I assume you're talking about a positive-pressure (multipoint) setup instead of a closed-loop (throttle-body or single-point injection), but even though the LPG would go a shorter distance across the manifold compared to a throttle-body injection, trying to get it injected in the liquid phase could still increase the risk of getting the intake manifold frozen.

I have been researching LPG and water injection lately.

LPG burns slower at slower RPMs and it burns faster at faster RMPs. Some tuning needs to be done for LPG converted vehicles. And from what I hear, it is usually a compromise (if dual fuel ability is to be maintained).

On the other hand, when water is injected the burn rate of the fuel slows down. Which could theoretically bring LPG closer to gasoline.

So after some study, if i can get LPG to behave like gasoline, my standard tune for the car would work very well in my opinion. That is what i would like my current goal to be.


I am adding some articles that i find to this thread mainly so that I can find them later on.

I'm more used to CNG than LPG, but since the LPG is vaporized prior to the injection it does sound quite odd that you would at a first stage have to add some heat to the fuel and then cool down the intake stream with a water injection.

I have the opportunity to get bigger rims and tires. But they will be wider. Will i lose or gain mileage?

Most likely lose, the more tire on the road, the more resistance.

I have hooked up torque and have been trying the pulse and glide. I am trying to keep load at %80 but the car accelerates pretty fast and i seem to prefer %70, less chance of the automatic transmission lowering gears.

Obviously it is like a brick and slows down fairly quickly. The cruise control (which is actually just a speed limiter) is fairly nice for pulse and glide.
