Koltec VG392

Postby sbf » Sun Apr 04, 2010 12:13 am

Hi everybody.

I'm from Portugal and I'm in need of help on a Koltec vg392 system, instaled on a 2001 Daewoo Lanos. The symptoms of the car are presently a big fuel consumption on lpg and lack of power. While running on gasoline the car runs well, good response to acelerator and good engine sound. On running on lpg, engine sounds weird, it seems it misfires and hesitates on increasing rpm while acelerating.

Exaust emissions are these:

Gasoline, hot engine:

3000 rpm / idle

LPG, hot engine:

3000 rpm / idle

Spark plugs

In Portugal there is no more anyone known able to assist this system. Please help

Regards

Thank you

Hi

You need someone with a Koltec diagnostic kit to check the LPG ECU and re-tune it?

Yes. I wonder if anyone here knows where/how to find such software to read and tune the lpg ecu.

By the data given above, what is your opinion about the condition of the system?

Regards
