Does anyone know of any advantages to piggybaking a SAFC 2 to a RETEK 2.0 ecu? Im getting ready to install a retek 2.0 and someone said i should piggyback it with the safc 2?

 

With your set up (and a wideband) the usefulness of the SAFCII is to easily adjust fuel +/- during street tuning session. Then you can use the adjustments made on the SAFCII to change the Rtek maps after the session.

You then set the SAFCII back to zero. Repeat until you accomplish your goals, then sell the SAFCII.
