I am a long way from go cart mode, but figure I’d throw this question out.
I plan to run a Gen V LT4 Engine with a Stock ECU, not a crate ECU due to emissions compliance. Also planning on using the stock ECU to control the brushless fans I picked up. Not sure what temperature they turn on but assume the programming is designed around the 212 degree thermostat. I don’t plan to mod the engine.
The question is, should I consider going with a cooler thermostat. The stock thermostat opens at 212 degrees. Many of the aftermarket companies offer a 160 degree thermostat. If I go in that direction I could modify the ECU program to turn on the fans sooner, or use the SPAL brushless fan switch that came with my kit which ramps the fan speed from min to max as temperature rises from 165 to 175 degrees.
Not sure if the stock engine programming will be happy operating at 160.
Appreciated the feedback.
