what do i need to change-is it worth it?

[t5steve]

have been offered an uprated ecu for my 850 T5 but the numbers don't match on the ones on my ecu and it won't start car.......what do i have to change to make it work? ie what parts are coded to the ecu etc.........its an hlm ecu by the way...i know that i can get my own ecu remapped for about £150 so is it worth changing the relevant parts........ecu won't cost me anything just my old ecu and relevant parts........any ideas?

[bigrotch]

is it off another auto!!!!!!!!!!as i know autos can run a manual but manual cant run a auto

yes it is an auto...............ref light switch yes the one in dash that turns lights on/off

[T5frankie]

if its come off a car the same it should work mate

[t5steve]

have tried several ecus in my car (thanks niles and shreck ) but none will run my car....
been told i have to match bosch numbers to make it work

you need to check the numbers here LINK (http://turbo-tuner.co.uk/ttusb-compatible.htm)

many thanks pedro.............kinda more confused now my car is registered 95 but has obd port inside car as per 96 onwards.........have tried several ecus but none have worked my car so kinda suggests i have system from pre 96 ( can you follow this or am i dribbling ) as many will know i have a tickover problem with my car one of the last things that hasn't been checked/changed is the ecu (gearbox ecu has been changed) so i am keen to eliminate this as it now beginning to annoy me.........hence the question what do i need to change ( i will soon have access to a car that is being stripped but runs fine,so if it is worth the effort i will change all the relevant parts)

even tho the car is registered 1995 it could be a manufacture year 1996 (sorry even more confusing) which will explain the OBDII socket. This might help LINK (http://www.autohausaz.com/volvo-auto-parts/volvo-vehicle-identification-numbers.html)

mate mines the same registered 95 but have a obd 2 port so far i havent found a code reader to read the ecu which is a pain,but i just sent my ecu off to hlm and had remapped so i didnt really have a problem.......no help at all i know but i thought i would share that info anyway :)

Snap on Launch reads and resets codes via the obd11 plug in car. N reg 1995 -

well you never know, looking to book a little weekend away at dovercourt in january seing as i didnt go anywhere this year so i could always pop in and get it checked out,theres nothing wrong with the car but i would like it read and reset anyway!! well it it is over fuelling quite a bit but other than that...

I see if mine (snap on)can read my car just need to get an adapter socket from old boy and bring it to the meeting so we can sort your out.

many thanks for that pedro
mine is a 1996 after all...........all i need now is an ecu or the parts to convert

[bigrotch]

There's several on fleabay mateNow u know what numbers to go for etc

i got mine read by a guy at toomeys laindon who had just purchased it from snap on....don't know which one it was though
trouble is every time someone reads it it comes up with something different
and when you try to clear it it clears codes but won't clear light on dash
which is where the change of ecu comes in (recomended by niles)

[Kingsford G]

Mine is 95 and I`ve chnged my ecu no probs even though Volvo told me needs reprogramming £55 all in.

[t5steve]

the reason i am trying to find out about ecu related items is that where my son works they have a T5 that must be scrapped (sorry can't remove any parts either)
as i know one of the managers well he has said i can exchange my parts as long as i leave it running................hence i need to know what parts to exchange

have you still got the one you took out? if so could you bring it to essex meet for me to try?

Yep,its sitting in my glove box.

have already tried 3 different ecu's that "will work your car" not 1 of them would even start it let alone run the dam thing.........so you can see i am a bit wary of keep spending money on ecu's that "will work my car but DON'T
sorry for the rant but this car is fast approaching costing me more in repairs than it's worth

many thanks.........if i can find one that works i will gladly buy it........i just want one that works................
