Default EMU Problems

Just wondering why when i have the Coolant temp wire hooked it screws around with the ECU coolant reading? its like the EMU is taking voltage and giving false readings to the ECU. Example when the wire is hooked up the dash will not go past 2 bars no matter how long i let it idle for. The EMU is rading around 60 C. as soon as i disconnect the wire the ECU see's the correct temp (3 bars) and the fans will start working. Jumper 13 and 14 are set to 1-2. is this right? and what should my coolant temp and intake temp tags be set at?

Don't run it. The guide here on s2ki is wrong about the coolant temp.

The issue is it will change the fueling according to the temp sensor in the wrong way. I would just trust that the ecu without the emanage will handle all the temperature calculations.

If you want to save yourself a ton of time and get a really good tune I would purchase a pretuned from Ballistic Motorsports. It will be configured correctly and be within 1hp of a custom tune.
