Running rich

Post by 8803 »

I am using a Throttle body injector that is designed for a (3) cylinder Geo on a (2) cylinder engine(1000cc vs 600cc). On my initial start up it is clear that the engine is running too rich. The software I am using is Tunerstudio. What tools do I have to lean things out and which ones do I try first?

First, be sure Required Fuel is correctly scaled for your engine and injector size.

If it's running rich when warmed up, adjust the VE table.

If it only runs rich when cold, adjust warm up enrichment.
