### Notes
* Use of 2 wire temperature sensors is **highly** recommended. Whilst 1 wire sensors will work, they are almost always considerably less accurate
* Use of 2 wire temperature sensors is **highly** recommended. Whilst 1 wire sensors will work, they are almost always considerably less accurate. Running a dedicated ground wire back to the ECU from the sensor is also recomended.
* The external MAP sensor in the above diagram is optional and may be omitted if the onboard MAP is used. Alternatively an external Baro sensor may be added in the same was as an external MAP
* A 3 wire variable TPS is required. On/Off type throttle switches are not suitable
