Do you need to go to a dyno to get benefit from data logging? Can you just plain old data log?

 

Yes you can, although he/they want the A/F ratios.

you could install a LM1 or other wideband A/F logger and use the Xcal2 for everything else. But why, going to the dyno is fun. Shop around and find a good shop. bring some buddys and make a day of it. Look for a shop having a dyno day. the cost is much less.
