Today I had the opportunity to test CarbOnBal side by side with a CarbTune Pro unit. Not only that but more experienced tuners got their hands on it for the first time and it resulted in a lot of enthusiastic responses.

It took a while to get the damping set up right but we got it tuned in. I'll set this up as default preset in the next version. 

I noticed that one of my vacuum lines was a fair bit longer (more than a foot longer) than the others and this affected the readings a lot. Note to builders: make all the vacuum hoses equally long!

The other thing we noticed right away is that the relative centered display auto zooms way too aggressively. This needs to be more stable because it tends to make the balance look a lot worse than it is. It is in effect 'too accurate' to be easily usable. We ended up using the absolute display to get a good comparison.

Bottom line:

Looks like there will be some software tweaks coming up, and the hardware works well.
