The electronic one. Can u tell me about it and how it differs from the AVCR..

 

I have their new boost controller. It cost a lot more than the AVC-R or pretty much any other boost controller out there. It's pretty complicated to use and the manual doesn't tells you how to use all the features, which I think is pretty stupid. If you have the money for this boost controller than get it. It's really up to you.
