85 2.0 si. I had the belt one tooth off making it really advanced. It is all set TDC now and I have disconnected the vacuum advance at set timing at 15 btdc. Car runs fine but when I hook the vacuum advance up it plays with the timing again. Is there something I have to jump to keep the ecu from correcting my adjustments? And if so where is it located?
