hi guys
have been offered a free ecu from a v70r (not sure of year) will it work on an 850 t5 and will it make any difference?
if it will work i can at least eliminate the ecu from my tickover problem

i don't think it will, the V70R will be motronic 4.4 while the 850 is 4.3. Also the ecu out of a manual won't work in an auto, but will work the other way round for your info

not sure, will find out for you. its on a v70r in a breakers yard and they said that seeing as i have bought most of the car anyway i can have it if its any use to me.
will be going there later this week to get exhaust system.
