Omega General Help / Re: immobiliser bypass on 2.5td

« on: 06 February 2011, 22:17:22 »

You cannot bypass the later immobilser.

There are 4 ecus fitted to UK TDs:

U25DT have 214 and 215
X25DT have 427 and 428

You cannot interchange between  the ecus.

Both the ecu's i have are out of 95 cars with the u25dt engines and both ecu's are214's, i just dont want the hassle of programming a chip to match an ecu that cost me 20 regal king size and will only be used for an hour a year

Ha dthought about swapping the chips, as i didnt fit them (previous owner did) i wasnt too sure about what had been done to the thing because in my previous experience, any aftermarket chip fitted to a vauxhall ecu does away with the immobiliser, in saying that ive never fitted them to a diesel omega ecu, i had just thought it would have been easier to do a straight ecu swap for the 20 minutes it takes for an mot to be carried out and then stick my old one back in when it passed

Diesels don't get a high rpm test(well not at my mot station) there only tested at idle speed so this shouldn't affect the partical part of the smoke test. as longs the emissions under 3.00 your ok

Im in northern ireland mate, it wasnt a smoke test, it was the rather clown that was testing the car trying to drive it out of the brake rollers revved the plums out of it, came on boost and made smoke that james bond would have been proud of. He then got quite uppity and went straight to his computer (cos n.ireland mot testers know f**k all about cars) and refused to finish the test

The old girl failed mot on evcessive smoke from the exhaust, smoked out the mot centre while the keyboard operative tried to drive it off the brake rollers, haha. But anyway, 1995 2.5 td, has a chip key immobiliser and the ecu has been chipped, bought what i was told was a non chip ecu from a standard car just as a temporary measure to get it through the test, turns out the ecu i got was a chip key ecu and i cant get the key for the car it came out of as it has been scrapped now, d'oh! Can i bypass the immobiliser somehow, just to get through mot and then i can put go fast ecu back in, dontmind if its temporary or permanent, my car aint pretty, just need it to work. Any help greatly appreciated, cheers Gordie 

has it got IR immobilisor? cosif it has then you can change ecu without worrying about the immobilisor, I can swap mine anytime i like with no worrys, however they must be the same number, i.e 217 for 217 or 315 for 315, as an example, as for smoke, fill tank with bp ultimate diesel after changing fuel filter and filling with diesel magic, then run car up dual carriageway or motorway at high rpm(4k) in third gear for about 3 miles before the test [/quo

its got a chip in the key, probably back in the day it would have had the ir keyfob, but now it just gets the button thumped down to lock it and opened with the key. If i try to start it using the spare ecu the management light flashes constantly as soon as the ignition is turned on cos the immobiliser is on, as soon as i get it running an ecu that hasnt been chipped the smoke will go away, it smokes like fook on its own ecu cos the fuelling has been turned up so far to compensate for the amount of boost its running and the size of the turbo

its not the immobiliser causing the smoke, the cars original ecu is chipped, which makes quite a lot of black smoke when accelerated in fury, my problem is i bought a spare ecu that hadnt been opened, just so i could run it through the test as standard, but needless to say the chip in my key wont match the spare ecu, this is where my problem lies

jacked car up tonight. wheels spin in opposite directions, so will have to look out for an lsd

you'll still get that with LSD 

Not with plate type diff you wont, unless there not a plate left in it

yeah im on jon44 as gordiesideways, used to take my young fella to the diffs at bohill back in the old days, if your driving with a bit of sense about you a welded diff is no worse than an lsd, contrary to popular opinion. Most people who complain about them being dangerous are health and safety idiots who usually have never been in a rwd car never mind piloted one with a welded diff. My mum used to love my volvo 240 estate and it had a delded wiff  8-)

 And more to the point, why does your mv6 not already have a diff, was it civilian spec or an auto?

Safer method, jack both rear wheels off the ground, put rear of car on axle stands and release handbrake. With the engine off pick one of your rear wheels, it doesnt matter which one, and rotate it, whilst looking under the car at the wheel on the other side of the car. If the other wheel is turning in the Same direction you have an lsd, but if it is turning in the Opposite direction you have either and open diff or a viscous type diff. And on the subject of wheel spinning and donutting, my old mv6 quite happily diffed around a PRIVATE car park beside antrim lough, with an open diff and who flung dung remoulds, if youve got the power you will lock the diff anyway. Driving on skinheads you have less restistance between the road and the tyre, hence the reason your car would hoop so easily,because it was easier for it to spin the wheels. But at the same time, under hard braking you would have noticed the abs kicking in with less effort too because the wheels would lock easier. I'd weld the diff if it was mine, but at mot time, i find the little monkeys in their blue suits have sense of humour failure when they try to do a brake test, the look of confusion on their wee faces is priceless

Would a carlton diff not fit as a direct replacement for a 2.0 16v diff? I know from past problems that the wee 4 cylinder omegas used smaller half shafts, albeit that it was just the outer cv joints and flanges were smaller, but also they used a smaller prop shaft as well, which in itself bore a remarkable resemblance to a carlton unit, and since the rear cradle is essentially lifted straight from a carlton, it should all bolt in ok. The inner cv joints all seem to beof the same size, ie i ran 2.0 16v rear cradle, shafts and hubs, but an mv6 diff in my c20let omega for ages until i changed the rear cradle to a v6 item. The only problem i could forsee would be that if you were using carlton shafts that didnt have abs rings on them, you would have no speedo and a nice little orange light on the dash (abs obviously) to keep you company on a dark evening. I know of a couple of hooligans that fitted omega diffs to carltons, myself being one of the instigators, and from memory it involved little or no modification at all, but i never tried it vice versa. Alsoif i remember correctly the carlton lsd is a plate type diff, and they wear out if not serviced correctly, whereas the omega mv6 diff is a viscous or torque bias diff (not an lsd) which require little more than the correct grade of clean oil to functiion correctly
