What are the chances the RX3S ECU works on the SG400? Both have TC380 motors...

Thoughts? I'd love to have an ecu that wasn't purposefully tuned to have a flat spot right at cruising speed. Can't find an RE3 ECU anywhere but I can find an RX3S ECU on Aliexpress.

Charles, Try GoBoom on ali. I'm the guy that first tried and shared that the non Euro non EPA ecu they offered would improve fueling on our epa compliant RX4 with nc450.
My guess, based on the above, is that an ECU not marked EPA/EU for the TC380 will be an improvement.
