Re-educating ECU

[pezzler]

I'm in the process of eliminating possibly causes of my recent idle/fuelling issues. I have removed the FCD, TSD, and boost controller. The car ran like sh!t after fitting these

 

I have a few/lot of quick questions about the ECU

 

When the ECU has been reset, how should I expect it to run at idle, and under load?

 

Will it be a case of it running a little rich, then a little lean?

 

My car is an auto, will it hesitate and splutter a little during auto gear changes?

 

On a "cold start", will it initially idle really low(900 rpm) rather than the usual 1800(ish)?

 

Last one (), when I initially start my car after having the battery disconnected; it idles smoothly at about 900rpm from a cold start. If I switch the ignition off, then back on it will pulse between 1800(ish) and 2200(ish). Has anyone had this following a reset?

 

Sorry about all the questions, just want to make sure its going to do no harm by driving it
