I wouldnt bother, you arent getting your standard v3 ecu mapped so only thing you can do with avcr is turn up boost, which is a big no no. Avcr are most used with an apexi ecu, and they are good bits of kit that allow different boost etc etc, but are mapped for!!!
Dont bother, when you get your Simtec, the ecu will have all those features built in, so avcr will be redundent anyway
