My setup

I will use the Yellow Keihin injectors from prins along with two vapourisors and MAP/IAT sensor.

It's vapourised injection and supports up to 47 HP per injector garanteed. I will be able to up those limits with higher pressures but there is a limit. In the future I might double the injectors up but for now I won't.

I'll use two vapourisers because I'm afraid to inject liquid LPG and try to stay as far as possible from freezing effects. The vapouriser supports till about 310 hp.

For this to work with Vems I'll have to add two parameters but as I understood this will not be a problem. According to MAP/IAT sensor in rail (Below is more info)

It will be a mono-fuel car at first and later on I'll try to develop a second base map for the petrol injectors. (discussion is below)


Further thoughs/info


The length for the injector to inject is dependant of:

What I mean is, you've got 8 injector outputs, but need 12 injectors (6 LPG and 6 petrol, assuming both are run sequentially). Possible solution is to use 6 outputs in parallel, but wire each injector set through a relay to choose between LPG and Petrol. (This should be possible.) That way you "just" change

and activate the appropriate injector relay (just make sure flyback is always connected; even during the relay switching). (MembersPage/RichardBarrington)
