Hi Chad,
Just for closure. This issue disappeared as quickly as it came to light. Have had two very excellent extended sessions since my first post. The starts are perfect. I did adjust the ECU burner preheat time (#48), from 14sec to 20sec. This has sorted the issue out. The starts are still as quick as before.
Infact, the 180vx start sequence is so much faster than some other new turbines.
All is well...good weather on its way....more time to burn Jet A1....excellent.

Still waiting for news on a EvoJet 200plus......might have a model next year that could do with a 200-220....

Have great Xmas.....
