I had Hondata S300 on my all-motor b20vtec.
Dyno-tuned. It was pretty much a necessity for me because the motor wouldn't even idle let alone run without a full stand-alone, so i'd say I was happy with it
I also had a Hondata S200B on this motor (it's a long story why i had to get the Boost option...but it came down to the ITBs)
The link in my sig will tell you the specs of the motor.
IMO, You can get the most expensive standalone money can buy, but if you can't find somebody that actually knows how to tune it and use all the features you need, then you've just bought a really expensive VAFC/SAFC.
