I just caught this!

First thing to check : If there is too much propane on the initial start cycle , the rpm and temp will build quiclky, which will fool the ECU and slow the first fuel ramp. Check also that the EGT probe is inserted in to the cone to feel temp rise correctly

Go into the start menu and check to see what the setting for pump start ( Auto +1 recommended) and ramp (006 to 008)

If you have the Fadec software, you can also go into the autostart menu and reduce the rpm at the first fuel ramp.

If it is an older version (MK2 ??) there may be a restrictor installed after the pump ( 3mm piping with a small brass -needle) if this is present, try removing it.

Just a couple of suggestions.


let me know how you get along!
