Hi guys,
last week In bought a damaged 2001 VTR1000.
it came with a smashed front end and no keys.(in Austrailia we have HISS, so this is probably going to be a major issue for me).

I plan on fitting a cbr1000 front end to the bike and converting it to a naked street bike.

I have been offered an ECU from a 1998 model but the plug looks different.
does anyone know if these ECU's are swappable if I get the matching plug for the 98 ECU? or even the complete 98 model wiring loom? both bikes have carbs, so I'm sure it shouldnt be too hard to get around. Even if there was a method of bypassing the immobilizer as my ECU should be ok to use. (just PM me if you feel its a sensitive issue to share in a public post).thanks...

the 2001 model will have some extra wires for the HISS security system, maybe thats why the 1998 has 16 wires and the 2001 has 22 wires.

the bikes nothing special (yet!) and I wont know what the engines like until I can get her started. Im not interested in even having the HISS system installed.

much appreciated if anyone can give me any advice. i dont want to pay out $600 odd dollars just to get keys cut then find the engines no good!

 

Basically, the difference is the HISS... Then there is a bit of different ignition maps, but that's rather inconsequential... However, just make your life easy, and disable the HISS, and swap the lock... It's not hard at all, but no... I won't tell you how...

 

thats good that its not hard to do, eventually ill find out how. maybe someone else will have some more helpful advice.

but maybe you could tell me if the earlier ECU difference in ignition mapping would cause any problems? I dont want to damage anything or have it running like a dog...

the ECU ive been offered is only $50 so I will go down that path if I cant find another way...

 

ok, I've forgotten about the earlier model ecu. it wont work.

I've ordered a US spec one and will attempt the mod myself. I dont want the HISS at all, as where Ill be riding theres no techs who deal with that sort of technology. they dont even have dynos, so HISS problems would be right over their heads!

I'm still after any help with the process though.
its for a Aus spec VTR with a US spec ECU (with the same connector).
I do have a rough idea but would like someones elses advice.

Even a link to the AUS/EU & US wiring diagrams would be great.
Thanks!

 

hey tweety- just noticed your location is Malmoe sweeden. My wifes sister & her husband's from there. Loved it when he came over for Christmas. heaps of beer and roast pig!
had a great time... even if he doesnt ride bikes...

 

If you are swapping in a US model ECU, there is probably a few wires left over... They should be either grounded or connected to 12V since there is no HISS signal... Which is which is best checked on a wiring diagram... I have the EU and US spec diagrams here www.tweety.se/links.php in Swedish, but links at the bottom... I haven't got any AUS spec, but I dunno if there is any difference?

Well, beer is nice... So I guess he might be from Malmoe...

 

im still a little lost with this wiring issue. I have the wiring diagrams from the manual supplied with the bike and will post them here. These should be for the Australian version, and show the 4 wires going from the immo unit to the ECU. All the wiring does seem to correspond with the schematics.



The US version ECU has arrived and Im keen to get started on it but am worried about damaging it by feeding power in where its not wanted. I'm guessing I need to find the + current going to the immo so i can find out what wires need to be grounded (?). then I guess Im lost. Wiring isnt really my forte. Im still sorting out my front end and radiator issues, but they will be an easy fix.

If anyone could PM me with any pointers I would be so thankful. I dont really wish to publish any info regarding bypassing immobilisers here, so if anyone cold just PM me ill just leave any info in that folder, not post it publically.

thanks again...

 

My advice would be to unplug the connector close to the immobilizer unit... Then, I guess the US spec ECU has the same plug? If so, plug it in and try... Nothing will break, the US ECU doesn't want the immobilizer, so with it unplugged it should fire right up... If it doesn't report back and we'll figure it out...
