Need help with cold hard starts and TCFI IID

Installed the dual version IID TCFI and have been tuning the base map for over 700 miles. It is starting to look good, but I'm having problems with the cold starting. When the bike is cold I have to hold the rpm up above 2000 to keep the bike from dying. If the bike is warm from a previous start I have less trouble or not at all. I have included a log of two starts. The first was with the bike cold and then I rode it for 10 miles. Stopped for two hours and repeated. I have just added +25% to tps 0, 2, and 5% between 500 and 1500. It helped a little and brought the AFR more in line, but I think that I'm fighting a different battle then what the Alpha N table can fix. I suspect that I will need to alter one of the 2d tables, (time based or engine temp) but could use a little help to narrow it down. Thanks for any/all help. Greg in seattle
