I recently upgraded to a serial cable from my lc1 to my v2. I finally figured out how to get it to read but it seems it is reading way too lean. If I do auto ve, the numbers say I need to add like 32% more fuel. When I do the ls1 camaro that I am working on runs way too fat. When I get it to run decent the afr is like 19:1. Do I need to calibrate my lc1? What do I need to do to get the afr to read more accurately?
