Help Ecu & Key Chip

[Bullysteeth]

Help please, does my ecu and key chip only run together, i tryed another ecu in my car today and it starts and stops straight after, is this coz of the key chip being wrong, do i need the keychip to match the ecu,and do i need the reader aswell or will mine read the new chip, thanks guys

No,you can use a different ECU no problem I don't think the keys are chipped on these's old tanks.

sounds like a immob problem, do you know if the car you got your new ecu from had an immob? or does yours?

abys were immobilised from some point around late '94 onwards.you need vagcom to do the job properly.if you post the part numbers of both ecus we can be sure

just sussed a problem the ecu was from Dan from Eastboure a member on here whos nice Red avant was trashed by a taxi, ok his car was a 95 with a chiped Key and mines a 93 without a chip, so how do i make his ecu work in mine, its homefried aswell

well,easiest way would be to send the ecu to Paul nugent(s2central) and he would put you some non immo chips in for a few quid but he seems to be awol nowadays so you may have a long wait.

note that a non immo car can't be vagcommed to work with a immo ecu(not thet I am aware of at least).I had it in my mind your car was a 1996 for some reason.

or get some non immob chips from spink?
