I'm looking for some ideas on a problem with starting. About a week ago I got my ECU back and installed a gerolamy dual runner TB at the same time. My IAC steps are about 32 when doing live view (rechecked many times). Today I saw it drop to 25 in the log file though. It recovered when the bike was stopped but not shut off. TPS is at 40.

Anyway starting is getting to be a real pain, more cold starts than when warmed up. If I crack the throttle a little while cranking it fires which leads me to the IAC start adder tables. Before converting to the IID my time based table was what DTT calls the aggressive one. The ET start adder numbers before conversion were lower than now for cold temps. My converted start tables are the same as whats in the stock maps from DTT.

I've been tuning so far with the TCFI_Setup95_Gerolamy.dat and with a few applied BLM's the bike has never run better. It's just getting it started that's problematic. Before the upgrade it would start quick and idled perfectly.

I tried the start optimizing tests as outlined in the IID idle tuning tech note and the IAC falls normally and the idle is flat at 1000 rps. Still it acts like not enough air while cranking. I'm tempted to try increasing the time based start adder numbers to more like what I had before the conversion. Any thoughts?
