Jasper Posted September 4, 2012 Report Share Posted September 4, 2012 Hi, I've got a miata turbo, and I am planning to get a Vialle LPI (liquid propane injection) system installed, as the fuelprices are getting unbearable (8-8.5USD/gallon vs ~3USD/gallon). I am planning to run on LPG only. The Vialle system is supposed to be top of the line, and one of the few manufacturers that offer a system that injects the LPG in it's liquid state.Â Now, I went to the Vialle distributor here in Belgium, and he's very interested in my project. He was wondering, since I have a stand alone engine management, if it would be obsolete to install a secondary ECU (piggy back system) that intercepts the signal to the fuel injectors, and converts it to LPG and drives the lpg pump etc.Â No secondary ECU would be a much cleaner/efficient/logical install, and as a plus, it would be cheaper as I won't have to pay for that ECU. Although I might lose that money on getting the car properly mapped for lpg LPG apparantly uses a variable fuel pressure, so the Link would have to be able to control that. The distributor is contacting Vialle for more specifics.Â http://www.linkecu.com/forums/G4Forum/194505001Â According to this thread, it's possible with a Link G4, but is it also possible with a Miata Link, and how would that work? Are there dealers/installers in Belgium that could do that? The whole turbo setup/link package came directly from the USA. A fuel map isn't too hard (as you get a decent base map to start with), but controlling those other factors might be quite a bit more complicated, I guess?
