adjusting screws inside lpg computer box so i can start on lpg only

[seanshed]

somethings up with my fuel system and had to leave vt at work
I remember seeing a post a year or more ago were someone new which way to turn one of the 2 blue adjusting screws
inside the lpg computer box so that there is no startup time running on petrol before it switches to lpg
it is a italian system forgot which brand

[strgas]

have you got a picture of the lpg computer

[seanshed]

no was a ezygas installation, i am leaving now to see if i can get it to start

[strgas]

can you see a number on the module 299 294 ???

[seanshed]

it is a sprintgas system, AEB 297 self learning feedback system, blue box with removable little rubber cover underneath is 2 small philipps screw electrical adjusting pots, the question is with one is the timer,

[strgas]

will check my paper work for this model processor and get back to you

[strgas]

finally found my paper work but not for the 297 module , going by the 295 module the RPM setting is done via the left hand trim pot clockwise for less rpm anticlockwise higher rpm

[seanshed]

so what you are saying is that it waits for a certain rpm before it changes from petrol to lpg
In that case it is not posible to start on lpg only, it still need petrol to turn over

[strgas]

it can be set low enough to give a short prime time on petrol then crank and run on gas , from memory that module has a gas only start function , turn ignition on and hold the selector button for 5 sec i think it should engage the lpg system and gas only start . try that and see what happens

[seanshed]

what does the other screw do and do you mean it switches to petrol at high rev

were do i get information on this lpg system

thinking of putting pod filter on but not sure were i put airflow sensor and the pipe runing from mixer to hole in airbox

what plugs, leads and gap size so i get

would like to have it running as dedicated lpg

[seanshed]

turning the ignition on and hold the selector button for 5 sec worked well with fuel pump relay out thanks for that

[strgas]

ok found the paper work for the 297 module the other trim pot is for fuel overlap timing .

[strgas]

the pod filter should be mounted before the maf meter just as the air box is , the engine breather hose should be mounted between the maf and gas mixer ring , spark plug choice would be NGK BP6EFS with a gap of 0.8 mm , spark plug leads any good set of low resistance spiral core top gun ,IC&E , Bosch sport , many different brands all making alot of claims . why would you want to go straight gas on this vehicle as its all already running duel fuel ?

[seanshed]

my fuel pump is playing up but I now think this sytem needs petrol under high load situations so will have to fix

[strgas]

these systems will not add petrol under high load like a injection system can , must have a secondary problem under high load , who did the install for you

[seanshed]

I brought the car a year ago with lpg already installed i think it was a ezygas instalation i dont think they still exist
would anybody recomend a good gas mechanic in the outer east suburbs of melbourne

[seanshed]

I have another breather hose coming from lpg mixer going into the airbox below filter were would i put this hose if i went to a pod filter
I have just destroyed my second airbox aaaarrrrrrrr

[strgas]

the second hose is it from the mixer or the convertor ? sounds to me its the balance line which should be fitted to the lower part of the air box for ram air so when fitting a pod filter it needs to be routed to the front of the car to pick up ram air . as for a good mechanic in the south east subs give me mate mick a ring at MECHSCAN AUTOMOTIVE SERVICES 87863989.

[seanshed]

yes its coming from the converter

I bought pod spark plugs and leads and idle is alot better and top end power

I think i will get a little extender pipe and have pod inside airbox even though air box is a bit cracked should be quieter

[seanshed]

read that if you leave pod filler screwed on loose if it does backfire it just pops off
