Does anyone know if it is possible to connect to the ecm using a laptop to control ignition timing and 4wd on a 1990 subaru ls auto?

If there is a way would someone please let me know too. Maybe my car could send me a PM telling me it needs gas or oil, perhaps show me a pop-up of a CEL code.


"you've got no oil"

"good-bye transmission"

No there's no way to control ignition timing with the stock ECM. If you have a seperate controllable ignition module, like one of the MSD units, you could do it.

You can however view you ignition timing and other various sensors by using vrg3's ECU scan tool software. You can find out more info on www.bbs.legacycentral.org in the electrical forum. There's a sticky in there about it.
