LPG Tuning

[DF_Media]

Hi Anyone running dual fuel setups.

I am wondering if there is specific setups for LPG on the S1 VN as I have spoken to a few "LPG Specialists" and have been pretty unimpressed with the info about what they do that makes them specialist tuners for GAS.

Anyone had any experience or recommend any GAS specialists Brisbane/Gold Coast ??

my clubbie a duel fuel car, i just take it to a normal mechanic and just told them to give it a service and tune and the car runs sweet on both, i dont think gas specific places can really do much more to improve the tune of a duel fuel car.

depending on whats wrong with the lpg, running rough, backfiring? i am running lpg on my VN series I V6, manual, done all the tuning myself and runs as good as gold,

get it dyno tuned on lpg then it will be sweet as

agreed there's not much you can do with it,
a good Dyno dude could tune it or a good mechanic with ECU tuning software to tinckle with its ticker

done all the tuning myself and runs as good as gold

you got ECU tuning software / Laptop and and all that.. dang


Me: Wheels out the desktop with al the leads and goes HEY WTF!

Hi There thanks for the replies. There is nothing wrong with it actually as recently I had new Bosch lead kits and Super 4 plugs put in and had all the intakes cleaned out (alot of junk shit in there) and replaced the blown up air box with a 3A racing pod and she goes harder now.

Just interested in tuning it for GAS to run the best it can - I agree with the dyno tuning it part so will have a look at some places in Brisbane/Gold Coast who specialise in GAS.

Just been surfing the net and from the Autogas site rang Tony Motson at Coopers Plains 3277 7766 and spoke to the guy there. He said assuming leads, plugs, air filter, coils were all good (mine all replaced) then 1 hour to tune it and run it on the dyno including dyno fee $120 to $160.

Does this sound about right for you guys ?

well there not much to do with the ecu on gas, its more adjusting mixtures and idle, the best way to do this is on a dyno, normally when you get lpg put on they give you another memcal to suit gas, i have just tuned mine by trial and error, never blown up an air box or manifold, mine runs alright, got power all the way till about 4,000rpm then it leans outtoo much, so might have to take it to a dyno and change it a bit, need a gas reearch throttle body os they keep the air fuel mixture to an almost constant 14.7:1 all through the rev range, but $120 - $160 is pretty good in my opinion,

i priced a dyno tune for my vn and got told 80-100 depending on how long its on for but that sounds good

[padrickz88]

yeah i remember reading in a post that hozy got his tuned on the dyno and brought its kw's up a fair bit? so does anybody recomend a place in melbourne? with a dyno? that does tunes for gas? im running dual fuel but like 99% of the time its on gas.... so wouldnt mind getting more power from that, and if i get it tuned for gas? (howeva they do it) will it make my car run shitter on petrol? anyways i was just wondering of a place in melb and rough prices thanks heaps

[xcop5l]

it wont change the petrol side
theres a good place in geelong, where im getting mine done, ill get the name for you if you want
prices are up ^^^^

[potshots007]

yeah shouldnt make it run any shitter on petrol, depending on what gas system you got depends on what gains you will get, has anyone got on the gas research throttle bodies on this forum? i want a look at how it looks in the engine bay

[defa]

i saw a pic of someone with a gas research throttle body on a vn v8. it looked really good. didn't look out of place at all.
i reckon it was on thsi forum..

i think some of the older gas setups on efi cars were not as good as todays gas setups..
