Need help getting started vortec tbi

Dave,
Thank you, will try tomorrow

Dave,
Progress was well made today.
It needs to be dialed in, but I feel my truck is at 80- 90%
You have no idea how nice it is to run this thing.

I am having trouble with my thermostatic control (not computer controlled) and need to tweak a few things mechanically.

I looked at the injector flow that was entered before I started
Did you tweak it for me?
It was spot on

Do I need to enter a new value for gear ratios because my differential has 3.73?

Attached is a data log for if you get the time.

I looked at the data log. Attached is a screen shot of what I'm seeing.

There is not a parameter for gear ratio.

The .bin file I posted is based on both the information you posted, and my tuning experience.

Overall, it appears you have a good starter .bin file to work with.

Enjoy,
dave w

After looking through the basics of the .bin and driving the truck I am getting a feel for what needs to be changed.
Im having some issues running rich.
I had the truck stall under load at a stop sign (possibly due to running rich).
Know where I can find a resource for getting advise on how to change spark and fuel parameters and diagnose?
Also what is ideal for injector bpw?
I was digging through the constants and saw the cylinder volume was set for a 350.
I have a 357 and was wondering if I should expect changes if this was altered.

(PS idle rpm in park and drive seems too low, I haven't made any changes yet).

Truck runs great other than needing tweaking.

Dave do you remember what injector setup was used on the bin? size/ pressure?

[Roadknee]

Did you set your initial timing to zero with the connector unplugged? I ask because your engine is idling around 60kpa manifold pressure which is high for your small cam. IAC is also pegged at 150 counts.

Look at the parameter RPM/VSS ratio to adjust for your gear ratio. There are instructions in the parameter comments.

This will be my next attempt.
Deadline at work has me drained.
This was the parameter I remembered seeing.
Thanks Roadknee

I'm always challenged, am I a moderator or a business owner? As a moderator, I provided good information. As a business owner I've shared a .bin file that others paid $$$ for. Is it fair for me to say, run with the information I've provided and figure things out? Is it fair for me to say, send me a PM and lets figure out a business transaction?

In the game of chess, I say check ... your move.
