Play of course!
For one thing, thats why you went for VEMS, so you could get stuck in and have a go.
And second, it ain't gonna fix itself.
The important bit is to be meticulous with your record keeping. Last time I did start calibration work I made a simple sheet with date, ambient temp, coolant temp, calibration name and log name on it, and filled it in for each start I logged. Later on (end of the day normally), I looked through the logs and added time to fire, peak flare (this is delta above target), lowest lambda (rich dip) and any notes worth mentioning (speed dip, lambda went lean etc etc). This allows you to quickly go through and see what is good and what is bad, and pick the calibration settings accordingly. You can then steadily home in on a good calibration. As you build up this databse of info, you will also start to get a 'feel' for what the engine wants, so if you do find a poor start in the future you wil have an idea how to sort it.
Go for it!
BTW have you got the lambda working right from the start yet? This will really help you out with knowing which way to go on the fuelling.
As long as you save the changes and note what is good and what is bad, you can always step back.
