i buy a behotec j66hp and i can not make it start
i am doinf calibration run ,the turbine start to spin the propan ignites its spin to 21000rpm and then its shut down and as error it shows no acceleration during start up please help me the ecu is a projet hornet v5.2

First check your temperature READING. Make sure its reading between 150 / 200 degree during ramping. If the temp ok next remove you fuel line from the engine and check for fuel at 21,000/ 25,000 RPM during startup. If there is no fuel then check (FUEL PUMP, FUEL SOLENOID VALVE, OR ECU UNIT).


Hope this help

Hi,
check if there is enough fuel coming during start up.you can do this by pressing the little button on the ı/o board(the board with the little lamp)..You should here the pump when you press it...if not you have to increase the pump start up voltage...

All above is valid assuming all cables and tubing is correct and leak free...

Eray

what battery are you using i also had the same problem first i used a jetcat ecu battery pack .
but that diddent work because that is 7,2 volts then i used a lipo battery pack 2s1p 8,4 volts
that was shligtly better only fore the first start .
then i ended up using a lipo battery pac 3s1p 1500mah 12,4 volt then the problem was solved.

BUT CHECK YOUR MANUAL IT STATES WHAT BATTERY PACK YOU SHOULD USE .
IN THE MANUAL FOR THE BEHOTEC JB 130 IT STATES YOU SHOULD USE A 8 CEL NICAD BATTERY
OR A 3S1P LIPO PACK THE MAXIMUM RATED VOLTAGE FOR THE ECUIS 12 VOLTS SO YOU COULD TRY IT WITH A 3S1P LIPO PACK (BUT AT YOUR OWN RISK).
ALSO LOOK AT YOUR GAS PRESSURE FOR STARTING

Γειά σου Κώστα,

Κοίταξε να δείς αν το thermocouple probe είναι αρκετά μ�*σα στον κώνο της μηχανής και αν η θερμοκρασία ανεβαίνει μετά που θα πάρει μπρός.

Χρήστος

That's Greek to you guys!!!!

Thanks
but i fix it the problem was finaly from the ecu i made a reset i program it from the begining and all now is ok .
