I agree. A wideband oxygen sensor is a must! I love mine, it makes me feel a lot better about running high rpms with full boost. I'm using the PLX Devices R500 which lets me monitor EGT, AFR, Knock, RPM, etc...Plus it is capable of datalogging with or without a laptop plugged in.
I think AzzKickr is looking for something to use so he can use a BOV to atmosphere. I'm not sure if the split second piggyback can do that. It would be nice to use something that completely eliminated the MAF sensor and replaces it with a MAP sensor. __________________
