ST-12 Quickstart Guide

Installation Tips

  • Mount Sensor Bungs 8” or more away from the cylinder heads.
  • Use double length Bungs.
  • If needed use new style open hole HBX’s. Mainly on high horsepower or high output engines.
  • Make sure that the ST-12 box is plugged into a Grounded outlet. That includes a grounded extension cord if used.

Operational Tips

  • Perform Free Air Calibration when changing engines on your Dyno. Especially when Sensors are new.
  • Warm up sensors 5 to 10 minutes before making a pull.
  • Avoid flooding the engine with the Sensors mounted in the exhaust.
  • Extremely rich air/fuel ratios with leaded race fuel may lead to premature Sensor failure. Try to make sure the engine is close to reasonable air/fuel ratios before installing Sensors into the exhaust.
  • If inputting external sensors into the ST-12 box make sure, you run individual grounds to the Negative terminal of that sensor input.
  • In addition, it is a good idea to run a ground from the engine/ignition ground to the negative terminal on the ST-12 marked 12-volt ground.
  • If you need to extend the Serial output of the ST-12 to reach your computer. Purchase a serial cable extension. If using a USB to Serial adapter, do not use a USB cable extension over 10 feet long.
  • If you use your computer for several of our Innovate devices (LM-1, DL-32 & or ST-12) you should save your input descriptions for each device after you have successfully programmed that device. This also holds true if you do tuning on customers cars or engines that have different Innovate hardware installed. This will save you the time of reprogramming these devices as you switch back & forth between installed applications.
  • All of Innovate’s User Manuals are located under Start/All Programs: LogWorks2. Or they can be accessed by clicking the Support link.

 Troubleshooting

  • Do a Heater Calibration & Free Air Calibration if the Sensors seem to be acting unusual or after installing New Sensors.
  • A Sensor that performs normally at idle then constantly errors out, under power. Most likely has a crack in the internal ceramic section & needs to be replaced. This most commonly happens when a hot Sensor is splashed with cold fuel (flooding) or by rough handing or dropping the Sensor on the floor.
