Innovate LC1 and XD16 Wideband Installation
(including connection to e-manage ultimate)
Innovate Motorsports offers a wideband solution to monitor and log wideband O2 sensor activity. This is a vital tool for tuning your tuning and a getting the most power as safely as possible. In these instructions I will also cover connecting this to Greddy's E-manage Ultimate and using the A/F target map feature of the E-manage.
According to the manufacturer, it has the following features:
InThe Innovate “Standalone Gauge Kit” comes complete with the NEW! LC-1 Wideband Controller, NEW! XD-16 Programmable Digital Gauge, Bosch 5-wire Wideband 02 Sensor, Bung/Plug Kit, Software CD, and owners manual.
The LC-1 is a complete wideband controller built in to a sealed cable. It features the same award-winning patented digital measurement principal found in the LM-1, and includes digital input, output, and 2 programmable analog outputs.
The Innovate XD-16 dash-mountable Digital Gauge features programmable LED colors and remote control button to start and stop LM-1 log sessions or initiate calibration. The entire gauge is a mere .750" thick, so it's possible to mount even in surface mount configurations. The display features a 3 character central LED display, remote control button, and a programmable digital needle. The body is a billet aluminum bezel.
In no way is this an endorsement of any product mentioned on this site, this is just documentation of my process. All repairs should be carried out by someone who has the expertise to do so. These should not be considered a complete set of instructions; the author bears no responsibility for any damage, personal injury, death, flood, fire or pestilence that may occur as a result.
Requirements
if you click on most pictures they will get bigger!
| 1. | The first thing you will need for this installation are the manuals and updated software. Manuals can be downloaded from the right, updated software and firmware from the link above. Contrary to normal trends in the quality of instructions for tuning products, these manuals are well written! | LC-1 Manual |
| 2. | Find a good place to
locate the LC-1 Cable. This should be away from the heat but close
enough that the O2 sensor cable will reach! I selected this place
behind the front tower brace to the right of the ABS unit. I held it
in place with automotive strength double sided tape and then firmed up by
putting black RTV silicone around the edge of the tape and the unit.
This was my decision as I didn't want to drill into the body due to the
highly corrosive nature of Russian weather!!
Next route the cables into the interior; to do this I cut a small hole in the main wiring harness bung where the main ECU wires go into the car (be very careful) and then sealed it all back up with more black RTV. |
 |
| 3. | Remove the stock O2
sensor. The location will vary depending on what headers you have on
your car or if you have an SR20DET, in which case the O2 sensor will be on
the elbow after the turbo.
To remove the O2 sensor I have a proper O2 sensor socket which is a long socket with an opening up the length of one of the socket to allow for the sensor's cable. Obviously you should disconnect the O2 sensor plug before you do this! Now install the new wideband sensor - note with my aftermarket headers I had to do some modifications to the brake lines to make this work properly - probably not a good idea! |
 |
| 4. | Connect the new O2
sensor to the LC1 controller and then access the on the interior of the car.
Check the instructions for your LC1 controller - there are 2 versions one
with 7 wires and one with 6 wires. Next access the ECU which is located in the passenger side footwell under the side kick panel. |

Now you will need
to splice into the wiring harness as follows: Red (12V ignition) splice into 47 Blue and White go to ground - I picked a ground behind the ECU where the ECU itself is grounded. Yellow connect to pin 19 (cut and join) Green (if you have it) connect to pin 21 (cut and join) Black (if you don't have an XD 16 gauge should be connected to ground via a momentary switch. This needs to be pushed for calibration. If you have an XD16, just tape this up. Page 5 of the manual shows how to connect without the XD16. I strongly recommend using an LED if you connect like this so you can see what is going on. |
|
| 6. |
If you have an
XD16 find a suitable mounting location (I still haven't decided on a final
solution so mine is temporary held in place with tape). Connect the
XD16 to the LC1 2.5mm stereo plug - don't forget to terminate the chain as
shown in the manual! Now you are ready to calibrate the LC1 - this is really important and the instructions are very straightforward in pages 9 to 11 of the manual |
