For some raison youboob have blocked the commentaries, but I did get a private message that Wrens advice was to push the acc delay from 008 to 017, i did but slow and unstable so I put it to 010, that seems ok.

 

 I also dropped the End preheat kero from 200° to the factory setting of 180°, but no difference still staying for ages at 9.000 rpm,,

Thanks it seems sorted,, thanks to a couple of 'followers' I changed the rpm preheat kero to 10.000rpm and the egt end pre heat to 120° ( advice from Gaetan at the french kero forum ) and you will see that all went well, maybe a flight in the afternoon thanks,,, i also changed the Acc delay from 008 to 010 pump start point 030 pump start ramp to 005 egt end preheat 120° preheat fuel 040
