New map is then received back put on car then more data logging, checking air fuel ratio etc, then data is sent back a second time to ensure its all running as planned. Then all is finished or if further tweets required they are done.

This is what I'm looking for, especially when there is no 4 wheel drive dyno near me.
The hawkeye doesn't need a different cable. It's the same cable you use on a 2000 WRX.
The hawkeye is DBW but that doesn't affect the cable.
The 2008 onwards does need a different setup as it uses the Can bus.

So the guy flashing the ECU doesn't actually do the map adjustments !!!! and is just relaying basic information.
How is he going to log AFR as the pseudo wideband in a new age, that he will read off the OBD, only reads as low as 11.20AFR and it's not as accurate as a wideband mounted in the exhaust for mapping.

How will he check for detonation ?

How will he confirm a 4th/5th gear pull doesn't over boost, run too lean or detonate as it spools.
These things can take time to resolve and need very ballsy driving on the road.

Why are you removing the O2 sensor and which one front or rear ?
