- Adaptronic is utilizing that the factory engine harness connector is not fully populated. This gives the end user the option to purchase the pin's - 316836-1 and install them into the factory engine harness connector
- The factory connector has a locking tab that can be easily popped open with a pic. Then the properly crimped pin will slide right in.
Fuel Pressure Sensor Instructions - Fuel PSI Install
- Remove the BARO Sensor
- Baro Sensor Wiring Color/Function:
- Black/Red = Sensor Input
- Black/Blue = Sensor 5v Output
- Black/Green = Sensor Ground
- In Eugene under the input tab select Atmospheric Pressure Sensor and change the Atmospheric Pressure Mode to - Automatically measure from on-board MAP before engine is started.
- In Eugene under the Inputs tab select Liquid Pressure Sensors- Select Fuel Pressure Sensor - Select Sensor type for external fuel sensor - Choose your fuel pressure sensor type (Most common 0.5-4.5v (150 PSIg), Change the Source from Default to Ch 4 - EMAP_ext
- Note when the Fuel Pressure Sensor is activated it enables the engine protection feature which is located under the Functions tab - then select Engine Protection | Rev Limit - Select Fuel pressure and disable or enable it - Here is the instructions for Engine Protection.
Oil Pressure Sensor Instructions - Oil PSI Install
- Suggested pin locations for the Oil Pressure Sensor:
- 3O = Oil Pressure Sensor Input
- 3K = Sensor 5V output
- 3M = Sensor Ground
- In Eugene under the Inputs tab select Liquid Pressure Sensors- Select Oil Pressure Sensor - Select Sensor type for external oil sensor - Choose your oil pressure sensor type (Most common 0.5-4.5v (150 PSIg)), Set the Source to Default.
- Note when the Oil Pressure Sensor is activated it enables the engine protection feature which is located under the Functions tab - then select Engine Protection | Rev Limit - Select Oil pressure / Temp and disable or enable it - Here is the instructions for Engine Protection.
Oil Temperature Sensor Instructions - Oil Temp Install
- For this sensor we recommend removing pin 5U from the engine harness connector. This pin was previously used for the MAF sensor ground which is no longer needed.
- Suggested pin locations for the Oil Temperature Sensor:
- 3Q - Oil Temperature Sensor Input
- 5U - Sensor Ground
- Note temperature sensors are non polarity specific which means either side of the sensor can be used.
- In Eugene under the Inputs tab select Temperature Sensors - Select Oil Temp Sensor - Choose your Sensor type - (Generic would be use for a sensor that is not listed - you will need to setup your own custom calibration which is usually documented from the factory specification sheet) Leave the source to default. Click on the sensor Biasing and Filtering section and make sure the Bias OilT sensor Input pin is checked and the Filtering (ms) is set to 200.
- Note when the Oil Temperature Sensor is activated it enables the engine protection feature which is located under the Functions tab - then select Engine Protection | Rev Limit - Select Oil pressure / Temp and disable or enable it - Here is the instructions for Engine Protection.
Fuel Temperature Sensor Instructions - Fuel Temp Install
Fuel temperature sensor input is a little more difficult to accomplish - the reason for this is the same input for the fuel temp also is used for the cruise control option. So if you still want cruise control but also want fuel temp you will need to install a flex fuel sensor. If you do not care about having cruise control and still want fuel temp (less expensive then a flex fuel sensor setup) follow these pin locations for Fuel Temperature Sensor:
- 5V - Fuel Temperature Sensor Input
- Splice into 5U or 3M - Sensor ground
- In Eugene under the Inputs tab select Temperature Sensors - Select Fuel Temp Sensor - Choose your Sensor type - (Generic would be use for a sensor that is not listed - you will need to setup your own custom calibration which is usually documented from the factory specification sheet) Leave the source to default. Click on the sensor Biasing and Filtering section and make sure the Bias FuelT sensor Input pin is checked and the Filtering (ms) is set to 200.
Flex Fuel Sensor Instructions - Ethanol Sensor Install
- The Flex Fuel Sensor behaves a little differently then other 3 wire sensors. It uses 12v switched power and chassis ground.
- Pin Locations for flex fuel sensor
- 1A - Flex Fuel Sensor Input
- Pull Pin 5AF and use that wire for 12V switched (can also be used to power a wideband like a LC-2)
- Connect the ground to the ground location on the passenger side right next to the ECU enclosure.
- In Eugene under the Inputs tab select Ethanol - Make sure the Ethanol Source is set to CAS 3
- In Eugene under the Tuning - Fuel tab Select Fuel MAP 1 Settings - Change the Stoich Source from Constant to Flex Fuel (Ethanol sensor required) Once this option is select it enables all of the flex fuel maps. Here is Andy's video on Flex Fuel.
- Flex Fuel Sensor does more than read Ethanol content it also reads Fuel Temperature. In Eugene under the Inputs tab select Temperature Sensors - Select Fuel Temp Sensor - Change the Sensor Type to From Flex sensor.
Adaptronic Lambda Module Rx8 Instructions - Rx8 Lambda Module
- When you receive the package you will want to follow the instructions on the Lambda Module product page on this website for installing the actual module - Lambda Module Product link
- Once you have the module installed you will need to pin the 6 wires from the lambda sensor harness into the OEM connector - I recommend two options to getting the wires into the OEM ECU enclosure - Option 1 is to go through the vents for the ECU in the front of the OEM ECU enclosure Note you will need to cut the cooling plate inside of the OEM ECU enclosure which is recommend anyways for better fitment of the ecu. Option 2 is to drill a hole in the OEM ECU enclosure cap and fishing the 6 wires through with a grommet to help with keeping it water resistant.
- Now that the wires are inside the OEM ecu enclosure you will want to pin all 6 wires to their associated location to read and operate the lambda sensor. Before you insert the pin you will need to unlock the associated connector that the pin location is at. You can go out and purchase pin removal tools but a simple pin board pin works very well for unlocking the connector. The lock is on the smooth side of the connector and you use the pin board pin to lift the lock. The pins only go in one way and should slide in easily - you should feel each pin click as they go in and you will not be able to pull the wire back out. If you do make a mistake and push the pin into the wrong location on the front of the connector each pin has its own individual latch locking the pin in. Use the pin board pin to lift the latch and you should be able to pull the pin back out.
- Black to Pin Location - 1E
- Green to Pin Location - 1H
- Grey to Pin Location - 1K
- White to Pin Location - 1N
- Yellow to Pin Location - 1R
- Red to Pin Location - 1X

Mazda Rx7 FD3S OMP To Rx8 Conversion Guide:
- Sensor ground, 5v, and Servo input will needed to be wired separately as the 2 addition wires (8 total to the Rx8 OMP) will not be used. As for the Sensor ground and 5v reference you can see there is multiple options on the Rx8 ecu to splice into or pin directly into the ECU depending on how many other extra sensors you are using. The APV motor connector has the sensor ground, 5v, and servo input already so you can use a connector kit to utilize these 3 wires. Please look at the wiring guide to confirm the wire colors for the APV motor.
- The OMP also needs 12V power on 2 of the pin locations opposite of S1/S3 and S2/S4 The wire color on the Rx8 Loom is White/Red.
