What does the ECU control in a 1988 GL turbo engine? Detail

H

hank

I've just had to replace the ECU in a 1988 GL -- everything els
checked OK but the actual ECU, in the end, and it was that or see th
car junked since it wasn't within my reach to intervene. So I funde
the work to get the car

It's running better than it has in years, since the ECU swap -
apparently the chip did have a bad internal ground signal fault

So -- what's it doing

(I bought this from an old friend. He says the engine sounds an
drives better than it has in years -- apparently it's had this EC
problem intermittently for a long time -- He'd had it worked on by
shade-tree mechanic who didn't think the ECU mattered so had bee
ignoring it except to somehow make the light go off long enough for
California smog check station to approve the vehicle -- it did an
doe
pass smog.

I know I've spent more money on it than it's worth -- it was far awa
from me at the time, and being worked on by a reputable shop, so asid
from the (ouch!) price of a new ECU from Subaru it didn't cost al
tha
much to get it California legal

But -- now what is the ECU doing? -- I'm hoping that from here on I'l
be able to keep it running well.
