testing vtr ecu on a furio engine... ecu wrong size???? both single plug ecus

[mcjacko1987]

Its probably straight forward but thought I'd double check. An unlocked vtr ecu came threw the post today for my vtr conversion. Will it be safe to just unplug my furio ecu (that isn't unlocked), plug in the vtr ecu,see if it starts, unplug that and then plug my furio one back in and it will stil be ok? Just I need a few more bits before conversion so still need to use mine. This shouldn't cause problems for my ecu will it?

[saxova]

Just remove the immobilizer box before you fit the unlocked one. The original ECU will be fine, as it's got the key transponder and immobilizer box coded to it.

But just to be on the safe side.. remove the immobilizer box whilst running, that should unlock your furio ECU just to be safe.

[mcjacko1987]

how do i access that and what does it look like?is it take the steering colum surround off and its in there?is it a lil black box or something? or am i in the wrong place?

[saxova]

Its near the passenger glovebox.. under there you will find a black box (ill add a pic in a sec)

Then just unplug it, then it can't 'immobilize' your new ECU.

Here ya go bud..

so i just need to unplug that whilst mines running and itl unlock that one too? then try my vtr one in mine. then plug my 1.4 one back in. will i need to put that block back in when i put my original ecu on or will it not matter with that removed? also when i remove the immobiliser what should i expect? the car to cut itself off or carry on running? and with the vtr ecu when i try that it should start but mite sound lumpy? but as long as it starts itl be unlocked?

[saxova]

Yeah, remove that box whilst running and that will unlock your ecu.

It won't make a difference to the car running at all.

You can put it back on with your old ECU as that ecu is coded for that immobilizer box.

You can also leave it off, but that means that the car won't have a immobilizer..

Majority of people leave them off.

ok thats bang on mate. thanks :)

[mcjacko1987]

had a look. took that plate off on the dash under the glove box. cant seem to the immobiliser. is it near the fuses?

thats not it with the white plug bit is it?

[Baz]

the white thing is the diagnostic socket

[mcjacko1987]

is that white plug diagnostic reader plug or something? :S

[mcjacko1987]

the white thing is the diagnostic socket

lol you just beat me to that haha thought so

[saxova]

is that white plug diagnostic reader plug or something? :S

Yeah, thats the diag reader.

Keep looking bud, try to feel up into the dash..

Mine was just hanging there, so not sure where it exactly is from standard :y:

[mcjacko1987]

how big is this box exactly? theres a box about the size of cd case....ish. lil smaller but looks like the alarm to me. just hanging below the fuse box.seems like only wires are holding it there

[saxova]

Like the size of 20 fags.

[mcjacko1987]

cant see it lol. just took the digi cam out for betta pics. iv took pics of everything i can see from under the dash on that side, and in that fuse section. iv noticed a wire with a white plug with nothing on it, could this be where it was menna be? give me 2 secs il get them on

[mcjacko1987]

here we go. all pics iv just took:
http://i1101.photobucket.com/albums/g432/mcjacko1987/DSCF0388.jpgthis is the box i was onabout maybe the alarm, the loom underneath is the only thing keeping that up, theres about 2 plugs in the back of it
http://i1101.photobucket.com/albums/g432/mcjacko1987/DSCF0389.jpgyou can just see to the right of this pic the plug with nothing on it (you can see this is the location where the grommet is with my amp wire going threw)
http://i1101.photobucket.com/albums/g432/mcjacko1987/DSCF0390.jpgthe box again, you can see theres about 4plugs in it. also see the bonnet release catch

[saxova]

That small white plug look's like the one that goe's into the box.. It might of already been removed?

Not sure matey.

is it worth just unpluging my ecu then and try the vtr one? or will the immobiliser lock the vtr ecu then and it wont work?

[mcjacko1987]

been searching saxp none stop and it seems im probs just not looking hard enough for it. some say its took them half hour to find it. but also someone found it next to the steering column but im imagining thats a 106, could it be same for the sax?

[Lukus-vtr]

Ignore

[mcjacko1987]

haha :panic:

[mcjacko1987]

just to double check........... is this the little bugger?

[saxova]

Thats the 1!!!

[mcjacko1987]

happy days. was way up behind the fuses block. if you look at the 3rd pic down where i posted a few pics yesterday you can see the plug for it threw the smallest of gaps next to the fuse box. scanned the pics and thought that looks like it just dragged it out now haha. thanks for ya help, lets hope this vtr 1 works now :)

[mcjacko1987]

:(:(:(:(:(:(:(:(:(:(:(

[Baz]

no worky?

[saxova]

Wasn't unlocked after all??

[mcjacko1987]

http://i1101.photobucket.com/albums/g432/mcjacko1987/DSCF0397.jpg
different makes for a start :S

[mcjacko1987]

do i need a vtr loom then?

edit: was told by a couple of peeps that my furio loom will be fine for a vtr ecu

[mcjacko1987]

so im guessing this is down to not having a vtr loom? or does it mean mine is cross over or what :S

[mcjacko1987]

helllllpppppp

[saxova]

That's weird.

I thought it was either 3 plug ecu or single plug.. crossover was just a different engine-interior loom connector.

Might sound daft but you sure it's a ecu off a VTR lol? Whats it got ontop?

[mcjacko1987]

baught it off here. if you search on google images for saxo vtr ecu it comes up with the same one, mine is different. i think its probs cos mines a furio and this is for vtr. but like you i thought it was single plug or 3 plug

thats the one i got.
just looked on ebay for vtr ecu and these came up:
http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=saxo+vtr+ecu&_sacat=See-All-Categories
look the same to me :S

[mcjacko1987]

ebay again lol. searched 1.4 ecu and the result:

looks to me like i need vtr engine loom

[mcjacko1987]

Could someone show me a pic of there single plug vtr ecu please or the connection on the loom to t ecu

[Simon0014]

Weird how they are different sizes. The looms are usually fine, perhaps the ecu is from a different year and being french, consistency in manufacturing doesn't feature with them!!

Mine is admittedly 3 plug but I fitted a vtr ecu on mine. Even drove it on the 1.4 engine just had a few flat spots.

[mcjacko1987]

Mite just be the 3 plugs then that are plug n play then,with the 2 searches I did on ebay I'm really thinking I need the loom lol. The ecus I search on ebay match

[stevo1600]

bit of a bump but my vtr ecu is the same as your 1.4 ecu....

think they made 3 types of ecu.

one was the smaller type single plug,

then the longer single plug and finally the 3 plug.

am i right?

Yeah I think it is. I gave up with the long ecu in the end and just got a 3plug ecu and full loom (engine and interior) was a big job but ahh well lol

[Prickle]

Without sounding like a twat (;) :hug:) + i havent read it..

1) it would of been easier buying a car with that engine in

2) why not just get the full loom i mean like the lot? instead of bodging different bits to what not? will this ecu fit this naaa chop that single plug to a 3 plug it might work. jeez what a nightmare and setting yourself £££ back each time. Its backwards.

hurhur

hurhur
You sound a twat and should have read it :P lol
1) I had a car with engine but the head gasket went and the gearbox broke at the same time£

2) I bought a single plug ecu I though would match mine but a vtr one (but it didn't) so I bought the engine loom to match that ecu. But didn't match any sensors. So yeah I did what you have said and bought the 3plug ecu and full loom (engine and interior). Its all in now but ran into another problem which I think is a sensor.
Anyways TWAT read next time ;)

[mcjacko1987]

Hur hur :)

[jage]

is it not because ones a magnetti marelli (1.4 one) and the other a bosch motronic ecu (VTR ecu)?

I have a magnetti off a vtr and a bosch off a 106 xs both unlocked and they are indeed different :P

Both single plug btw!

Yup they where 2 different makes. I wasn't aware there was even 2 different sizes of single plug ecu as there's people I know with single plug vtr and gtis and all there ecus where same as my 1.4 was. Was told the bosh one I bought was going to be fine (wasn't told about size) then when it came to fitting, loom said no lol. Its all wired up 3plug now so here's no problem other than this sensor or air leak one lol :)
