gday my 94 ncII is duel fuel so im not really getting a great tune for either juices could i turn it into dedicated gas and up compression? as gas is cheaper then petrol but i dont want to lose power its a bit confusing im pretty much saying i would like to run one or the other to get an optimal tune

Hi.

My EB1 is duel fuel. I have made the best of this by using a BBM intake, and an EL Tickford Gas Duel Fual ECU which has LPG specific spark maps.

While I loose a little bit of power on Petrol due to the mixer restricting max airflow, I am more than happy with the performance on either fuel.

Re your question, yes you can run deditcated LPG, and you can then have a head shaved to up the compression.

I plan to up the compression myself, using a Tickford head, and run premium petrol to allow for the increase. I do drive 90% of the time on LPG, but like to have the petrol option there for the extra power and a bit of fun, but also for the extra range. I usually run my LPG dry and then switch to petrol. This way I get the most kms out of each tank of LPG.

Hope this helps.

Cheers

cheer's benj your setup sounds like a good option being a fairlane it will use a bit more fuel and wont be as quick as a falcon but its a cruiser i want to have some poke

Personally i think duel fuel cars are no good

I owned a duel fuel previously and the LPG doesn't last, you get a performance loss, and nor do you really save alot of money on fuel.

You're better off getting a factory fitted dedicated LPG car or a dedicated petrol one.

A duel fuel car is basically asking for a half baked meal

Just IMO
