if you have the hydra-specfic autotune/wideband deal, you're ready to go.
dial in your AFRs
warm the car up
open the software and upload from ECU to PC
in settings, turn on autotune
set the autotune rate for a street-friendly 16-20 in all rpm ranges,
save and download (restart the car) and go drive. avoid triggering enrichments if you can, but it shouldn't make too much difference.
if you can, do a couple full rpm sweeps at various loads
then park (LEAVE THE CAR RUNNING!), upload the map from the ECU to the PC
go into settings and turn off autotune.
save the map (I save in the format YYYYMMDD_001_description)
then download it from the PC to the ECU
note that you HAVE TO pull the map off the ECU before shutting off the car to get the autotune changes. they are volatile and NOT reflected in the software prior to the upload from the ECU. which is why you wanna leave the car running when you upload to PC
all that said, the ECU is pretty good at autotuning. though I'd be careful at high boost, up to 10 psi is not a big deal if you've already got a decent map as a baseline.
