How can I see how much boost the VEC is seeing? Which sensor are you guys using for boost with the VEC; Analog 1 (Stock map sensor) or Analog 3 (Internal Map Sensor)?
Can I see boost on the VEC?

I T'd into the refference line, and ran it to a vac/boost gauge.
From the litterature that came with the VEC software, I believe that vec sends a dummy signal to the stock map sensor when under boost. The stock sensor is not designed to see boost is the reason.

Do you remember what size hose it was that ran to the VEC?
1/4"
The VEC has a very short smaller hose mounted to the unit, but I am not sure the size. My VEC came with an adapter to get up to the !/4". I ran my line from the back of the intake manifold (ROE SC) to a T then to the VEC. The T is where my VAC/Boost gauge gets its signal.

Thanks.
The VEC appears to have a 1/8" inlet. The adapter that comes with it is a plastic POS. I just broke it 
, so now I am on my way to the store for a new one.

Hope you didn't break it on account of me. I will buy owe you a drink if you did.
So does anyone have an answer on how to see the boost with the VEC program? I can map just about everything, however I can't find where it shows the boost.

No, I was wanting to blow out my boost refference line to be sure it was clear. It was unrelated to your question.FlyingLow said:

The AN3 (analog 3) box should be checked when logging.FlyingLow said:
Can I see what the timing is set at with the VEC software?
Yes
It is in the ignition section, but it is adjusted based off of the stock curves. I am not sure if the loggin software shows the overall factor. When I get my laptop, I will be doing a lot of investigation. I plan on running and logging all of the tunes that I got from ROE. Then I can see how the changes affect the result.

Looking at the logging instructions it does appear to only log the timing changes that the VEC performs. NOT the actual timing the engine sees.tinygiants said:
