Default TEn and GND jumped to relieve open loop stumbling?

This is just a thought, but while Im waiting for the time and energy to install my Megasquirt, id like to relieve the stumbling im getting under 4k without paying for an o2 clamp. I was thinking that TEn and GND jumpered would cause the ecu to only take readings from the MAF and AIT to determine how much fuel to spit out and not adjust for CLT and O2. I am also concerned about how this would affect the timing, seeing that even at idle the ecu is making adjustments (observed with a timing light). Oh an ya i also realize that it also doesnt adjust for idle, but thats of no concern to me.

Anyway, are my assumptions correct?

um you want the O2 sensor to do something or be pulling full rich relying on your maff is a recipie for disaster once you start into boost high rpm etc, just up the FP or loosen your afm a little.
