OK, not flying until tomorrow but grabbed 5mins in the fading light to run the new ECU mapping.

Oh my God - what an improvement!! Quicker than a 160SX I reckon. Idle to full power was 3.9s, from just above idle to full was around 3s. Quick opening/shutting from various rpms showed no signs of faltering or overrunning etc

Looking forward to flying it now!

Well done JetCat. You got there in the end. Going to be a cracking engine I think

Rgds,
