[bristol s4]

anyone else had problems remapping s4, just took it 2 forge motorsport and laptop could get no response from ecu so was unable to remap it, anybody know why this might be as they have never come across it before ? cheers, justin

what model yr is it?

 

[John@ECM-TECH]

bet you it's a NDW model with the read only ecu, on those you neeed to completly replace theh ecu with a freshly burned one

I've got an October 98 S4, so one of the first ones made. MRC mapped mine without having to replace the ECU.

On the earlier ones its a replacement chip job on the ECU, the DBW models with the later ME7 ecu can be flashed

cheers guys 4 the response and info, is it worth me trying somewhere else or do i need new ecu ? s4 is a 98 if that makes any difference ?

 

[bristol s4]

Chip n spin on this forum could do the chip swap for around £250 ish

You do not need to replace the chip in an S4!!!

All S4's are DBW, and all can be mapped via the OBDII port.

[bristol s4]

98 S4 will need the chip replaced or at least done on the bench in boot mode. Not possible to do over OBD. This is true for most VAg ECU's upto September 1999. There are of course some exceptions to the rule.

Thanks.

definitely interested in getting chip done, where about u based 2 ?

My ECU was removed from the car the first time to 'unlock' it, but i've since had 3 remaps done via the OBD.

I wish mine could be done like that, i am on my 3rd chip already, really need a socket i think
