Foot Long Flame behind P120 & Fuel Floods
Need help plz,
I borrowed an used P120 (Engine only) from a friend, I just swapped the engine on the aircraft ( Older P70 to new P120). I change the Key 2: 41- engine feature to P120 on My ECU V5.0
P120 On Propane Start: engine ignites well and in 10 secs we see the long flame coming out from the rear...and it only gets bigger. (Kindly note: when i put my old P70 back on the aircraft... it starts well)
So Far: I have changes the UCCL1 & the UCCL 2 to lowest , fuel purge test (ok) no air in the fuel line
P120 Engine just doesn't get to Idle and never to the Max RPM ( ignition time out most of the time), WE even tried manual ignition.... only flaming trough t the exhaust & engine is flooding with fuel

are you sure you selected P120 not P120SE or SX ?, are you sure that your borrowed engine is 120 ? in my experience i had a similar problem when i don't select the right engine in the GSU, nothing to do with the fuel pump or solenoids since they are working fine in the P70 engine.
