I got my woolich racing log box last week, I Dled the current version on ecueditor.com and started tunning Im currently running a gen1 1397 engine with a Gen2 head cams TB's wiring ECU ect ect.. I thought tunning would be harder than this, litterally I didnt think my tune would be anywhere near close to start so I went on a few short runs around the block apllied teh changes and then went further apllied changes and then further.. Bike hasnt even been running a week and Im about done. I am completely happy with this system. (also using a zeitronix zt-3 wideband for AFR input to ECU pin 12)
