I've got a LC-1 wideband, a dataQ peripheral thingy, and a tweecer R/T. How do you hook them all together so that I can datalog AFR through the Tweecer?
You dont have to have the dataQ, you can tap into your EGR and have it sync up that way as well.
You would have to cut the EGR and run the o2 sensor wires to that of the eec and log the EGR with the tweecer. If you want to keep the EGR (not delete it or want to keep it when your not tuning) you can run a switch to the EGR/wb and switch between the two.
