i can provide pics of me testing it and showing you the before/after "splitting" the signal and its signal values. I can get them up monday when i start testing various methods. (if it doesnt rain) And yes, there ARE resistors that stem directly to the IAT/ECT sensors.
For safest measure, you dont need to give the Fit ecu the ECT reading. If the signals are not accurate, your ECT will be reading a lot lower than it is actually, and the engine will constantly be working itself to get to warmed up temp of ~180. Resulting an overheating condition that you wont know about. (this is wat i DONT want to see happen) You can simulate ECT/IAT values with the use of different resistor values for the Fit ecu to make it think its "ready".
Again, this information was stated in my reports from the last project i worked on and is confirmed by Hondata. Although Hondata is experimenting by removing those certain resistors and/or changing resistor values on the ECU itself to amplify the signal enough to provide accurate readings between 2 ecus.
