New motor in....wideband in too.

I've got an lm2 and the wideband is after the ypipe/cats.

Whats the best tuning method? MAF or SD.

I don't have a MPVI Pro interface.

Thanks

If you are not exceeding the limits of the MAF, it has been a proven reliable method. What year of a vehicle are you tuning?

You can't run a wideband after the cat converters.

You will never get proper readings ever. Install a bung before the converter on which ever side you choose and then you can start logging data.

You'll want to do both VE and MAF tuning. You can log the wideband through the EGR with little effort. I wired the wideband up on my 06 sierra when I owned it.
