Thanks for response.

Currently the ECU has a narrow band O2 sensor -- when I upgraded to free flow front to back with Cowley boxes -straight through_I added the wide band AFR gauge which has been very good for the measurements.
I have a dry cell hydrogen with an Efie at 150 mV set currently for O2 and Map enhancer for adjusting the vacuum that the ECU is seeing .

I set up the Map enhancer and can lean it out, BUT I think the ECU is overriding the mods I have added due the mapping and the IAT input .

Today once it stops raining I am planning to install the IAT parallel resistor network to make the ECU think it is getting a higher temperature and so I am assuming it will lean out across the maps .

My last mod if required is to raise the CTS input then I have pretty much all mods needed .

I did have a Volo_VP15 BUT it seems to not change my ECU or anything due to my protocol - pity as it would be easier but thats how it goes with my old model 2001 Legacy GX.(My protocol is the 1941 and not the recent CAN bus).
