And actually idle is the last thing you want to start tuning with.
meaning, dont focus so much on the idle, but the ability to get it to drive.
You need to get it up to operating temp and be able to put 20 miles on it while data logging.
Do a few short 2 miles trips and upload the log. This way we can see if you are logging the correct things.
No reason to go 20 miles wasting fuel if youre not logging the right channels.
Once your ve/MAf are getting close to 'right' then you can focus on your idle, which will make the ve/maf go nuts again and need further tuning.
It's not a fast opertion. Its a good day or two worth of dedicated work.
you can tune everything under 4k with your narrow band o2s.
WOT tuning you WILL need a wideband, or,since your lower rpm will be all tuned, find a local dyno tuner and have them polish up the WOT if that is available to you.
