I brought my car in for emmitions with a B16a swap using a PR3 ecu in a 91 teg and i was pushing double the hydrocarbons that i can run. Thsi is most likly me running rich buy why would the PR3 be dumpping htat much fuel with new plugs, air filter, and everything is STOCK as it can get. anyone? This is an unmollested ECU BTW. im not throwing any lights either.

 

hydros is usually oil/ converter mebbe a lil timing

 

great seeing hte last engine was burning oil for quite some time before theengien was swapped.
