Hiya, I have been using Black V2 on my supercharged TT VR6 for a while & wanted to change to V3 so I have merged data from the Work In Progress BUB file with my converted V2 map.

The car fires up easily & seems to run on all 6 but dies almost straight away…unless I un plug Cam 2 solenoid then it will run ok, idle, rev up etc & sounds relatively good.

I am no expert in this field so any help would be greatfully recieved. I have tried changing Cam 1 & 2 parameters but getting nowhere.

It is a R32 BUB PNP with an eaton M112 Blower running a 2.5mm Head Spacer, forgot to metion that.

Log file & Scope file attached in the hope someone can spot what is wrong, TIA, John.

Disable both vvti. The problem is with the vvti settings. In the directory Base map, there is a base map for BUB engine. Please copy trigger settings and vvti settings from this map. It is proven and works well.
