I can’t connect to my ECU
- Check the red and orage wires on the main harness, should have over 12 volts. If you are under 12 volts, the system will not activate.
- Ground wire on main harness must go directly to the vehicles battery’s negative post. The chassis of the vehicle is never a guaranteed ground.
- The ECU should be mounted inside the vehicle. Connecting just the red, orange, and black wires on the main harness will enable to check the signal strength. Should be between -40:-65 for good connection strength. If your not recieving around these numbers, relocate your ECU. If you are ABOVE -65 you must move your ECU.
- Interference from other items, such as compressors, speakers, amplifiers, and sound deadening materials, will limit the bluetooth strength. The ECU must be atleast two feet away or more from these components to ensure proper signal strength.
- If you’re losing signal after connection, this can be a sign of low voltage or poor grounds for your ECU, Manifold, Compressor, or Compressor Relays. Bad grounds cause higher amp draw, resulting in a voltage drop.
- On-screen Voltage reader, on the top of your screen, is used as a tool to indicate if you have a high amp draw situation. When operating the compressors, or the switches, and you see a greater voltage drop of more than .3 of a volt, this is an indication of ground issues with the above components and/or the vehicle’s alternator is not providing a sufficient charge to maintain voltage required.
PLEASE NOTE: The way to test your valves, is to press and hold both up for front and rear, and watch the voltage reader at the top of the screen, if you see a voltage drop more than .3v as described above, you more than likely have an improper ground.
*Note We reccomomend vehicles with with air suspension, and other aftermarket options (including stereo systems, aftermarket cooling fans for radiators, ect.) will dramatically increase the amp draw on your alternator, and we reccomend a high charging output at idle alternator (We use Autotech Engineering). 220 amp is a minimum requirement for most vehicles. Most of our installs where vehicles have all of the above modifications, run a 330 amp alternator.
