V5 Link - Map change
MY99 Link V5 VF22 FMIC 440cc inj and all the inlet/exhaust mods
I have decided to modify my map , which has served me well over a number of years.
Proposed additional mods fuel pump , 550 cc inj , regulator and fuel ( 98 RON +10 % toulene to achieve circa 102 RON) I don't use the car often , so modifying the fuel is no big issue.
Once all the above installed and a whip down the freeway and logging the parameters from the LINK.
Once I have the logged data at hand ,I am proposing increasing advance and reducing fuel -zone by zone until knock is detected by subsequent runs/logs -then increasing fuel back until knock free. I am leaving boost targets as is - 1.4 bar max
It will be an arduous task , but I have plenty of patience and time.
Any comments appreciated.

Yes, it's not a diesel so don't try tuning knock by adding or subtracting fuel. Tuning your ignition map correctly is the right way to do it.

So I replace OEM OS2 sensor with a wideband (Bosch or similar)- Plug into Link , run in closed loop mode and ecu will retain corrected A/R ratios.
Map is now tuned and I can revert back to open loop .
Is the WB sensor removed and the OEM sensor re installed?
Have I understood this correctly?

no but no ecu will safely do what you are asking.
its needs setting up with a laptop monitoring wideband readings and det with detcans.
It needs mapping.
