Found the answer to the above questions

I found this pic of a 91-93 ecu for a V8 soarer, Does anyone know if the 94 soarer is any different?

The 96 is quite different.

What I do know now is, BE CAREFUL.

I was reading the problems with your ECU and I dont plan to do this myself, Ill take out the ECU and give it to someone that knows what they are doing

I changed the caps in the ecu over the weekend but seems like my fuel consumption has become worse. Doing about 5L per km.

Any ideas if I've done anything wrong or missed something?

For the record the 94 soarer
ecu has 8 caps
2 10uf
2 15uf
2 100uf
1 47uf
1 220uf

Any info would be appreciated

possible problems are:
1)did you ensure you put the new ones in with the correct polarity?

electros will not function if the polarity is reversed.

(caps are marked + and -)

2) did you use the correct tools/method for removal/replacement.

Too much heat will damage the tracks.

Tom, I looked at Jack's ECU. There was solder across 2 tracks that shouldnt have been there form his attempt. This has subsequently damaged other components. I did repair (remove) this and checked everything else (and replaced remaining caps), however it seems the damage was already done.

hi christian.

people do not realise that working on SMD pcb's that are 20yrs old is a job for "qualified" people with the correct tools.

keep up the good work you do.

hey Tom, thanks for your comments but i probably jumped the gun posting up about my ecu caps change has effected my fuel consumption, now thats its been few days i notice the difference in the car being smoother and fuel being better

Just wondering if the polarity was incorrect or used to much heat would the ecu have worked at all?
