omvl dream xxi lpg system - anyone know how to retune it? I

[mrLongstaff]

morning all

as above states, I have bought the cables and the software and need urgently to retune the ecu following engine rebuild and tune up.
Has anyone done it for this system? Is it easy? Its on youtube..

What things in the software options will stabalise the system? It currently stalls on tick over as it cant find a constant level. Its perfect on petrol.

thanks for looking.

What things in the software options will stabalise the system?

If doing something in software options would stabilise running on gas on any vehicle, there wouldn't need to be that option in software! We would need to see readings from software etc to advise.

To answer Dai's question you may need to look at the sticker on the ECU. Also, what vehicle and model year is this?

many thanks for the comments.

my ecu just says 'dream XXI Injection System C'

i'll try and find an earlier version of the software from somewhere.

yhe lpg system fuse. I havent seen that. I'll disconnect cables from ecu at weekend to try n find it.

i have both connectors to try. the usb from laptop connector from the ecu is 8 pin female. but as its been there for 11 years, maybe thats dirty and not connecting?

thanks again.
