We have a twin wren 44 powered ME-262 and have been trying to get them running for the last two days. One motor imo is rubbing and will not achieve enough rpm to get an idle. The other spools up to idle (60k) and the gsu says running but when we disconnect the glow and shut down the gas the motor starts to lose rpm and eventually shuts down?? We have not changed of tinkered with the factory ecu settings. The ecu is a fadec 302. We are also usng powermax for starting gas.

Thanks,
Vin...
