This block is used to set up open loop cam control with TPS limits. It is also used to open variable intake runners found on some engines like the Lexus 1UZ VVTI. In some cases, part of this block may be hidden or disabled. Note: This feature is only available on specific firmware. ask your dealer on it before you buy.

Cam1

In this block the output will be on between 2100 and 3900 RPM if the TPS value is above 30%, This is how most V-Tec cams are applied. The driver output will indicate where the solenoid must be connected on the ECU. Cam 1 is always used for the Intake cam or Cyl1 bank cam.

Cam2

In this block the output will be on between 2500 and 4000 RPM if the TPS value is above 30% as above. It operates the same as Cam1 but for the exhaust cam or bank 2 of a V type engine.

If this block is made visible like above, then it is only to indicate which driver is used. This may be in the V type engine where both cams settings are the same.

The intake flap

This block is firmware dependent on control according to requirements. For Toyota V8 the flap will be powered or activated whenever the RPM’s are between 2500 and 4900 in this sample regardless of throttle position. It will also be powered if the throttle is less than 60% depressed regardless of RPM. Said in another way, the flap will not be powered at over 60% throttle and at lower than 2500 RPM or higher than 4900 RPM.
