Stock ITR base map for a STOCK ITR (aussie 11:1 CR) with I/H/E
not sure why columns 7 and over have light up when i didnt take the car over 1600rpm, in my drive way (touched the throttle slightly)....
originally pulled codes 13 and 16 - so disabled fuel injector error and barometeric pressure sensor. codes gone, will this effect the car's driveability ?

Am i suppose to disable closed loop to get more accurate reading and is it safe running the car till warm that lean? Car smells a bit rich when i turn off however. I want to take it for a drive to make sure i pull no codes anywhere

You probably need to go after your temp compensations and your post-start trim/decay.
Columns 7-9 were probably highlighted during/just after cranking at a point where there was not much vacuum built up yet. The logger doesn't know the difference, it's just reporting whatever you tell it to. There's no other reason to be that low on the rpm scale, especially if cold.
so you arent running a wideband yet you are viewing "AFR". Am I missing something here?
Yea you are right
basically my tuner has the wideband which he puts into the exhaust tailpipe so he will read off that.
For now I am just checking the car will be safe to drive for the purpose of code checking, so none appear on the dyno.
No hard driving, just need to make sure VTEC enages etc and throws no codes.

If you don't have a cat then AFRs from the tail pipe can still be accurate.
But you have to realize all O2 sensors take time to warm up before they start reading anything other than lean. Your cold start might be normal. You can't use those numbers unless your O2 is already heated up on its own circuit. Wideband or not.
He's not looking at tailpipe as far as I can tell though, just logging straight from the ecu.
That's a good point, but wouldn't a narrowband show rich when cold since the output is inverted compared to a wideband? I guess it depends on how you have it declared in the settings.
Why so lean on a cold start?
