    Turbo RPM calibration

    Hi guys, turbo speed question once again. I was almost happy after FW update, but... As help file says: calibration number=6000 x number of teeth (number of compressor blades) / Divider. Lets take Borgwarner EFR turbo with 14 blades and borgwarner speed sensor with 8 divider. So calibration number should be 6000 x 14 / 8 = 10500, right? But software is limited to 10 000. Is there any reason for that? If I will use 1050 calibration instead of 10500 I will get correct number except missing one zero? For example instead of 50krpm i will see 5krpm? EDIT: calculated answer to my second question, and actually I will see one zero too much. For example, instead of 50krpm I would see 500krpm. BTW, its G4+ Thunder.
  2. Hi, when switching between TC slip threshold tables while TC is in lockout (requirements are not met to turn it ON), tables are not switching. Basically its only misleading, but I believe it works fine, because when TC turned ON, it switches table. But I would say that it should be switching straight from switch, ignoring lockouts.

    Trig2 or DI1 or DI2

    Thank you very much. This is what i was thinking about. One more question. There is no way to wire both cams to DI 1-4 to monitor both angles? For example if i choose in VVT setup bmw dual vanos it wont sync, because i suspect cam tooth number is hardcoded in ecu?

    You are right, they are not variable. But having cams angle in the log would really make it easier to tune sprockets on the dyno. Also it would be early warning when chain is worn out and its length is changed. But if ECU knows piston TDC position, why it cant say cam position even with one tooth? I dont get it.

    Trig2 or DI1 or DI2

    Hello, i have custom trigger wheel on f20c and I want to see both cam angles in logs. How should I wire it properly? Should I wire one cam to Trig2 and other cam to DI1, or should I wire both cams to DI1 and DI2? Will I be able to setup it in software? Its 24-1 and 1 tooth on each cam. Thunder ECU. Thanks.
