuity from the red/blue from the abs ecu to the thin red/blue on the loom going into the ecu. if there is continuity then the above does not apply.

that should do the trick:thumbs:

no
this is the problem
i hava my old box which has got a sender hole, but i cant be arsed swapping it over, as i'd have to take the engine apart and it soo much effort

is there a hole in the box to accept a speedo sender?

using brosters old modified 1.4 ecu (mapped for 1.6)

so essentially, the easy option is to fit my old box? or.... get stack dials with a wheel revolution sensor?

well if that is the case, and they do take a reading from an abs sender, then that will be difficult unless you have the correct type of abs ecu. the pulse signal from an abs system is a totally different type of signal from a gearbox sender (more pulses per second) are you using the original 1.4 ecu? (remember the pulse wire goes from the relevant sender, through the mfd and then through the immobiliser pick up.

got a very simple wiring diagram of ths circuit if you need it:thumbs:

we would have used the 1.4 box but where the rear mount attaches, the thread was fucked, instead of waiting to get it retapped we fitted the 1.6 box, didnt think anything of it till robin took it for a drive

i dont know, the instructions i read to fit one said they used a gearbox driven speed sensor

VX220 dials are stack dials... Don't stack dials take a reading off of either the wheel/ABS/or drifeshaft?

thats how i did my conversion, and everything still worked fine


also, from when i was looking into the vx220/elise dials, it is possible to use the electronic type transducer in the gearbox to feed the speedo for them

no they didnt. its a myth.
astras and vectras did.


corsas either have a mechanical worm driven speedo or an electronic pulse driven speedo sender. an f15 bow could have either (depends on the year of the box). get the part number off the box and that will tell you wether its mech or elec. then go to vaux and get the relevant sender.

another thing to remember is that the electronic speedo senders also provide the vss (vehicle speed sensor) signal to the ecu. the mech sender runs a vss thats built into the clocks. if the ecu is from a car with a mech sender it may not work properly with an electronic sender and vice versa. this is because both senders omit a different type of signal. one ranges from 0-10 volts and the other 0-5 volts. (have checked both with an ocilloscope)

had this problem when i did my conversion. i tried to use an ecu from a mech driven speedo with a gearbox with an electronic speedo. it wasnt having any of it! kept dying at junctions, dodgy idle etc.... fitted new ecu from later spec car and it was fine.

u2u me if you need any further help, got a book full of stuff on this subject:thumbs:


i thought this until wednesday... i was tring to help a guy on thetigraclub:o who was getting and irratic spedo reading... i told him to change the sender in the gearbox.... he said it doesnt have one... the hole is blocked up...

i taught my local vauxhall dealer this today, but i need to know how to retro fit the sender from an ABS equipped model to mine as its expensive and i wanna be sure it works before getting the bits

i have an f15 in brosters garage, but i cant be arsed to fix it and fit it
i want to be able to fit vx220 dials too....

posted on 3rd Nov 05 at 22:05

buy my f15 box
and fit a set of mech dials


Robin

posted on 3rd Nov 05 at 21:28

my speedo is not working, which is bad.....

my gearbox has no hole for a sender, which also, is bad

what do i need to do?

dials are electric sender ones, box is F15, possible from car with ABS

i've been told i need an ABS sender, but vauxhall tell me it wont work

any ideas?
