V.e question

[smslyguy]

can you use the table b101 on the scan tool (main ve table bank 1) for adjusting your ve tables without using a wideband o2 sensor? As long as you are adjusting just the area's in stoich would you be able to use this chart? And if you can't why would they have such a chart to be able to use with your stock o2 senser's then?

You can use LTFTs and/or STFTs to tune the VE table.
You can tune the idle and non PE areas without a WBO2,
but it will be a guessing game when PE is on.

If you do use LTFTs and/or STFTs, create a calc.pid of both banks.

when you add higher number's to your v.e. table does this increase fuel or decrease fuel?

When you make B0101 VE numbers bigger, the PCM computes a bigger cylinder airmass (whenever the PCM references the VE table, see following note), which in turn (if nothing else has changed) causes the PCM to compute a bigger cylinder fuelmass.

Note:
PCM calculates cylinder airmass from these tables:
- above B0120: MAF,
- below B0120: MAF (steady state throttle/airflow) and/or VE (transient throttle/airflow),
- in SD (MAF-less): VE.
(B0120 is usually 4000 rpm).

If you just need a higher AFR at WOT, you would adjust the AFR in B3605 (OL AFR table) and B3618 (PE table).
