The liquid system has to have the flow of the gas injectors matched to the existing injectors.In your case, you have to have both ecu's tuned.

Update...Swift had a problem getting it running well on gas, so Hilbert from the Australian LPG Warehouse was coming to look at it at Pit Lane Autos today... So I will find out what is happening.It is all installed fine, just not running as well as it should... Maybe they have not wired the lume from the ICU to ECU properley? Anyway, Hilbert is the man who designed the system, so he should be able to work it out.So, in the mean time, Mick went to put the new 12psi actuator on my turbo... And when he went to put it on, found that one of the bolts was gone and one of them had fallen out onto the engine bay... So we decided to put in new turbo bolts designed by Nizpro that are not supposed to loosen as the original ones do...So we had to take the turbo off... Mick says to me... "I am going to spend some money"... LOL... I think he meant... "I am going to spend some OF YOUR money"... anyway, he said that whilst we have the turbo off, we may as well port the wastegate and fit a larger flapper valve (I am now going to call this the "whore" valve, as it has a larger flap) as I intend to move to an XFORCE 4 inch dump with with 3.5 inch exhaust in the near future... No point taking the turbo off again later, so may as well do it all at once... :-)So, I haven't heard from Mick about the gas today, except that Hilbert was coming in to look at it this arvo. We also had a problem with the VCT sensor on the right hand side of the engine, so I am not sure if this was affecting the gas system. And of course FORD being the dumbarses that they are, sent Mick the wrong part... Talk about waste people's time... Hopefully Hilbert will work out the gas this arvo and my car will be tuned on both gas and petrol tomorrow... And I will be able to join the 300+ club!!! I will let everyone know tomorrow night how it goes... My list of mods are:Nizpro Valve Springs X Force 3.5 inch cat, with twin 2.5 exhausts (Not mandrel bent upgrading soon to full XFORCE stainless with 4 inch dump and 3.5 full mandrel bent) Wastegate ported with larger flapper Rapid V3 kit (f*cking awesome piece of kit, sounds like a jet! Includes Under Battery CAI, hot and cold side piping)Walbro Fuel Pump Seimens 60lb Injectors 12PSI actuatorLiquid Gas Injection with recalibrated injectors to match flow rate of 60lbs injectorsAnd lastly a custom tune @ Pit Lane... (Tomorrow)Hope to give you some good news tomorrow night...Oh, and thanks to Mick @ Pit Lane... Working his arse off for me and other forum members!!! Thanks mate!
