there is also a 'start enrichment' that occurs regardles of coolant temp, perhaps thats it. theres some decent info in the autoshop101 docs on all of this, ut im at hospi at the moment.
ALSO: i just realised... what i posted above, doesnt necessarily refer to the CSI. i could just be a correction adjustment of the duty cycle of the regular injector cycle. come to think of it, there was no mention of the CSI specifically at all...
