High idle regardless of whether it is cold or hot

[dell_mare]

a best dual fuel systems, as seen on new cars..
is a new ECU that sthe engine in both modes correctly
for sure in LPG, it must be tuned for LPG spark needs.
based on fuel type, load and rpm. and driver demand,.'

so what things did you add to the stock car .>
sure LPG
but did it add air valves there, and it yes are those turned off, in petrol mode?

I didnt add anything. LPG was already added, tuned, and attested (by traffic law here). I dont know about those valves. Maybe I can upload some pics to show how LPG installations look like.

Anyway I forget to tell about Vitara driving performance:
Max speed I did: 130 kmh (80 mph) - there is a long way to go in fifth gear to get that speed.
Mileage driven: 1242 miles in a month / oil color didnt change and oil level is the same from start
Acceleration to 100 km/h: not tested
