fixed shitty link
Here is the data log of the cam break in.
Someone correct me if I am wrong on this
VE = base fuel map
AE = Part throttle acceleration MAP/Modifiers
PE = WOT fuel MAP/Modifiers
Datalog looks very rich and your IAC counts looks weird starts high in the beginning and at the end it settles down to zero??? If you can get it to idle decently, consider doing this: http://www.gearhead-efi.com/Fuel-Inj...-Fuel-Pressure
The issue with the IAC is what I am trying to fix, not sure what is going on with it. I changed the VE1 corrected table and got it to idle and start better but now it dies when i put it in gear.
added some fuel to get it to run in gear, took it to the gas station to fill it back up and noticed it was way rich at cruising rpm to and from the station. Multiplied the 1200+ rpm blocks on the map by .75 to reduce the amount of fuel in it and quick burn and drove it home, BLMs were in the 135 range, o2 voltage bounced between .350 and .550 on the trip home last Sat. It has set without being touched since its single digits here, I decided to put a battery tender on it while it sits and I decided to start it. Turned over a few times then fired right up without an issue, I must not be messing it up to bad. Headed on vacation for a week will be back tuning it once I get back, hopefully warmer also.

A few questions... What ECM are you using? Is it a 1227747? Can you post your bin file? Do you have the park/neutral switch input wired to the ecm? If you post your bin, the xdf, and adx file you are using to datalog with, people on the forum will be able to better help you.

In the spark advance table that area between 30-35 kpa, I'd change everything less than 20d to match adjacent cell. Target idle rpm is set at 700 rpm but your cam might be happier at 750 rpms. In the 30-50kpa 800-1200 rpm fatten VE by 5%.
Also your datalog occasionally flashed "Air Diverter"...Adjusting-VE-Fueling-tables-with-BLM-data-Tutorial!
