View Full Version : Check out my tune?

Hi All,

Just wondering if a few of you can browse through my tune. It will start and idle OK, but any throttle input and it will die. I haven't tried to drive it yet but I don't even think I can get it down the road without it killing a bunch.

several maps are from a similar setup that runs well and I just copied them over. This includes timing, VE, misc spark control, etc.

My setup-
'99 LS1, stock heads/stock bottom end
227/243 .62Xish lift cam, I can look at cam card later for exact lift
P1SC blower, 3.4" pulley/stock balancer
2 bar map
current injectors are 60s but I am swapping to 48.5lbs after having issues with them.

setup is a retrofit in a '49 chevy pickup with a T56.

Tune is setup for COS5, open loop speed density.

My current goal is to get it running and get it around the block a few times.

Does anything stick out as wrong or far from what would be normal? I know idle and such is tuned last- but I am so far away I feel like I can't get it down the road.

Any help is appreciated.

-Dustin

Hi Dustin,

You injector flow table is wrong.

What injectors do you have, and is your fuel system pressure referenced?

VE table is pushed way down in the idle region - its probably going super rich as soon as you move out of that area.

Hi Darcy,

Thank you for the review. I attached my current file with the stock injectors. The one above was with 60s and were numbers I found here on efilive forum.18160

I have MAP referenced regulator- so I should be basically horizontal across.

Is it worth it letting it warm up and attempting an autove before I leave the garage? To see where the VE table wants to be just to make sure I can make it back home?
