Here you go the startup idle should be fixed now, i will need another datalog.

I found time to adjust the tune file for you. Looks like we are making progress.
cold start idle oscillation likely from low rpm, this should fix it.
Sorry should have specified, that is on purpose now I should have the needed information to build the closed loop idle program.Its idling to high. I tried to bring it down with my idle control adjustment plate, but it only came down slightly. I am on the east coast also. Available most days around 9pm for a remote. Thanks

lets try this out.
Your car is insisting on being difficult... lol. Are you using a standard ford IAC motor on the car?Car starts off with some surging at idle. RPM"s shoot up to almost 3000 RPM when tempts get up to 180*

GGRRRR..... try this...... if this does not work i will have to do some archaic tuning methods in the control algorithm... lol..Still idling high.

what firmware are you currently running?
What cam is in this engine? is it a lump cam or closer to stock??
gotcha i will try and tune it down as close to stock idle as possible, however there will always be a small amount of oscillation in the idle.Lump camTrickflow stage twoTFS-51402001

Hopefully this will take care of the really high warm up idle and the oscillation in the idle. If we can get this nailed down tight i can lower the idle speed some [i would like to get it down to 800 or so]...I didn't get time to go for a drive but I was able to get the tune loaded and let it idle with some revs for a bit. There's still some surging here and there but I'm not convinced it isn't hardware related as my stock throttle body sucks out loud and has a really sticky movement from full closed to any other position. Then there's the IAC, no idea how good it is. I'm already planning to get an Accufab 70mm in the next few weeks so I'll just get a new IAC while I'm at it just to eliminate that as a possibility.
Only thing i can figure is it did not respond well to my attempt to richen the idle up. new revision for you.Ok, took it for a short drive. First thing I did was upload 1.2 tune and start it up... forgot to start logging for the first few seconds but then after a few seconds of running and logging it was getting a new popping noise in the exhaust so I killed it and put version 1.1 back on it. Started it up again and all was good, or at least same as the other day. I drove to the gas station, got a drink, then came back home. There are 3 logs attached with the shortest being the 1.2 tune for just a few seconds. Then 1.1 tune going to the store, and 1.1 coming home from with a few 2nd gear short pulls as I didn't want to attract too much attention just yet and wasn't in Mexico.
