Lotus Race Dash and Data Logger

This project consists of a Race Technologies Dash 2 as well as their DL-1 Data Logger. The entire install is 100% converted back to stock if so desired.

The D2 along with DL-1 gives the user the ability to display a multitude of live and logged data, toggle between 5 user defined screens, create lap markers, utlize GPS mapping and speed display, along with a host of other options.

This car is setup with the following sensors that can be displayed and are logged:

• TPS, tapped OE sensor
• RPM, tapped OE coil common
• Wheel Speed, tapped OE Sensor
• GPS Speed, DL-1
• Fuel Level, tapped OE sensor
• AFR (wide band), NGK AFX
• Water Temp, tapped OE sensor

All OE taps were done at the ECU. We ran two CAT5 wires through the engine bay grommet under the ECU to the Dash2 and DL-1 via the shifter spine in the cabin.

The pinouts for the stock Lotus cluster are as follows:

• A1- ABS 12volt (tied to odometer, non CAN)
• A2- Ground
• A3- Fused IGN Power
• A9- High Beam Indicator
• A10- Alternator/Charging System light
• A11- Left Turn Signal
• A12-Right Turn Signal

• B1-Brake Fluid/Parking Brake Indicator
• B3-ABS Warning
• B4-Seat Belt
• B6-Parking Lamps (illuminates cluster when lights on)
• B7-Alarm indicator via shift light
• B8-Fused Power via Cabin fuse #3 (under dash)
• B11-Warning Buzzer (tied to door open/close switch)
• B12-SRS Airbag warning
