where do you connect the 8 lambda sensors and 2 thermocouples to FABIO headers on 575?
okay, i just could not see them from the header pics. so no error codes at all, no reprogramming of an ecu?
Interesting. Mine has this “asthmatic attack” also on start up but I have had CELissues since install. Curious if any other Fábio owners have experienced the rougher start up??
Most OB2 engines have recirculation of exhaust to speed up CAT warming which also increases cold start backpressure. With the marked improvement in flow, I would expect that on start up. My question is do you notice any resonance ?
