Vortec and cam tunes

[kacy]

Standard disclaimer ... Likely goes without saying, but here goes anyway ... The .bin files I've posted work well for the vehicle it was originally "Tuned" for. Individual "Tuning" results can / will vary. There is always possibly of damage or personal injury. Use posted .bin files at "Your Own Risk".

Always use a Wide Band Oxygen Sensor when "Tuning". When playing poker, trust everyone at the table, but it's a good plan to "Cut the Deck".

Considering the expensive nature of building an engine, why would anyone not use a Wide Band Oxygen Sensor when starting up / breaking in a new engine?

The "Ultimate EFI Modification" is spelled "Tuning".

Absolutely, was just looking for some place to start with it. Isn't wide band o2 and narrow band offline at first start?

Most wide band O2 sensors (WBO2) have a warm up time of about 30 seconds. Connecting the WBO2 to ignition power with power in both "on" & "start" is a good plan. With "Key On / Engine Off" for about 30 seconds will have the WBO2 warmed upped and ready to go when the engine is "cranking / started".

The narrow band O2 is usually showing BLM = 128 until the computer goes into closed loop. Usually, the .bin files are programmed for closed loop after the engine reaches 135 degrees Fahrenheit.

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.

I haven't had a chance to try the idle set procedure as I just got back and its sub freezing here again. When it warms up a bit I will try the reset procedure.

@davew do you remember if that tune was to work with stock pump and psi or TPI pump and 18 psi?
